NR7101 Module Firmware Upgrade Fail

Thanks very much @Mayone78 for the screenshot.

This shows that your NR7101 is running 13A02 module firmware.

This means that the DFOTA upgrade file that you need is the one that is 13A02 to 13A04

Kind regards Tony

Does the online module upgrade check work at all for you @Mayone78

If not then I am stuck.

Kind regards Tony

that doesn't work either.

Any news from Zyxel about R13A04 not working?

Same here. There is a version mismatch in respect of:

RG502QEAAAR11R13A02-R13A04

as listed here:

Look inside the zip file and the file "quectel-project-version":

Project Name: RG502QEA_ZYXEL_VA
Project Rev : RG502QEAACR13A02M4G_ZYXEL_01.001
Branch Name: SDX55
Custom Name: STD
Package Time: 2022-10-08,15:26

Notice the AACR, but the modem reports:

ati

Quectel
RG502Q-EA
Revision: RG502QEAAAR13A02M4G

That is AAAR.

This gives an error 505 on upgrade (here attempted manually):

OK

+QIND: "FOTA","HTTPSTART"

+QIND: "FOTA","HTTPEND",0

+QIND: "FOTA","END",505

which relates to a version mismatch.
