Laird Connectivity is now EzurioAnswer
Follow these steps:
Download Laird BL600 OTA and nRF Master Control panel from the Google Play Store.
Install Dropbox on the phone.
Compile your script with UWTerminal. Make sure the compiler version matches the one required by the development board.
Copy the uwc file to the PC Dropbox folder, and make sure you can see the same file with Dropbox on your phone.
On the BL600 board, enter the AT &F * command to erase and format the module.
On the BL600 board, connect SIO_7 to VCC with a jumper. Make sure Con12 is switched to the right for nAutorun (see Figure 3).
Press the reset button. The BL600 should be in vSP (Command mode). You can verify this by scanning with the nRF Master Control panel. You should see BL600 (Do Not Connect). At the same time, the module will respond to your AT command via its UART port. Do not close UWTerminal.
Launch BL600 OTA and select “Download File”. In the “Open From” screen, navigate to your file via Dropbox.
Scan and Connect. If BL600 does not show, press the BL600 reset button. Since TX power is reduced in vSP mode, make sure the phone is within 10 inches.
Click “Download”.
