Hi all,
I have the following problem with my SIM900. I'm trying to upgrade the firmware to 1137B09SIM900M64_ST, 1137B10SIM900M64_ST and 1137B11SIM900M64_ST but problem persists.
What could be the problem?
The original firmware version is 1137B04SIM900M64_ST.
I'm using an USB-RS232 converter connected to DEBUG-PORT directly, baud rate is recognized properly.
Any idea?
I'll appreciate your help on this.
Thanks,
Cristian.
