I have ported a program on an ESp32 from WIFI to Bluetooth. No other changes
I was using a looper to sample a digital in for frequency measurement

The answers I now get are some 10 times less than I got with WIFI

I ran the looper program from the tutorial along with the BT and got
345.8 loops per millisecond, well down from the ESP32: 1750 loops per millisecond
in the tutorial..

Can anyone explain this please

I also tried to run the Tutorial looper along with my looper. It would not work. I had to disable my looper to get it to work

Don't know what your are doing exactly. Note that BT is MUCH slower than Wifi. So if you transfer data in a loop and count how many data your send, you - of course - get less "loops" (loop = send data one time).

If I'm wrong: Please show us your code to understand what you mean.

Yes I realise the number is lower with other activities. what surprised me was that it is 2 times slower running BT compared with WIFI for the same program. I am using the looper to trigger analog reads for wave sampling and the lesser rate affects the sampling
