Not issue - but this might be helpful for Spark traffic sniffing

[paulhamsh]

Hi Justin
Very impressed with what you and team have done here!!

I haven't tried Wireshark, but wrote this for an ESP32 board (M5Stack Core2) to appear to the Spark app as the amp and record the traffic sent to the amp and show it on the Serial Monitor (in the Arduino program).

Next step is to send this over wifi to something connected to the actual amp (via bluetooth) and capture the return traffic - I've started on that using a Pi 400.

Only works with Android - I think iPhone must use BLE not bluetooth serial?
