OOB via UART

[GabiW]

I am planning on pairing two parts of my system using OOB pairing via a UART connection. I couldn't find many examples of pairing using a physical connection as oppose to NFC and just wanted to check if there are any security issues that could arise from this approach?

Hi Gabi, 

I don't see any problem doing OOB pairing via UART as long as it's a different mean of communication other than BLE. From my point of view it's even more secure than NFC.

I guess it's just not common to use a wired connection to pair for a wireless connection. That could be the reason most of the OOB examples you find were using NFC.

Great, thank you!
