Hello everyone, I’m trying to listen the UARTC_RX pin (15).
The problem is that, when I write in the terminal cat /dev/ttyS3, it immediately wraps up with the input line for the commands, without listening to the port as you can see in the screenshot.
I have all the permissions and, when I listen to the same port with Pyserial, it sniffs lots of strange data.
This is the code that I’m using:
import serial
import time
import os
btport = "/dev/ttyS3" #technically this is the port for the pins 15 (rx) and 16 (tx) - (is it right?)
btser = serial.Serial(btport, baudrate=9600)
print("ready")
while True:
newdatabt = btser.readline()
if newdatabt:
print(newdatabt)
I’m using Ubuntu 20.04 with kernel 4.9.241, Python 3.9, on a VIM3 Pro v14.
Thank you for help!
Seems like you are receiving data in raw binary format, if you are sure it’s text data maybe replace the print line to decode it to ascii, or utf-8 accordingly
Hi, thank you for your answer, unfortunately it doesn’t work and it gives me an error, both for ascii and for utf-8. By the way, I tried the same program on my Raspberry Pi (without the decode thing) and it works perfectly. I tried to change the wires, but nothing changed
Yes but, there are lots of strange data again, but this time they’re different
I hope that it is not an hardware problem…
By the way, it is reading actually some data 'cause de GPS module sends those " ` ", but the most of the input is corrupted
The GPS module is a NEO-6 but it works, because I tried to put the serial cable to a Raspberry Pi and it works perfectly. I’m using the same power port that I used for the Raspberry Pi
Hey @Electr1, I thought of something. What would happen if we created a new serial port using regular GPIOs? I Honestly have no idea of how to create a new serial port, but maybe it could work for some reason! (anyway I wanted to tell you something, I don’t want to seem rude, but can I ask you if we only write programs in Python please? I can only use Python for my project)
@SpheLC that is not necessary, it is probably due to the uart configuration itself. please try changing the configuration of the uart to read 8 bits and 1 stop bit, etc.
