How to use with ble_client?

evlo commented 1 year ago

This is not an issue, but I'm trying to figure out a way, how to use this to directly communicate between two ESP32s (toggle a light directly without wifi)

Form this https://github.com/wifwucite/esphome-ble-controller/issues/4 it seems possible

this is my server config https://pastebin.com/1RSsSULZ
this is my client config https://pastebin.com/yJgn3LU2

server exposes switch my goal is when client calls the switch service it would toggle the light, however I do get nothing in the log on server. I do NOT even get message Cannot write to BLE characteristic - not connected on client if the server is not powered on.

Hmm, I have not worked with the BLE client yet. But have you tried to connect to your server ESP32 via tablet/phone and made sure that it is working in principle? Could you also paste the logs of both ESP32s? But I agree this is a valid use case and we should get it working. And then I should describe it in the Readme.

when i tried connect from the phone i do get https://user-images.githubusercontent.com/8813196/229642024-af6989ec-225e-4e8d-b6c0-7c87ce39e671.png

and i do get message that server is connected in the log but if it try to send value as byte array 0001 or byte 01 esp does restart - that is captured in the log bellow it is weird - both are logs for the light/server, bot one on the right is over usb - i don't get at all why that is - probably esphome bug/feature

It might also by that esp32-s3 does have different Bluetooth then esp32, but i do not think I have any working plain esp32 boards

I will also try doing it in a way that switch publishes sensor that indicates click, so in that case I should be able to see change on the phone

On the client esp32 I get pretty much nothing

I just noticed this

wifi mac is F4, but bluetooth is F5

It works - even the scenario where the light is server and switch sends it notifications, also it works pretty much instantly.

wifwucite commented 1 year ago

I am glad that it is working. I feel I should really add a short tutorial about this use case to the Readme. And maybe I should think about exposing a light directly, so you do not have to use a switch. But I have to get familiar with my own code again. ;-)

evlo commented 1 year ago

I have created PR with the example configs added to the readme, at least maybe that cam help a bit
