Can we use UART in a ble interrupt ?

[Thomas]

I have a ble central device. Sending commands to UART in main() works well. Sending in on_ble_evt() doesn't work (only the first char). But I see in your examples that you use UART in ble_nus_c_evt_handler()

So when can we use UART and when can we not use it ? I have problems understanding what we can do and when : I thought the BLE code is driven by interrupts and we should do only very quick things there, to be sure we finish doing them before the next BLE interrupt

Thanks

I guess first you need to make sure weather you are using a uart_fifo.c or simple_uart generally simple_uart will return this problem like just printing the first char
