Hi Folks,
I am just asking general information (explanation and/or code samples examples) to set up a secured BLE connection between multiple centrals towards one peripheral working as BLE uart.
Her are my concerns for the moment:
I plan to use preconfigured random static adresses for each central stored in flash memory but also for the peripheral one.
-At this stage, I am asking to myself if I can launch a pairing on demand I mean on a specific hardware action I want to launch the pairing process which store the bond info in peripheral whitelist. I only see pairing at BLE initialisation. Could we launch a pairing on demand when BLE is already active?
-I also want to secure the bond creation during the first pairing phase to avoid an unknow device to bond on a sapre whitelist element so I understand there are many ways like presharing keys , LESC with passkey so that the ones which have the pass can proceed the pairing. Could you please me orientate toward sample code within SdK who do the job?
-Once pairing is ok, I understand that a peripheral whitelist must be fullfilled with the bond information freshly created. Seems perfect. I suppose that bond must be ko if a central or peripheral random static adress changes. Consequenly, I plan to keep both bond information in the whitelist & original random static keys in flash and reload them at start-up.
Is it a proper way to work? I mean in a secure way.
Thank u again for all your advices.
The best.
Sebastien
