Hi,

No, there is no API for this. The application would need to keep track of this itself. From https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v7.3.0/group___b_l_e___g_a_t_t_s___f_u_n_c_t_i_o_n_s.html?cp=5_7_3_1_2_4_2_4#ga313fe43c2e93267da668572e885945db we have:

The application can keep track of the available queue element count for notifications by following the procedure below:

• Store initial queue element count in a variable.
• Decrement the variable, which stores the currently available queue element count, by one when a call to this function returns NRF_SUCCESS.
• Increment the variable, which stores the current available queue element count, by the count variable in BLE_GATTS_EVT_HVN_TX_COMPLETE event.
