File Transfer (From PC To Raspberry Pi)

Python

Hey,

I’ve two xBee Pro S2C module. I’m trying to send a image from Windows PC to Raspberry Pi with xBee modules. I configured my xBees for API mode and i can receive/send AT text messages with Python codes.

I want to send a image from my PC to Raspberry Pi Model 3 B+

I also checked this subject: http://cms.digi.com/support/forum/70518/transfer-image-between-xbee-modules-connected-raspberry-each

I made some changes and tried codes below.

PC side(sender)
###########################
ser = serial.Serial(‘COM6’, 9600,timeout=.5)
fc= ‘xbee.jpg’
File = open(fc,‘r’)
#while True:
line = ser.readline()
a= File.read()
print(str(a))
ser.write(str(a))
#############################

Raspberry Pi side (receiver)
#############################

ser = serial.Serial(‘/dev/ttyUSB0’, 9600,timeout=.5)

while True:
incoming = ser.readline().strip()

file = open (‘images.png’,‘wb’)

print (incoming)
file.write(incoming)
file.close()
content= file.read()

#################################

Then i got a error:

UnicodeDecodeError: ‘charmap’ codec can’t decode byte 0x81 in position 240: character maps to

Also an idea came to my mind. I made a script converts an image to base64 code and saves as a .txt file. I changed “images.png” as “test.txt”. There is no error occured but also there is no .txt file created on my raspberry pi.

This is not an issue for the XBee but for your Python or Arduino group.
