I'm using the Rpi 3B+ and understand the hardware uart is used by the bluetooth. I'm OK to use the other uart
I've followed several threads and believed I've done all I can.
- Enabled the Uart in config.ini
- Set the 'core_freq=250'
Disabled the Console in cmdline.txt
(I've double checked using the config tool)
This command shows the serial ports
ls -l /dev/ttyS0 /dev/ttyAMA0
.. and shows
crw-rw---- 1 root dialout 204, 64 Feb 28 14:17 /dev/ttyAMA0 crw--w---- 1 root tty 4, 64 Feb 28 14:17 /dev/ttyS0
But this python command only shows one port.
python -m serial.tools.list_ports -v /dev/ttyAMA0 desc: ttyAMA0 hwid: 3f201000.serial 1 ports found
What am I missing here.. ( inexperienced user )
