[TriEmbed] ESP32 ESP-IDF BLE client multiple services per device

[Michael Fulbright]

I've been working on a personal project using an ESP32 combining info 
from an exercise bike and heart monitor band and displaying it on a TFT 
LCD.  The TFT/touchscreen is working and I can connect to individual BLE 
advertising services just fine.  I'm not trying to integrate all the BLE 
services at once.

I've gone through the ESP-IDF BLE examples related to clients.  They 
seem to cover connecting to a single service on a device or multiple 
devices but not handling multiple services per a single device.

I'm having trouble understanding how to leverage the callbacks you get 
in this use case.  I understand the single service per device well 
enough but adding the wrinkle of multiple services per device seems to 
complicate matters.

I'd like to use ESP-IDF for this project so I can learn more about it.

I just wanted to see if anyone here is familiar with this use case and 
might be able to give me some assistance.

Thanks,
Michael Fulbright
