serial debug log for a few runs with minor change if data unavailable (https://github.com/tyeth/Adafruit_Wippersnapper_Arduino/tree/uart-pm25-wip): [COM33_2024_02_08.19.40.24.715.txt](https://github.com/adafruit/Adafruit_Wippersnapper_Arduino/files/14214050/COM33_2024_02_08.19.40.24.715.txt) matching serials (use time from last one of these to jump in Com33 file): [COM45_2024_02_08.19.40.28.427.txt](https://github.com/adafruit/Adafruit_Wippersnapper_Arduino/files/14214055/COM45_2024_02_08.19.40.28.427.txt)...

Assigning to myself to retest this sensor on C6 and PicoW. There has been a commit to extend the delay in the library example before attempting to use the sensor...

Very strange, and the PING messages in theory mean it's sending and receiving a ping/pong message from the MQTT broker (i.e. wifi still active). @T-Mosher try this firmware (mostly untested...

Thanks @T-Mosher, a new build ready for you... [wippersnapper.pyportal_titano_tinyusb.1.0.0-beta.82-26-g9dda2fda.zip](https://github.com/adafruit/Adafruit_Wippersnapper_Arduino/files/15395581/wippersnapper.pyportal_titano_tinyusb.1.0.0-beta.82-26-g9dda2fda.zip) You've helped identify some shortcomings in the logging that I was previously unaware of, win win for everybody! This build is...

@T-Mosher made a minor mistake in that one, will be printing i2c failures for each success 🙃 Corrected 📈 [wippersnapper.pyportal_titano_tinyusb.1.0.0-beta.82-28-g7c55ad4d.zip](https://github.com/adafruit/Adafruit_Wippersnapper_Arduino/files/15397195/wippersnapper.pyportal_titano_tinyusb.1.0.0-beta.82-28-g7c55ad4d.zip)

Yes that's encouraging, as previously it was saying ping before it actually sent a ping, and not commenting on success or failures. Similarly the publish could fail and it would...

Very good question 😅 It's an mqtt ping, a heartbeat or keep-alive packet if you will. It sends a PINGREQ and expects a PINGRESP from the MQTT broker. The logging...

Okay @T-Mosher, third times a charm, this one should do what we've been hoping for. It announces the RSSI in the serial monitor, and successfully restarts the PyPortal Titano's onboard...

Sadly I think just lucky, which probably indicates to us a long test period. I tested a modified 82/83 and there was no reconnect when I disconnected my WiFi hotspot,...

Thanks @T-Mosher that's enough for now, really appreciate the extra feedback. Ideally it probably wouldn't reconnect serial/reboot the main device (only the esp32 co-processor). I'm going to be cleaning up...
