Uart communication with GPRS module when the connection has been initiated with the peripheral

[vprasath]

At first i have tried the simple uart code from nRF52 where i could send the AT commands properly and UART communication works fine between nRF52 and GPRS module.

Next i have used central project for one nRF52 kit and Experimental_app_peripheral_blinky code to another nRF52 so once the peripheral comes in the range central,It gets connected to the central device and LED starts Blinking.

I have integrated the Central project and Uart project so when the peripheral connects to the central ,i want to send AT commands to GPRS Module and also the same when it disconnects.

My issue here is,i could send half of the AT commands and LED gets ON when it is getting connected but it is getting stuck somewhere afterthen there is no GAP event is happening and also LED is not getting off when peripheral goes out of range.

Anyone Please help me get through this

Hi,

Have you tried debugging to see where the program is stuck? You should also use this debugging method to check if any error codes are returned from function calls.

Best regards,
