LE secure connection doesn't work

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...
