There's multiple ways to add security.

  1. Secure the pairing with the SecurityManager. An example app is here (it's mbed 2, but I think the API is still the same).
  2. Secure characteristics by calling requireSecurity (see here).

Accepted Answer

Hi,

Thank's for your answer, when i added SecurityManager and initializeSecurity for a passkey. this is what i get : _ i can connect with the target. _ when i wan't to read or write data from the the secure service the ask me to associate with the Bleutooth. _ When I want to associate with it, first i can't find the Passkey and it's mentioned either 0000 or 1234. But the len of passkey is 6 and all passkey don't work. It's normal. Thank's again.

You can set the passcode on device through init method of SecurityManager (fourth argument). By default it generates random passcode which you can see on device by attaching on the onPasskeyDisplay function.

Maybe you can remove requireSecurity when the right valid is written to the characteristic, but I'm not sure.
