I have a custom circuit board which is using a Bluetooth LE chip from Nordic Semiconductor. I'll be talking to this device with an iOS app and am new to BTLE and somewhat confused by the whole discovery/pairing flow. Our device simply sends out ASCII text which is a custom data format.
The EE who developed this board hasn't given me a lot of guidance on how to connect to it. When I use the LightBlue iOS app I can see the device and it's UUIDs. The UUIDs I see are exactly the same as the UUIDs in the Nordic nRF UART App.
My main questions are:
- What UUIDs will my boards need to use? There will be more than just one board, so it seems like each one will have it's own UUID?
- Does my device need to get some "special" UUID from bluetooth.org?
I know there are different UUIDs for both the service and the characteristics...my questions apply to all of these.
