Can't pair with Android or Raspbian

[waheedejaz]

Hi,

I am using BLE Shield 2.1 with arduino and running the simple chat example. BLE Shield appears on every other device with bluetooth (Android, Raspbian and Win10). But I can't get it to pair with any thing.

On Raspbian:
"Pairing failed - GDBus.Error.org.bluez.Error.AuthenticationFailed: Authentication Failed"

On Android:
"Pairing rejected by BLE Shield"

But when I run BLE Controller app from the RedBear on the same android, it works perfect. I can send and receive message using the BLE controller app.

I need to establish bluetooth communication with Pi3. Any ideas about what is wrong here?
