rpisigfox board does not work after

[orivaille]

Hello
on an all new Raspberry Pi 3 equiped with a rpisigfox board and the Debian cheaped with rhe Pi (Linux Raspberry 4.1.....) I ran successfully the sendsigfox.py CCDD /dev/ttySO test script.
After having done a dist updgrade , I have now Debian 8.0 , Linux raspberry 4.4.9-7+ # 884
and cannot use the rpisigfox board anymore :

pi@raspberrypi:~ $ python sendsigfox.py CCDD /dev/ttyS0
Sending SigFox Message...
Serial port : /dev/ttyS0
Receive timeout ()
SigFox Modem Error

I checked and reinstalled all .py modules : python-serial is OK
I checked the "Disable Raspberry Pi terminal on serial port " : OK

The board is OK
I set the time-out delay to x3 .. no change

I cannot get back to the previous state before upgrade.
Did you receive issues like mine ?

thanks for your help

Hello,

The following fixed the issue :

In '/boot/config.txt' disable if present 'dtoverlay=pi3-miniuart-bt' :
#dtoverlay=pi3-miniuart-bt

Add if necessary :
dtoverlay=pi3-disable-bt
enable_uart=1

Then reboot :
sudo reboot

Serial port to use is the script's default one : /dev/ttyAMA0

Hope this helps,

Maximilien.
