Trouble integrating a BLE esp32 sensor with custom GATT specisfications

Hi Vlad

I looked at all the instructions for custom GATT incl. the issue of RL00li and played around for a day, but am still stuck.

In bluetoothctl I have: [NEW] Device 30:AE:A4:26:3D:82 MyESP32 [NEW] Primary Service /org/bluez/hci0/dev_30_AE_A4_26_3D_82/service0028 17170000-1fb5-459e-8fcc-c5c9c331914b Vendor specific [NEW] Characteristic /org/bluez/hci0/dev_30_AE_A4_26_3D_82/service0028/char002c 17170002-1fb5-459e-8fcc-c5c9c331914b Vendor specific [NEW] Characteristic /org/bluez/hci0/dev_30_AE_A4_26_3D_82/service0028/char0029 17170001-1fb5-459e-8fcc-c5c9c331914b Vendor specific [NEW] Descriptor /org/bluez/hci0/dev_30_AE_A4_26_3D_82/service0028/char0029/desc002b 00002902-0000-1000-8000-00805f9b34fb Client Characteristic Configuration [NEW] Primary Service /org/bluez/hci0/dev_30_AE_A4_26_3D_82/service0001 00001801-0000-1000-8000-00805f9b34fb Generic Attribute Profile [NEW] Characteristic /org/bluez/hci0/dev_30_AE_A4_26_3D_82/service0001/char0002 00002a05-0000-1000-8

I configured the path in :

I have the services an characteristics files, but not sure (no log on it) if they get parsed:

But what I get in openhab is :

Any good idea, where I made a stupid misstake ? I turned on the debugging in the console for your handler, but zero feedback...so I am simply not sure if the file get found/parsed or not

Thanks - If anyone interested I can share the esp32 code.
