It all depends on the firmware in the device.

I have a cc2541 with jnhuamao firmware and get notifications and read and write to the device with the same characteristic.

The service has Uuid 0000ffe0-0000-1000-8000-00805f9b34fb called SimpleKeyService

The characteristic has Uuid 0000ffe1-0000-1000-8000-00805f9b34fb with the properties Read, WriteWithoutResponse and Notify.

Is there a source code or example - how to do that(use the same characteristic for read write and notify)? I mean a source code for cc2541 or another BLE. – GerrDott Jun 12 '17 at 18:52
