LEGO HUB Technical Twin: Adjusting missing parameters

[ruppie]

Hello,
please have a look on the picture attached.
Left hand side shows my ESP32 device
Right hand side is LEGO original.

I got a litle bit lost which parameters have to be added and where to find in Lib / structures, to make my Device looks like the original.
Thanks in advance for your helpfull advises and hints

Marc

For sure you are missing CCC descriptor (BLE2902) on that characteristic.

I think you can ignore differences in other parts.
For sure you cant change the fact that Generic Access characteristics are read only. I doubt IDF bluedroid have such option.
