I have big problems with connecting the iTracker8211 to cellular network. Spent many days trying to send AT commands, but never get any response, quite frustrating :-/
- OS: Linux/Ubuntu
- Segger J-Link JTag Debugger
*J-Link RTT Viewer (for debugging)
- iTracker 8211 NB
- Firmware: https://github.com/RAKWireless/RUI_Platform_Firmware_GCC
I use the
RUI_Platform_Firmware_GCC firmware and flashed it to the iTracker.
When sending AT commands (like
AT+COPS=?) I do not get any response.
Only the command ATI gives me response:
Quectel BC95-G Revision:BC95GJBR01A04
I have the feeling, that the BG95-G modem is not correctly setup/initialized. the
GSM_init() looks quite different than for the
M35. Maybe here is somesing missing ?
What is the needed prozess to setup the BG95-G correctly ?
Has anyone any idea ?
thanks in advance,
