[off topic] For folks interfacing with ESP32s

I remembered a few folks here connect up to ESP32s with their PICs. There's apparently some security concerns with them to be aware of if the ESP32s are part of your system.

If you look at the update, it was originally referred to as one in the article. I'll update the topic but please try to give some leeway in the future. Not everyone is perfect. Original article title was "Undocumented backdoor found in Bluetooth chip used by a billion devices", now updated to "Undocumented commands found in Bluetooth chip used by a billion devices"

Jeremiah,
Since I use quite a few ESP32 based devices and interface them to PICs I appreciate the info. Either way it is good to know. Thank you!
