Device Synchronization Procedure

Procedure for AT Modem Demo examples (UC1 and UC3)

The AT+SCHC=SYNC command returns AT_ERROR,1,7 and the synchronization failed after several retries.

• The SCHC template that has been selected in Acklio IPCore:
  • [OPENSOURCE] ipv6-udp for UC1
  • [OPENSOURCE] ipv6-udp-dlms for UC3
• The device profile configuration

The mgt_sync_boostrap function returns MGT_SYNC_ERR and the synchronization failed after several retries.

• If the LNS connectivity is OK
• The SCHC template that has been selected in Acklio IPCore, in this case [OPENSOURCE] ipv6-udp
• The device profile configuration
