Cant read characteristic value without pointer

Hello,

I am not clear about your question.

''be the same address in both functions, since the p_ble_evt write struct should just be copied byte by byte to the memory allocated for write_evt in the broken case.

Am I understanding the = operator wrong?''

Do you mean to copy large amount of data to memory?

I don't quite see how that answers my question of why the copying using the "=" operator doesn't work.

Hello,

ble_gatts_evt_write_t *write_evt = &p_ble_evt , this one is correct as the write_evt pointer will take the address of p_ble_evt (Pointer to the event received from BLE stack).

Thanks,

Best Regards,
