502 +
503 +
504 +User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
505 +
506 +Once DS20L Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to DS20L. If DS20L fails to get the time from the server, DS20L will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
507 +
508 +(% style="color:red" %)**Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**
