[nRF51822] Connectable Indirected advertising after pairing was done.

Jeffery

Hi sir In Desktop 2, before BTLE pairing, nRF51 uses Connectable Indirected advertising. After BTLE pairing with BTLE host, nRF51 will select Directed advertsing for saving connection time. Could nRF51use Connection Indirected advertising type to the BTLE host which was already paired with it? Then, like mouse or keyboard device, can they still work well?

Regards, Jeffery

    In Desktop 2 source code, Bonding information was stored at flash page 255 and System attribute was stored at flash page 253. Then, I made a experiment. Step1. Pair nRF51822 sample A with BTLE host. Step2. Copy flash page 253 and 255 from sample A to smple B. Step3. Modify sample B to have same device address as sample A. Step4. Try sample B to connect the BTLE host directly without pairing. (The BTLE host already had bonding record of sample A)

    The result is frustrating. Sample B still cannot work with BTLE host.
