Hi,

We have SIM 5320A modules. we used AT+CGMR for getting the firmware revision
we have two types of modules

1. with firmware version 1575B10SIM5320A and S2-1045M-Z0K15 on the module
2. with firmware version 1575B11SIM5320A and S2-1045M-Z0K1P on the module

The problem is module of type 2 are working good with the AT+NETOPEN command
But, the modules of type 2 are responding with ERROR.

So, we want to change the firmware of SIMCOM modules of Type 1 as Type 2 .
Please provide the information to upgrade the firmware.

Please tell us how to upgrade the firmware.

Thanks & Regards,
Saranya VDL,

They are on V14 now, to update it:
1. Download latest firmware at **broken link removed**
2. Run the QDL.exe to flash the chip
3. Confirm with AT+SIMCOMATI

Best,
Joel
