nrf connect SDK: Authorized BLE write (or read)

[amiramin]

Hi,

We are migrating our current nrf5 SDK application to zephyr (nrf connect sdk v2.3). And we are using authorized read/write so we can refuse the write if device is not ready. This was achieved using following code in nrf5 SDK:

attr_md.rd_auth = 1;
attr_md.wr_auth = 0;
attr_md.vlen = 1;

memset(&attr_char_value, 0, sizeof(attr_char_value));

//reply (authorize) the read or write

err_code = sd_ble_gatts_rw_authorize_reply(conn_hndl,
&auth_reply);

Is it possible to do the same in nrf connect SDK (zephyr) environment? Any code sample will be helpful as well.

Regards,

Amir

Hi Amir, 

In nRF Connect, you can in the read/write callback return with an error. It's similar to the call sd_ble_gatts_rw_authorize_reply() in nRF5 SDK. Please have a look at chapter 4 in this guide. I have just updated it with regarding read/write with authorization.
