Hey, I ran in to this issue recently, after running an apt-get update and apt-get upgrade, on a raspberry pi running MODEP, but not on official pisound hardware.
I shoddily fixed it by commenting out some offending lines in the script that enables the wifi hotspot, which caused it to just exit when it does not find a ‘pisound’ midi device. The location of the script is:
/usr/local/pisound/scripts/pisound-btn/enable_wifi_hotspot.sh
If you edit the script to comment out the common function source, and the lines for flash_leds, then you should be able to run the wifi setup script successfully:
. /usr/local/pisound/scripts/common/common.sh
flash_leds 1
# and then this at the bottom
flash_leds 20
I have not yet taken the time to fix the code properly and make a pull request for it, but it should not be too hard, and I’ll look into it shortly.
Hopefully that gets you back up and running!
