I am using an Arduino Uno with a serial connection to connect with MQTT. MQTT connects fine, but now i am trying to connect an Adafruit BME280 sensor to it. My arduino code will not upload and says:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00
I have a feeling this is a problem related to my serial connection and not my code, but I honestly have no clue because I am not familiar with arduino or cayenne. I can send my code to anyone willing to help. Any help is appreciated.
