Hi,

I see. The application need to provide the data when the rd_auth flag is set. The application will get a BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST event for the SoftDevice (BLE stack), and need to provide the reply using sd_ble_gatts_rw_authorize_reply(). It seems you do not do that. Then the SoftDevice does not know what to do, and as there is no reply, the peer disconnects after the GATT characteristic read timeout (30 s).

in HidServiceReadProblem.pcapng trace file, packet number 1179 master send a read request from Boot Mouse Input Report Characteristic and nrf did not respond to it. in my own service this problem was exist also but when i remove the read properties from that characteristic then windows did not try to read this characteristic and dc dose not happen. and also when i set the rd_auth to 0 for this characteristic with read properties is on, nrf send response to read request from this characteristic. i am new in BLE and NRF so i do not know what is exact meaning of rd_auth flag and why nrf did not respond when this flag is 1.

thanks

Hi,

I am not able to find the packet exchange from the screenshot (or anything similar) when I look at the traces on my side. Can you point at where it is (packet number) in which trace file?
