Issue while creating multiple service in BLE GATT service table example
Posted: Tue Aug 16, 2022 9:03 am
Hello,
i want to add multiple service in the given BLE service table example. I tried to create another table and created attribute table manually, but before staring the 2nd service my device starts advertising and after connection I am not able to see the 2nd service that has been created.
The event after creating first attribute table
Is there any example or reference from where I can see multiple service added by using service table ?
