Hello,

Please make sure to have DEBUG defined in your preprocessor defines, like shown in the included image:

This will make your logger output a detailed error message whenever a non-NRF_SUCCESS error code is passed to an APP_ERROR_CHECK.
Please do this, and let me know what the error message reads, along with which function that returned the error code pointed to in the error message.

Best regards,
Karl

Which function returns this error code? Please check the end of the error message to see where the APP_ERROR_CHECK was triggered.

Hello,

yes, i got where exactly its the function service_init()  in that ble_cus_init() it returns err_code 7 please

have a look at this ,

thank you,

So it seems your ble_cus_init function is returning the NRF_ERROR_INVALID_PARAM error.
How does this function look? Under what conditions will it return this error code?
Likely it is just forwarding the error code generated by a SDK function it itself is calling.
