NMCLI should be utilized to configure network interfaces. 

You can use the USB of IG60 for a serial interface. This is particularly useful when connection to the gateway can be lost, such as configuring network settings.

The following hardware is required:

1x Serial Null Modem Cable - DB-9 (F) to DB-9 (F)

2x USB to Serial RS232 Adapter Cables

To connect:

• Connect the three cables together. 
• Insert one USB end to the IG60 and the other to your workstation.  
• On the workstation open a terminal emulator.
• Enter the COM (serial interface) port that coincides with the serial interface to the IG60.
• Configure the connection Baud Rate 115200.
• Start the connection, the root password is "summit"

AWM, if active, sets the regulatory domain and country of the 60 radio to the current location with the help of beacons it recieves from surrounding access points.

While it is mandatory to be FCC compliant, the routine to determine the location must run every 30min. This is a draw-back for softAPs created on the 60-radio as connections will be interupted every 30min. Some clients may take this less grazefully than others.

Running the AWM routine regularily is not mandatory for the other regulatory domains the 60-series is certified for, though. For those it is enough that the loaction is determined upon the first run of the routine and it as not to be repeated after that. That is what AWM-lite does.

So, for radios only deployed in regulatory domains ISED, ETSI, MIC, KC AWM-lite can be used, which also enables the seamless use of the 60-radio as softAP in conjunction with AWM(-lite).

It is also good practice to consult "app_note_60_summit_awm" which is located in the documents archive of a 60-radio software release.

The LTE modem inside an IG60-BL654-LTE can be enable with the following command:

echo 0 > /sys/devices/platform/gpio/lte_on/value

A succesfull action will be indicated by two USB interfaces appearing:

# ip addr show

1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 127.0.0.1/8 scope host lo

       valid_lft forever preferred_lft forever

    inet6 ::1/128 scope host

       valid_lft forever preferred_lft forever

2: eth0: mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000

    link/ether fa:87:d7:c4:c1:e3 brd ff:ff:ff:ff:ff:ff

    link/ether fa:96:11:12:13:14 brd ff:ff:ff:ff:ff:ff

6: usb1: mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000

    link/ether fa:96:11:12:13:16 brd ff:ff:ff:ff:ff:ff

Only usb0 is used by the LTE modem. usb1 can be ignored.

From release 10.140.0.12 there is an easy way to set the MAC addresse for the two Ethernet phys on the 60-SOM and the IG60.

The command is called "mac". Please see example below:

# mac
Eth0:
Eth1:

# mac --help
usage: write: mac [-f] [xx:xx:xx:xx:xx:xx]
       read: mac

# mac -f 11:22:33:44:55:66
Eth0: 11:22:33:44:55:67
Eth1: 11:22:33:44:55:66

# mac
Eth0: 11:22:33:44:55:67
Eth1: 11:22:33:44:55:66

To add files to a Laird Linux build, enable "BR2_ROOTFS_OVERLAY" in your config and provide it with an absolute path to the directory you would like to overlay.  Files in this directory will be inserted relative to "/".  For example, if you would like to add files to "/etc" and the path to the overlay directory is "/buildroot/overlay", create a directory "/buildroot/overlay/etc/<files>".

Adaptive World Mode should not be used when hosting an AP.  The channel hopping algorithm can cause disconnect issues in some cases.  The best option is to set the regulatory domain in firmware manually, but at the minimum the "adaptive_ww" service should be disabled.  

An HCI interface can be implemented in lieu of using smartBASIC to communicate with / program the BL654 in Laird's IG60. 

To achieve this, build the hci_uart example for BL654_DVK.

Bluetooth: HCI UART — Zephyr Project Documentation

Direct the output to a folder, for example:

west build -b bl654_dvk samples/bluetooth/hci_uart --pristine -d my_firmware

Download Ubutil—
Linux:
UBUtil Firmware Upgrade Generation Utility v1.0 – Linux / MAC | Ezurio
Windows:
UBUtil Firmware Upgrade Generation Utility v1.0 – Windows | Ezurio

Follow these instructions to create a .UBU:
Firmware Programming Guide (ezurio.com)

TLDR:

• Copy the zephyr.hex from the "my_firmware" directory in Zephyr. 

• ./UBUtil --create-key hci_uart.pem

• ./UBUtil --application-key-file hci_uart.pem --a0-version 1 --a0-compressed --a0-target 0 --a0-startaddress 0x1000 --a0-filetype 1 --a0-filename zephyr.hex --a0-keytype 1 --append-pub-key --output zephyr.hex --ubu-output hci_uart.ubu --ubu-platform 5ECB654F --ubu-flash-size 2097152 --ubu-sector-size 4096 --ubu-base-address 0 --ubu-align-length 4

• Copy the .ubu to the IG60. 

With the file on the gateway execute the following command:

• btpa_firmware_loader.py /dev/ttyS2 115200 hci_uart.ubu BL654 

Reboot the system, then check /sys/class/bluetooth for hci0.  If this sysfs node is present you've successfully created the HCI interface.  

Laird has added custom packages to Laird Linux.  These can be found in "menuconfig", under the "Ezurio" / "Packages" section.  

To enable a Wi-Fi bridge, select the package "BR2_PACKAGE_LRD_WIFI_BRIDGE" and then set the destination interface. For example, set the destination interface to "Ethernet" if you would like to bridge the Wi-Fi to a wired connection.  

The repo tool is often available to be installed using a package manager. In the case you're facing challenges with this method, or would like to directly add the repo files to your path, the following commands can be used:

sudo wget https://storage.googleapis.com/git-repo-downloads/repo -O /usr/local/bin/repo
sudo chmod a+rx /usr/local/bin/repo

When you run the repo init command for the first time you will be asked to configure your name and email. You can also set these values with the following commands:

git config --global user.email "you@example.com"
git config --global user.name "Your Name"
git config --global color.ui true

With newer builds there are no default connections for Ethernet eth0 and eth1 anymore.
That prevents the device from getting an IP address to SSH in at.

In order to be able to establish an SSH connection again, it is possible to log in to the device through the serial debug console and define an Ethernet connection with this simple command:

# nmcli con add type ethernet con-name eth-connection ifname eth1
# nmcli con show
NAME            UUID                                  TYPE      DEVICE
eth-connection  a6183425-8fd1-4e06-9ff5-7a8d0bb5b346  ethernet  eth1

Routers providing IP addresses through DHCP will now issue an IP address to the 60SOM or IG60 again. If no DHCP is available, IP addresses can be added manually:

# nmcli con mod "eth-connection" ipv4.addresses "aaa.bbb.ccc.ddd"

Use Network Manager to set an IP address as static in Laird Linux.  In the example below the IP address of ETH0 will be set to 192.168.2.150.

nmcli con add type ethernet con-name "static-ip" ifname eth0 ipv4.method manual ipv4.addresses 192.168.2.150/24
nmcli connection show
nmcli dev status

Yes, but it requires integrating Canvas Device Manager and EdgeIQ. This currently is only supported for high volume customers. Please contact your local Laird sales representative if need be.

DTM functionality is integrated into our SmartBASIC firmware preloaded on the BL654 in the IG60 Laird Linux. Activation of DTM is done by AT+DTM command as described in this application note. Instead of using our UwTerminalX program you can use e.g., microcom to connect to the BL654 and communicate (microcom -s 115200 -p /dev/sttyS2, exit microcom with ctrl-x). After that DTM commands can be exercised which in fact are binary commands sent at 19200 baud instead of 115200 used for SmartBASIC interactive mode. However, most commands are composed of non-ascii bytes and hence it is not possible to enter these into microcom or other terminal programs. The below sequence shows how to send the exit-DTM-mode command from the Linux console as an example:

Set the serial port parameters to 19200/8N1:

stty -F /dev/ttyS2 19200 cs8 -parenb -cstopb

Echo a two-byte command (0x3f, 0xfe bytes) into the serial port device:

echo -ne "\x3f\xfe" > /dev/ttyS2

The -n switch will suppress the newline at string end and -e will allow for escape’ing of hex numbers. That way it will send the required bytes 0x3f and 0xff directly and raw into the serial port device.

Other DTM commands could be sent in the same way by replacing \x3f... with different hex numbers.

You need to boot into Linux and after Login log in issue the command

fw_setenv ethaddr <desired MAC address> 

for example:

fw_setenv ethaddr AABBCCDDEEFF

and reboot

You can read out the address previously set with:

fw_printenv ethaddr

Yes, there is one pin (4) on the power supply connector that can either be configured as an input or output.

The same pin can be connected to the AD converter of the IG60s host processor by software.

Consult Lairds application note "Configuring external I/O pin of the IG60 Laird Linux variant as input or output" to configure pin4 and this tutorial to use the AD converter on the host processor:

https://lairdcp.github.io/guides/60-som-dvk-docs/1.0/ad-converter-tutor…

Please see our IG60-BL654 online guide on Working with SmartBASIC on the IG60-BL654 Laird Linux Gateway.

Once you have created the soft AP on your Linux system and have successfully connected clients to the soft AP you can issue the command:

# iw wlan0 station dump

This will get a list of connected clients. 

Note: the interface name (here: wlan0) might be different in your system.

With access to the IG60 Laird Linux console you can start the terminal program "microcom" to issue AT commands to the integrated BL654 BLE module.
The BLE modulel istens on /dev/ttyS2.

# microcom /dev/ttyS2

To exit microcom use ctrl-x.
 

You can use the Network Manager command line interface to create an open hotspot using this command:

Yes. There is a python script on the IG60-BL654 LL developer SD card image called
btpa_firmware_loader.py

This can be used to upload a new firmware to the BL654 inside IG60-BL654 LL.

There exist pre-defined GPIOs in the IG60 to control the BL654 module, which can be found under /sys/devices/platform/gpio:

• bt_nautorun: If set to 0 (low) autorun is active and and $autorun$ application will start after power up/reset and if set to 1 (high) autorun will be disabled.
• card_nreset: Setting to 0 (low) asserts BL654 reset and 1 (high) releases reset.

To exit an $autorun$ application nAUTORUN needs to be set high followed by a module reset.

echo 1 > /sys/devices/platform/gpio/bt_nautorun/value (disables autorun)
echo 0 > /sys/devices/platform/gpio/card_nreset/value (assert reset)
echo 1 > /sys/devices/platform/gpio/card_nreset/value (release reset)
echo 0 > /sys/devices/platform/gpio/bt_nautorun/value (re-enable autorun)

You should now be able to connect to the BL654 through e.g. microcom with access to the smartBASIC interactive mode:

microcom -s 115200 /dev/ttyS2

You can now use e.g. AT&F* to clear the flash file system before loading a new smartBASIC app to the module with the above Python script. (Note: CTRL-x will exit microcom).

Note: You can always check the current state of the above GPIOs with

cat /sys/devices/platform/gpio/.../value

IP stands for Ingress Protection. Its a standard we use to check the sealability of a product once it is installed.

It is composed as IP## , where first digit is for dust/solid objects and the 2nd digit, is for liquids.
Here is the meaning for each numerical code:

There exist three solutions:

Using the offline XCompiler

• Copy the relvant version of XCompiler (found in the firmware zip file for your relevant firmware version) to the folder that contains your smartBASIC application.
• Say, your XCompiler is called xcomp_bl652_1234_5678.exe and your smartBASIC app is called  jenniferRocks.sb. Then open a command prompt window in that folder and issue the command xcomp_bl652_1234_5678.exe   jenniferRocks.sb and if there are no errors you will see a file called jenniferRocks.uwc being created which is what gets downloaded to the module by UwTerminal.
• In the file name xcomp_bl652_1234_5678.exe The ?bl652? comes from the AT I 0 response and the ?1234_5678? comes from the AT I 13 response

Using the online XCompiler

• Lairds online XCompiler is available at http://uwterminalx.no-ip.org/
• You can upload a SmartBASIC source code file and when successfully compiled, the browser will automatically download the compiled .uwc file.
• Note that compiling with the online XCompiler is limted to a single source code file (#include statements are not supported)

Using the Online XCompiler Tool

• The Online XCompiler Tool is a frontend for our online XCompiler and supports multiple source code files through #include statements. You can select a source code file and the tool automatically compiles it and stores the .uwc locally.
