D Declan Well-Known Member Licensed User Longtime User Jun 30, 2020 #1 I am going through the BLE 2 example. In order to send data to the remote BLE device (uBlox NINA), I must send: B4X: WriteData(Service As String, Characteristic As String, Data As Byte()) What exactly is: Service As String and Characteristic As String Where do I obtain these?

E emexes Expert Licensed User Longtime User Jun 30, 2020 #2 You can get Service and Characteristic IDs when you connect to the device and do a ReadData, but I think these are usually of readable characteristics rather than the writeable ones. User nRF Connect app (free ✌) to manually connect up to the device and explore what it offers. Pretty sure it will show both readable and writeable characteristics. Also lets you manually read and write data from/to the device. Upvote 0
