I suppose the title says it all. I am looking to use Blue Tooth. Further information is that ultimately I want to transmit MIDI data to an iPad using the screen touch sensors. But starting off with a simple demonstration Blue Tooth example will do. Thanks for reading.

Thanks, but I don’t believe that the Presto has a Pico W inside it. Correct me if I am wrong.

No, it doesn’t, but I do believe they both use the same RM2 Wifi? Either way I was thinking it may give you a hint at how to do it.

I found some Bluetooth examples but I can’t find them again. I only saved one called Simple_Bluetooth_example, and when I run that I get an error message saying:- File “”, line 7, in ImportError: no module named ‘ble_advertising’ As I said I can’t find the other examples again, the first time the…

Thanks, I down loaded all of those but I am not sure how to use them together. When I ran the BLE_advertising.py I got a load too big error. So I changed the variable controlling this #_ADV_MAX_PAYLOAD = const(31) _ADV_MAX_PAYLOAD = const(38) And it ran and gave me the output of bytearray(b'\x0…

[image] Grumpy_Mike: Any idea what to try next? Sorry, can’t help you there. :( I haven’t tried to do anything Blue Tooth related on a Pi or Pico. @Tonygo2 or @bablokb might be able to help though.

@Grumpy_Mike First question: do you understand the architecture of BLE? If not, you should search the net for a primer that gives you a basic understanding. Once you know what a central, peripheral, service and so on is, you can write code that you actually understand and can use. And I would not…

This pair worked when I wrote them. They may provide some insight. # Save as BLE_server.py # Modified to send random integers much faster # Tony Goodhew 19th June 2023 import bluetooth import random import struct import time import machine import ubinascii from ble_advertising import advertising_pa…

A very nice example. It has everything you need to understand the architecture: UUIDs, service/characteristic, central/peripheral, client/server. Added bonus is that the central is the client. All these terms sound complicated, but once you get used to them, they do make sense.

Presto Are there any Blue Tooth examples?
