Read characteristic from server side

• Development Kit: [ESP32-DevKitC]
• Kit version (for WroverKit/PicoKit/DevKitC): [v4]
• Module or chip used: [ESP32-WROOM-32D]
• IDF version (run git describe --tags to find it): v4.0.1-193-ge7ac221b4
• Build System: [Make]

Problem Description

Is there any AT Command which lets the server read the value of a certain characteristic?

It's needed for our project to be able to read a characteristic value from server side. We need to know from server side the value of a characteristic which is defined in build time and it's not gonna be changed until ESP32 module FW is updated.

Expected Behavior

AT command for reading characteristic value from server side

Actual Behavior

No AT command for this purpose

This feature is not supported at the moment.

Thank you, @xiewenxiang .

Is there any plan of including this feature in future versions of esp-at?

Kind regards!

If everything goes well, it is planned to be completed by the end of next month.

Thank you, @xcguang .

We will consider whether waiting for that version or trying another method to read that value instead.

Kind regards.

Hi, @xcguang.

When is it planned next esp-at version to be released? Is it going to include any AT command to read a characteristic value from server side?

Thank you!

@HectorJimenezMendez At present, ESP-AT master has implemented AT+BLEGATTCRD command on the server side. If you still need these functions, please test and develop based on ESP-AT master
