RG191

All Ezurio (formerly Laird Connectivity) LoRa products should be referred as LoRaWAN as they all supports its protocol. LoRaWAN protocol make use of LoRa Chirp Spectrum Modulation within a license-free sub-gigahertz frequency band that allow to transmit regularly small packets up to 15km. 

It’s important to consider that 15km can only be achieved within absolute best conditions, some of which would be an outdoor “line of sight” transmission, interference free environment, ideal humidity/temperature, highest Spreading Factor, ect… Such range magnitude cannot represent any “real world” distance transmission and shouldn’t be expected by default.

A factory reset on the RG1xx gateway can be used to reset all settings to their default values − at any time. This process restores the original "factory" condition of your RG1xx gateway. It is recommended for troubleshooting purposes or for users who no longer have access to the web UI. Please note that a factory reset is irreversible, therefore there is no way to recover your previous configuration. It is also required to reconfigure your RG1xx gateway once the factory reset has been completed. If possible, we advise developers and system integrators to back up their existing settings before continuing.

Please follow the instructions in our latest Sentrius RG1xx / RG191+LTE User Guide under section 9.8 (Factory Reset). If this approach does not work for you, try the following:

First remove the power supply from your RG1xx gateway completely for at least 10 seconds. Press and hold down the User Button. Do not release the User Button. Now restore the power supply while the User Button is still pressed. Wait until all LEDs start flashing. Release the User Button and observe the LEDs while the RG1xx gateway is performing the factory reset in the background. This usually does not take longer than 3 minutes and your RG1xx gateway might restart automatically afterwards. Do not remove the power supply while the LEDs are flashing. This means that the factory reset is still in progress.

Unfortunately, there is currently no built-in driver or software support to utilize any Bluetooth Classic / Bluetooth Low Energy (BLE) features. For this reason, the Bluetooth radio is completely disabled and cannot be used from a user perspective. Please note that from a pure hardware point of view the RG1xx gateway is leveraging our WB50NBT wireless bridge module which is featuring the CSR8811 chipset from Qualcomm (formerly Cambridge Silicon Radio or CSR), so technically proper support for Bluetooth could be implemented at a later stage in the future. However, at this time there no plans to offer a RG1xx gateway with Bluetooth support from our side.

No. Our RG1xx gateways ship with a region lock; each region is using a different power table due to different regulatory reasons and requirements which we must comply with. We do not allow nor support to modify the region settings, so you must purchase the appropriate model for the desired region of operation. If you bought the wrong model for your region, we advise you to get in touch with your seller or distributor and ask for a RMA (Return Merchandise Authorization).

Based on the part number we set the region settings during manufacturing for each RG1xx gateway individually. The only exception here is for the Australian variant where you can toggle between the AU915 and AU923 regions in the web UI. Please find a complete list of all available part numbers with the corresponding regions in our latest Sentrius RG1xx / RG191+LTE User Guide under section 2.3 (Ordering Information).

LoRaWAN version: MAC V1.0.2
Regional Parameters version: PHY V1.0.2 REV B

The access keys used in TTN v2 are not used anymore in TTN v3 the API key is used instead. Follow the below steps to create an API Key for an application from The Things Stack Console.

1. Navigate to your application.
2. Select the API Keys section on the left menu and click the + Add API Key button.
3. Fill in the Name and select the Rights of your API key.
4. Click on the Create API Key button in order to create the API key. This will open the API key information screen.

Note: Please make sure to save your API key at this point because it will no longer be retrievable after you leave the page.

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:

If your network servers is installed in Linux machine,
iptables --list shows what ports are allowed. Make sure all the intended ports are included here.

The below is an example of output on a machine that had Chirpstack installed.

If you have normal RG1xx (non LTE version) and add Ethernet to Cellular bridging capability, you can access to RG1xx UI via port forwarding but with the following requirement

• need to forward whatever external port to internal port 443 to reach the gateway on that bridging device.
• Cellular provider allows incoming connections on that port.

Yes, as long as they are operating on different networks such that AS923 sensors talk to the AS923 gateway and vice versa for AU915 devices. 

No, an RS1xx AS923 sensor will not work with an AU915 gateway because it cannot receive the downlink packets due to differing bandwidth and frequency plans used and therefore will drop off the network.

Once the RM1xx is put into deep sleep, it can wake up by detecting an external GPIO signal. GpioSetFunc can be used to configure which pin to use in order to wake up from deep sleep.

From the definition of GPIOSETFUNC (nSigNum, nFunction, nSubFunc), when the GPIO pin is configured to DIGITAL_IN (nFunction = DIGITAL_IN), nSubFunc parameter's bit 4 and 5 control when it wakes up the radio.

Bits 4, 5

0x10 When in deep sleep mode, awake when this pin is LOW
0x20 When in deep sleep mode, awake when this pin is HIGH
Else No effect in deep sleep mode

For example, the following line of code sets GPIO pin# 28 to trigger waking up RM1xx from deep sleep when it goes from HIGH to LOW. rc = GpioSetFunc(28,0x01,0x23)

Refer to GpioSetFunc defined in RM1xx BLE Central smartBASIC Extensions Guide v1.1 for more details.

End-devices do not actually make a connection with a gateway. End-devices broadcast to all gateways within range and the gateway forward packets to a network server if it can hear them. So, a gateway does not have a hard number for supporting devices and it is rather dependent on how much bandwidth a gateway can support. For example, factors such as payload size, interval of each data transmission or data rate being used can affect how much air time is consumed and therefore the gateway processes. Also environment factors should be considered.   

It's normally best to experiment with real devices in actual sites in order to figure out how many devices can transmit data without much data loss, using desired configuration/setup.

There are a number of low cost hobbiest gateways on the market based on devices such as the Raspberry Pi, paired with a Semtech SX1272/SX1276, normally used in a LoRaWAN node. These low cost gateways often are single channel devices, operating on a single spreading factor. A single channel gateway can miss many of the LoRaWAN messages broadcast. The Laird RG1xx is an 8 channel gateway based on the industry standard Semtech SX1301/SX1257 chipset providing a scaleable solution able to receive on multiple channels/spreading factors at the same time.

LoRaWAN 1.02 spec requires the end-devices to broadcast JoinReq message on Freq 923.2-923.4 Mhz.  The max output power is 14dBm. The end devices can only use SF10BW125 to join the network, which is DR2.
