Ok we saw the error, we don’t have the right fraquency band, the function getfrequencyBand return now 1 and no 0, I tried to change it but it didn’t work ( I did dot->setFrequencyBand(0); ) Somoene had the same problem?

Hello! I’m not sure about how I see the exact revision number, but I was working with the mbed-os in the exemples, and the libmdot-mbed5 https://developer.mbed.org/teams/MultiTech/code/libmDot-mbed5/ the stable (2.0.15 I think ) version.

Then I Update the version of mbed-os so I suppose my mbed-os is the last version stable. And the version of libmdot is the dev version https://developer.mbed.org/teams/MultiTech/code/libmDot-dev-mbed5/ (2.0.16 I think ).

It’s the same mDot, and it’s exactly the same program. When I launch it, it remove my config, set the password and name, also the class and then Save the config and joinnetwork. With the older version the mDot join the network but not with the new library. So I search Why, and I saw that when I use getFrequencyBand it return 0 with the old library (it’s normal i’m european) and it return 1 with the new library, and so it’s normal that I can’t join the network..
And I can’t change the band with setFrequencyBand, is that normal?

I don’t have the mDot right now so I can’t exactly the error message but it’s the usual message, the same that when I make a mistake in the password of network for example.

Ok so I have the libmdot version 2.0.16-7-ga61aab1 and mbed-os revision 5.4.3 and it’s not working.

It was working when I had libmdot to 2.0.15 and mbed-os to 5.1.5 but sensors were not working.

I have this debug logs :
failed to join network – -4:Join Error, Failed to join network

Sometimes after several debug logs I also have this log :
failed to join network – -4:Join Error, Join backoff

And I also printf my frequencyBand : 1 so it’s the american,
and Tx = 0 Rx = 923300000
