I am programming with nrf52833,ncs v2.9.0.Based on peripheral_hid_keyboard and cetral hid.
I send about 6k hid keys to central via ,while sending,peripheral side
err = bt_hids_inp_rep_send(&hids_obj, conn_mode[i].conn, report_type, buf, len, NULL);
But ERR report that
E: Failed to allocate new MPU region 73
How this happend?Do there any ideas to solve this?
