Which method is recommend for BLE security?

[MarcoTull]

Hi,

I am wondering which is the best method for BLE security to avoid MITM, protect the data (sniffers) and limit connection only to allowed devices for a massive number of BLE devices, example 500 > random and new devices.

Peer manager is the recommend for this task? or something like Application-level Security Using the ECB Peripheral?

Hi Hung, I was wondering how can I enable "LESC pairing with Just Works" what settings are required on peer_manager_init?

sec_params.bond           = SEC_PARAMS_BOND;
sec_params.mitm           = SEC_PARAMS_MITM;
sec_params.lesc           = SEC_PARAMS_LESC;
sec_params.keypress       = SEC_PARAMS_KEYPRESS;
sec_params.io_caps        = SEC_PARAMS_IO_CAPABILITIES;
sec_params.oob            = SEC_PARAMS_OOB;
sec_params.min_key_size   = SEC_PARAMS_MIN_KEY_SIZE;
sec_params.max_key_size   = SEC_PARAMS_MAX_KEY_SIZE;
