FONA and Witty Pi Mini

Post by sarahdal »

I have a FONA mini GSM, a UUGear Pi Witty Mini and some I2C sensors on my Pi Zero W, so the pi can power up, send sensor data over 2G, and power down. The Witty Pi will not power up when the FONA is connected. It will power down on schedule, but the white and red LEDs stay lit and it won't power up again either through the schedule or by pressing the button.

I think this is an issue with the TX pin, is there a way to solve this?

I spoke with UUGear, who make the witty, and they suggest that if Adafruit can't suggest an answer, to try a resistor between TX and GND
