no, in serial I only see the ttyAMA0, that is probably the UART
I get the i2c from the hat, only, ais and gps are undetected

If I cannot use the Moitessier HAT as GPS receiver with Buster and Raspi 3b or 4, What can I do ?

If it can work with usb gps receiver, what could be the recommandation ?

Then I might completely remove the Moitessier HAT since it uses power and becomes mostly useless...

Just to ensure, have you installed the following package?
https://get.rooco.tech/moitessier/buster..._armhf.deb

The error is caused if you use a wrong package.

Do the following:

wget https://get.rooco.tech/moitessier/buster..._armhf.deb
sudo dpkg -i moitessier_1.20200723-1_5.4.51_2.1.0_armhf.deb

Sorry, I'm not a technician, just copy / paste. Where am I wrong?

Unfortunately the forum software obviously shortens the link, so it is invalidated.

Click on the link and save the file on your Pi. Then you can skip the wget command.

Thanks @nebosa e @Rooco meanwhile I have another sd with 4.19.97 kernel fully functional ... the latter makes me crazy.
