Unable to upload sketch for ESP8266 due to some elf2bin.py error #7253
Description
Hello,
i am trying for hours to get a sensor sending data over wifi to my flask server.
however due to some reason of esp82 error link below i cannot upload the sketch.
it worked 2 times in 4 hours for me seemingly random.
if anyone could help me i d be very thankful
