Hello Matt,

 Could you check out these similar threads and see if they are of any help?

Are you sure that you have set up the "just works" correctly?

Hi, Martin:

I have searched and checked all the questions in Q&A firstly, but not helpful.

Please check the Sniffer data, the Pairing Response is Just Works's parameters.

Below is my sec_param setting:

sec_param.bond         = 1;
sec_param.mitm         = 0;
sec_param.io_caps      = 3;
sec_param.oob          = 0;
sec_param.min_key_size = 7;
sec_param.max_key_size = 16;
sec_param.kdist_central.enc  = 0;
sec_param.kdist_central.id   = 1;
sec_param.kdist_central.sign = 0;
sec_param.kdist_periph.enc   = 1;
sec_param.kdist_periph.id    = 1;    
sec_param.kdist_periph.sign  = 0;

[Martin Lesund]

sec_param.kdist_central.enc  = 0;

Change 'enc' (Long Term Key and Master Identification) to:

sec_param.kdist_central.enc  = 1;

 

(I would recommend you to use the macros and true/false, instead of just numbers)

Hi, Martin:

I try it before, sd_ble_gap_sec_params_reply() will return error, not response to master.

What does sd_ble_gap_sec_params_reply() return?
