It seems like the notecard sometimes get stuck in a state where it does not respond meaningful over I2C. It does respond over I2C, but does not send a response (I set a timeout for 2 seconds). Eventually I had to do a hard reset to get it working again. Any idea what might be going on?
I could not figure out what the LED pattern was related to this: What do the Notecard LED blink patterns mean?. But both were one, maybe one green/yellow + red with some intermittent blinking going on.
Maybe I need to hook up the reset pin to be able to do a reboot from the host MCU?
