RE: GSMA 7.245 to 8.017 - slychiu - 12-27-2024
UCM/4G A7608 ARM Firmware GSMA 7.245 for A7608 4G module with VoLTE
New UCMA/GSM 7608 4G/LTE GSM Module supports VoLTE for Voice dialing.
With the end of 3G GSM Networks in several countries, the UCM/4G GSM Module (SIM7600) is not able to dialout as the old module does not support VoLTE. It can still send and receive SMS.The new UCMA/GSM7608 with Arm Processor is the replacement which can dial by Voice (using VoLTE) and and/receive SMS
The UCM/4G cannot be upgraded to the new GSM A7608 submodule as the base module is not compatible.

GSMA 8.004
This firmware allows SIM7600 (used in the UCM/4G) to be plugged in to the GSMA Arm baseboard.
However A7608 GSM submodule CANNOT be plugged into UCM/4G (non-ARM) PCB

GSMA8.004 has been suspended for the time being, We are investigating a problem of wrong time updates

GSMA8.005
This fixes the bug where the SNTP automatic time update gives the wrong time perhaps several times a day. Please upgrade

GSM4A 8.017
. GSM5 supports a new GSM Module Quectel EC21 as well as A7608. Otherwise the functions are the same as GSM4A 8.005
This version allows upgrade to GSM5
