Hi, Currently in bluez, Included Service support is under "Not Implemented" status After adding support for the same in gatt-database, i am able to verify the operation as follows. - Three primary services "1802","a00d","a00c" are created - Further, the services "a00d" and "a00c" are included in "1802". Following is the log showing Included services are added to Main service [using btgatt-client tool] I will be submitting patches for the support in subsequent patches. Please review and share your opinion. Thanks. pi@raspberrypi:~/Downloads/bluez-5.48/tools $ ./btgatt-client -d 00:1B:DC:07:33:50 Connecting to device...
