EC25AUFAR06A09M4G - AT+IPR command not saving baudrate, new firmware

Technical Subjects
1

Hello,

I’m trying to change the baudrate on the EC25AUFAR06A09M4G via AT+IPR from 115200 to some other arbirary baudrate from the list of supported baudrates, afterwards AT&W command is sent to write and save the new configuration but to no avail. The modem responds always with OK and when querying the baudrate with AT+IPR? it always returns 115200. What could be the cause that the modem does not accept the new fixed baudrate?

Also, is there a new version of firmware available for this part, currently my version is (AT+QGMR?) EC25AUFAR06A09M4G_01.001.01.001?

I have sent the latest firmware to your email, pls try again

Sent an email to your support, awaiting the approval to use your Customer FW Download Tool to install the firmware. That is all I need to install the attached firmware, correct?

Also, why wouldn’t the AT+IPR command work on previous version of firmware?

I have sent you the Qflash. You can use it to upgrade. There might be some bugs in the old version.
