BLE runs only while debugging off

[achraf]

I have problems with my custom board.

I developed the firmware with the nrf52832-dk custom and there the firmware runs standalone (with RTT logs on and without) .

but now the firmware work well but when I want to see debug terminal the ble is off, and when I stop debuging the ble become ON and it apears ,
I see that what cause this probleme is: NRF_LOG_BACKEND_RTT_ENABLED.
now when I m disbabling it the ble work fine and apear on my phone but, when I want to active that, I can see my debug but the ble become OFF 
any ideas ?
btw even if with release mode or debug mode its the same the problem, I'm with working with SES

Hello,

Please make sure the SEGGER_RTT_CONFIG_DEFAULT_MODE config option is set to either 0 or 1 in your sdk_config header. Otherwise, the RTT backend will become blocking when you don't have a debugger reading the RTT messages connected.

Best regards,

hello,
thank you for the answer :I did SEGGER_RTT_CONFIG_DEFAULT_MODE to 0 or 1 :-(, it seems still the probleme ,the BLE is OFF when I debug, unless the NRF_LOG_BACKEND_RTT_ENABLED is 0 and no printf in my code. otherwise the ble doesnt work if I debug

Can you check if the program enters the app error fault handler (Error module) when you debug with NRF_LOG_BACKEND_RTT_ENABLED=1? Also, is printf used with RTT in your app?
