How to identify HSPI as default SPI?

I have an ESP32-WROOM trying to use the XPT2046_TOUCHSCREEN library by Paul S. His library uses the default SPI pinout which I believe is automatically set to VSPI. I have a setup where the XPT2046 is wired to the HSPI pins on the ESP32. How can I select HSPI to be the default SPI seen by Paul's Lib...

BLE Client & BluetoothSerial (Classic) same time?

I'd like to use both BLE Client to receive data from BLE sensors AND bluetoothserial.h to allow BT Terminal connections. Is there and Arduino IDE code example or library to configure this? I understand it is possible with the ESP32, but am unable to find a clear working example.

Thanks!

Re: ESP32 ADC Non-linear Issues - How do I fix / change Attenuation or width?

Yes, I have working sketches for using temp sensors.... the issue is fixing the ESP32 ADC internal problems. While the correction of the non-linearity is one thing, I am disappointed that the ADC lacks consistency even with the corrections applied. Have decided to use an external ADC instead.

Help with OTA via Bluetooth Classic

Working with ESP32 (ESP32-WROOM-32D). Would like to have OTA via direct Bluetooth classic, but I don't have the skill/knowledge to create the proper sketch. I've read that it can be done using the current OTA as a template and just changing the WIFI access to BT access... which I don't know how to d...

Re: ESP32 ADC Non-linear Issues - How do I fix / change Attenuation or width?

I could use help in the specific sketch to measure the VRef on my ESP32. I've seen where it says to use this or that command, but when I paste them into my Arduino sketch, they all fail.

Sorry for being inexperienced, but could really use the help.
Thanks,!!!
