Raspberry3b, Python3, Combine 2 codes which work by themself (Thonny, Geany) but not together in the same IDLE

Question

I have to combine two codes and run them one after the other. Unfortunately, I can't start the gps_receiver on Thonny_ide and neighter the other code on the default Geany_ide.

Can somebody help me to solve the problem? Here's my code:

GPS_Receiver (uses the waveshare gps head)

import serial
import time

# Enable Serial Communication
port = serial.Serial("../../dev/ttyS0", baudrate=115200, timeout=1)
# Transmitting AT Commands to the Modem
# '\r\n' indicates the Enter key

time.sleep(.01)

# Activate Command line
port.write("AT \r\n" .encode('utf-8'))
rcv = port.read(100)
print(rcv)
time.sleep(.01)

# Power On the gps module
port.write("AT+CGNSPWR=1 \r\n" .encode('utf-8'))
rcv = port.read(100)
print(rcv)
time.sleep(.01)

#Set the baud rate of GPS
port.write("AT+CGNSIPR=115200 \r\n" .encode('utf-8'))
rcv = port.read(100)
print(rcv)
time.sleep(.10)

chk = False
search_for = '3D'
while chk == False:

    port.write("AT+CGPSSTATUS? \r\n" .encode('utf-8'))
    rcv = port.read(100)
    print(rcv)

    is_in = search_for in rcv
    if is_in == True:
        chk = True
        break

print(chk)    
print(rcv)


#Send Data received to UART
port.write("AT+CGNSTST=1 \r\n" .encode('utf-8'))
#rcv = port.read(100)
print(rcv)
time.sleep(2.5)

port.write("AT+CGNSTST=0 \r\n" .encode('utf-8'))


#Print the GPS information
port.write("AT+CGNSINF \r\n" .encode('utf-8'))
rcv += port.read(200)
print(rcv)
time.sleep(.1)

data_raw = rcv.split(',')
print(data_raw)

index_N = data_raw.index('N')
north_str = data_raw[index_N - 1]
north_float = float(north_str)/100

index_E = data_raw.index('E')
east_str = data_raw[index_E - 1]
east_float = float(east_str)/100


location_N = str(north_float)
location_E = str(east_float)
altitude = str(data_raw[9])
satelites = str(data_raw[7])
print('location: ' + location_N + ', ' + location_E +', altitude: ' +altitude+ ', satelites: ' + satelites)
data_list = [location_N, location_E, altitude, satelites]
print(data_list)



#Stopp sending Data received to UART
port.write("AT+CGNSTST=0 \r\n" .encode('utf-8'))
#rcv = port.read(100)
#print(rcv)
#time.sleep(.5)

Error, when run in Geany's Programing Editor:

The Kamera doesn't detect the qr codes or doesn't write it in the terminal. And when pressed 'Ctrl+C' on keyboard the whole program shuts down.

In the best case I would like to run the whole prgramm in Thonny. So basicly just insert and activate the gps funktion in it.

Thanks!!

Answer 1

By default Geany runs Python code using Python2. This can be changed under 'Build','Set Build Commands'. Then change Compile from python to python3 and Execute from python to python3.

The serial read commands changed between Python2 (returns string) and Python3 (returns bytes), adding a .decode() converts bytes to string.

If not sure which version of Python is being used add:

import sys
print(sys.version)
