Thank you.I find the way.

Finally reading the comment at the signature of this SVCALL you get / * @retval ::NRF_ERROR_FORBIDDEN The connection's current security level is lower than the one required by the write permissions of the CCCD associated with this characteristic.*/.

Voilà, it took us 2 minutes. Good luck with your urgent project;)

Come on, that's trivial:

You will look where function ble_hids_inp_rep_send is implemented in SDK. It either is implemented in source code (and then you simply read it or even put some debug into it if not present) or just in header files as SVALL directly to SD (in that case you should get explanation of all possible error codes. This is the first case so we jump to file components\ble\ble_services\ble_hids\ble_hids.c.
Now you see that the only way how this error status could be returned is by call of SD API function sd_ble_gatts_hvx. So you will find its signature in header file components\softdevice\s132\headers\ble_gatts.h.

Hi,I'm sorry about that. The reset is caused by calling ble_hids_inp_rep_send, and the err_code is NRF_ERROR_FORBIDDEN. Could you please tell me how is that ocurred?

(Why? How should we know with such poor info supplied?! It's great to know that it's urgent and the whole universe should help you ASAP - for free - but you don't bother to supply any debug information:)

Debug, debug, debug, debug. What UART or RTT logging says when enabled? On which line in your source code hard fault or asserted error code from some SD or SDK function return occurs?
