NRF_ERROR_BUSY from sd_ble_gattc_primary_services_discover after iPhone restart

[Cyrus Cheung]

We are using nRF52832 to develop our product with the ANCS function.

But after bonding with the iPhone and then restart the iPhone, an error message "NRF_ERROR_BUSY" will receive.

The cause seems come from "sd_ble_gattc_primary_services_discover" in the function "discovery_start" in ble_db_discovery.c and it causes "p_db_discovery->discovery_in_progress = true".

Could anyone give me some advice on how to solve it?

First, create a app_timer(APP_TIMER_MODE_SINGLE_SHOT about 2-3s timeout)

then when check the  NRF_ERROR_BUSY  , start-up the app_timer created, call sd_ble_gattc_primary_services_discover again in the callback function of ther app-timer
