i am working on controlling rgb led with nrf52832 using ble which is based on ble_app_uart example script so my script is working properly on your development board everthing is fine but as i upload this script to a normal nrf52832 module which is like a custom nrf board in which having only one external crytal oscillator my script was not working on nrf module board but i have seen "">devzone.nordicsemi.com/.../code-flashing-successful-but-not-working" this link and recorrect something then my ble initail to discover but as i connect it with my nrf connect application then once is connect propery but as i send any as a payload then noting goes there and in second time program get crashed and nothin responce
after debugging i get my script everytime get stucked at
debug data
<info> app_timer: RTC: initialized.
<info> app: Debug logging for UART over RTT started.
<info> app: Connected <info> app: Data len is set to 0xF4(244)
<info> app: p_evt->type: 2
<info> app: BLE_NUS_EVT_RX_DATA: 0
getting stucked after this and
