You are right, the long range capabilities are supported from nrf52833 on. Anyways, looking forward to this update for the Bangle.js v2.0 software. Are there any plans to have a new version of Puck.js with the latest Nordic SoC?

Regarding BLE 5 features, I am looking forward to support for extended advertising and scanning. (ex: LE PHY Coded for long range). I was pretty excited to see in the KickStarter - Bangle.JS2 software specs that "BLE 5 Central/Peripheral" features will be supported. Any updates on the timelines? Thanks for the support...

Hi Gordon,

Thanks for the response. I tried the same with a different setup: Bangle.js being central (scanning advertisements) and a peripheral running on an external nRF board.

• In NRF documentation, I saw that for Level-4 LESC, authentication is also mandatory so eventually it has to be lesc:1, mitm:1.
  
• The peripheral starts the bonding process by generating a pass key and I developed a keyboard app on Bangle.js to enter this key; nevertheless received the attached error on the peripheral. (public key is not valid)
  
• When I use nRF connect app on my phone to pair with the peripheral, the bonding works properly but not from my Bangle.js with the setting {lesc:1, mitm:1, keyboard:1}.
  
  

Any clue why I get this "public key is not valid" error?

Thanks again for the support...

Hi all,

I have Bangle.js and Puck.js devices but couldn't establish LE secure connections between them.

Puck.js has the following service configuration:

NRF.setSecurity({lesc:1});
NRF.setServices({
  0xBCDE : {
    0xABCD : {
      value : "Hello",
      readable : true,
        security: {
          read: { // optional
            lesc: true
          }
        }
      }
    }
});

Bangle.js also has the LE secure connections enabled with the following configuration:

NRF.setSecurity({lesc:1});

Nevertheless, when Bangle.js connects to Puck.js and accesses to the read characteristic, it fails to read.

I also tried to connect to the read characteristic using the NRF connect application. After I connect to Puck.js and try to read the value of characteristic, it triggers bonding and stuck at that stage with no success.

Is there a known issue with the lesc or am I missing something?

Thanks for the support in advance...
