Disconection occured in a random way[Reason : BLE_HCI_CONNECTION_TIMEOUT]

[Mehdi]

Hi,

I'm interfacing acceleration via BLE using NRF52.

I'm using timer to get the sensor value and update the characteristic value related to this sensor using sd_ble_gatts_hvx every timeout_ticks value configured in app_timer_start API.

When i set timeout_ticks above 500 ms, the BLE works corrcetly, in the opposite case, a disconnection event occured in a random way with the following reason : BLE_HCI_CONNECTION_TIMEOUT.

Thank you in advance.

Hi Peter, The interrupt priority i'm running at RTC1 is 7.

below, the treatment performed in acceleration_sample_handler() :

	Acc_Value AccData;
	static uint32_t err_code = NRF_SUCCESS;

  memset(&AccData, 0, sizeof(Acc_Value));
  readAcc(&AccData);
	
	err_code = ble_accs_acceleration_update(&m_accs, (uint8_t*)(&AccData));	
	   
	APP_ERROR_CHECK(err_code);

I can't share the complete project but i can send you the main.c and board_definition.c if you want.

Thank you
