ESP-IDF Issue - Max Notification Reached, registration failed

[benedikt-bartscher]

First of all, thank you for this awesome esphome component.
I tried to pair with "Alexa Remote Pro" but while reading the characteristics it fails with this error:

E (18960) BT_APPL: Max Notification Reached, registration failed.

which is caused by espressif/esp-idf#6376.
I think there is not much we can do in this repo, i just wanted to keep track of the issue.

What esp are you using? I've been using a fire remote pro with this since it released. Although I stayed with a previous revision because the new version didn't recognize the difference between the newest buttons and 4 on the bottom.

[benedikt-bartscher]

I am using a LILYGO TTGO T-Internet-POE ESP32-WROOM. I will try some other remotes later.
This is the remote i ordered: https://www.amazon.de/dp/B09SVVVG16?psc=1

[Bretthansenpc]

How much PSRAM is on that? That's the same remote I have and mine works great I only have 1.3 megabytes of psram on mine

[Bretthansenpc]

If I remember correctly the wrooms don't have internal psram. And I just checked that version it has no psram at all so that is why it runs out and panics

[benedikt-bartscher]

Thank you for pointing me to psram. I just ordered some esp32-wrover modules which seem to have internal psram. I will report my results if they arrive

[benedikt-bartscher]

I just flashed my new board with internal psram. I still get the error msg: E (18960) BT_APPL: Max Notification Reached, registration failed.
However pairing works fine and all keycodes get logged if i press buttons.

Another thing i noticed: The "Last event value" entity only changes from 0 (idle) to 1 (any btn pressed). Shouldn't it show the last pressed key?

For reference, here is my full log:

[fsievers22]

Thanks for your feedback. The last pressed key should be shown in a text_sensor but apparently it does not work currently.
I will try to fix it as soon as possible.

The error about max notifications reached seems to be from the underlying software stack and probably the remote would like to register more characteristics for notification than the esp32 can handle. I don't think I can do anything about that.

[benedikt-bartscher]

You are welcome. I will open a seperate issue for text_sensor not working with the latest esphome.

About the error with the max notifications: I know this is not an issue with this repo/code, thats what i mentioned in the first comment of this issue: "I think there is not much we can do in this repo, i just wanted to keep track of the issue.". You can leave it open to keep track of it or just close it if you want.
