Description

The code:
ble2902->setNotifications(false);
in the server side BLE does not get reflected to the client even when they read the notification and indication status.

Sketch

Standard BLE_Notify.ino with added ble2902->setNotifications(false); when the client registers for notifications

Debug Message

N/A

Other Steps to Reproduce

using modified code in the server side with ble2902->setNotifications(false); after the Client has registered for Notifications and the Server has processed ble2902->setNotifications(false); when you read the BLE2902 values they are still 01 00.

I have checked existing issues, online documentation and the Troubleshooting Guide

@SuperTankMan - Could you please provide both Sketches (BLE Central and Peripheral) that demonstrate the issue and that would be used to also demonstrate a fix? Thanks!

The example you suggested has no BLE2902 object (ble2902->xxx) in the code. I want to check how exactly you have tested it and where in the code it has been used. This example is the just BLE peripheral (server).

What did you use as BLE central (client) to test it and see the issue?

See code and details in issue #6863

@SuperTankMan can we close this issue and continue only in #6863?

[SuperTankMan]

@VojtechBartoska (Sorry but No) - Frankly I think this issue although related is different the other is about default values not being set when disconnected and in this one is the new values of BLL2902 are not reflected to the client via reading BLE2902 it is possible the bug fix solution will cure both issues but I do think we should keep it until they are both resolved.

Issue confirmed.

There are actually two issues:
ESP32 BLE Server doesn't send back Descriptor when read is requested by BLE Client.
ESP32 BLE Client can't read Descriptor when it is sent from BLE Server.

These functionalities need to be implemented in BLE Library:
