Download firmware to Wio LTE CAT M1/NB-IoT?

Anybody have firmware and directions for how to update the Wio LTE CAT M1/NB-IoT board? Especially the directions for updating the SARA-R410M module itself?

I can’t seem to get any of my Seeed boards to connect to T-Mobile while my SARA-R4 EVK works fine. So, I’m suspicious of firmware versions and would like to update.



Pls have a look at the seeed wiki for the firmware and tutorial.
