Arbitrary Bluetooth read-write template application for BipOS.
This sample application prints to screen what it receives over Bluetooth (it should be ASCII-encoded data).
There is no app for sending data (yet), but you can still do so manually using an appropriate tool, such as nRF Connect. Select the bonded Amazfit Bip device, select the appropriate service (in my case, it is the service with UUID 0x3802), and write data to the characteristic with Notify, Read, Write set. Writing the byte array 41424344 should write ABCD on the Bip's display.
