Today I asked for and retrieved firmware updates by mail from SODAQ (thanks for that). However, UEUpdater failed to update the firmware of my SARA N211 NB-IoT Shield (with crowduino).
Because the ATI9 command did not work for me, I first tried updating to version A07. But, this failed. Now my AT commands are not working anymore and if I retry to update the firmware, UEUpdater gives the following feedback for a few seconds:
“Waiting for UE to reboot to establish communication”
“Update in progress (reset UE if no response after 10 seconds)…”
Then, it fails with this message:
“Failed: Timed out trying to establish connection”
Before I tried updating the firmware, I had version V100R100C10B656 (Retrieved by executing AT+CGMR).
I already searched through the forum to see if I could fix the problem. I found these posts:
However, these solutions did not work for me. I also see posts about resetting the User Equipment, but I don’t know how I can do this.
Does someone know what I can do to fix my problem?
Thanks for the help,
