Error Code 0x3401

[Akbar Dhanaliwala]

Hi, I'm calling sd_ble_gatts_hvx and every once in a while I get an error code of 0x3401. I went through the SDK documentation but I could not find what that error code is. Have you seen this error code before? thank you, akbar

Hi,

I'm using softdevice 7.0.0 and last sdk,

The same error occur when i want to send notification with notifications not enables despite catching NRF_ERROR_INVALID_STATE :

err_code = sd_ble_gatts_hvx(p_bts->conn_handle, &params);  
		if (err_code != NRF_SUCCESS &&
			err_code != BLE_ERROR_INVALID_CONN_HANDLE &&
			err_code != NRF_ERROR_INVALID_STATE)
		{
			APP_ERROR_CHECK(err_code);
		}

I'm not using bond manager and CCCD attributes are initialized after BLE_GATTS_EVT_SYS_ATTR_MISSING event :

case BLE_GATTS_EVT_SYS_ATTR_MISSING:
        err_code = sd_ble_gatts_sys_attr_set(m_conn_handle, NULL, 0);
        APP_ERROR_CHECK(err_code);

How i can avoid this error ?

Regards,

Thomas
