DA14583 IoT sensor dongle connecting to external BLE client

Hello Dialog,
We are having an external Gateway which is BLE 4.0 supported. I have configured the external gateway as a BLE GATT Client for reading the sensor data of DA14583 IoT sensor dongle. I have able to read the data once it connected to DA14583 Dongle, but the problem is connecting to DA14583 Dongle based on BD address it is connecting and disconnecting at the same instant please find the attached log of AT commands by BLE Client.

AT+QBTGATCCON=1,"B001",D9D400CAEA80,1 //B001 is client Id, D9D400CAEA80 is BD address of DA14583 Sensor Dongle
OK

+QBTGATCCON: 1,0,"B001",D9D400CAEA80,1 //Connected

+QBTGATCCON: 0,0,"B001",D9D400CAEA80,1 // Disconnected

To reconnect the dongle I have to restart(power on-off) both the client and server and run the complete AT stack of code in the client for reconnection still it won't connect, but if I am lucky it will connect successfully. Once connected I can read sensor data without any issue.

What may be the problem Is there any limit in DA14585 connection interval time or restricted access for external BLE modules?

Please clarify.

Thank you.

Regards,
D.Vishnu

Hi vishnuatdialog,

Hi vishnuatdialog,

Be aware that there isn’t any limitation in DA14585 connection interval time or restricted access for external BLE modules. I suppose that these AT commands are from the side of the external gateway, because we don’t have any kind of these commands, so I am not able to know their functionality. Could you please let me know if you have any other issues from the side of the DA14585?

Thanks, PM_Dialog
