Need help please pi 3 i need this /dev/serial0 -> ttyS0 change to /dev/serial0 -> ttyAMA0 for my hotspot think this need to edit to make it change /dev/serial0 -> ttyAMA0 thanks for the help.

Are you saying /dev/ttyAMA0 doesn't exist or are you asking why /dev/serial0 points to /dev/ttyS0?

/dev/ttyAMA0 missing in my pi os need it for my sas818 hat. ▶ ···

That's odd. Try running raspi-config and look at Interface Options -> Serial Port. Make sure login on serial is disabled and hardware is enabled. You'll have to reboot after changes.

Have done this but nothing change.

I was reading about config.txt think this is the issue can somebody send me copy of the file and I can compare mine to it thank you. Regards VA6RBC. ▶ ···

The manual has what you should need. sa818 - SA818 RF Modules - AllStarLink Manual SA818 RF modules are inexpensive RF transceiver modules, often used to build a personal RF "hot spot" AllStarLink node. | AllStarLink Manual
