BC127 Melody 7.1 BLE bonding - BLE_SECURITY


#1

Hi,

I’m testing the new Melody Firmware V7.1, Bluetooth pairing/bonding. I received the following message on a bonding attempt:
BLE_SECURITY 14 3
The user guide (Melody Audio 7.x, Rev 3 Aug.18) is not mentioning other states than ‘0’ (success) and ‘1’ (fail).
What about the ‘3’ in my received message? And maybe other states?

A proposal for the user guide: BLE_SECURITY is listed only in commands and is missing in notifications.

Regards,
Alex

No information available?

Alex,

We are adding more detail in the next release of the manual but this is what it means.

  • 0: Success
  • 1: Pairing in progress
  • 2: Link key missing
  • 3: Fail

Essentially you need to make sure that the other device is bondable and retry.

Regards

Matt
