No callback after calling GAPCentralRole_StartDiscovery in CC2541 Keyfob (I Tested based on MasterSlave Project after modifying)

Hi everyone.

After I tested MasterSlave Project successfully with my CC2541 Keyfobs,

I tried to test scan function of them cause MasterSlave Project initially hardcode MAC address and I don't like it.

After look into "simpleBLEcenteral" Project, I made some modifications on simpeBLESwtch.c.

but it doesn't seem to work as I expected.

sequence :

1. initialize as usual.

2. when key_sw_1 pressed, I called GAPCentralRole_StartDiscovery.

-> after finishing discovery, simpleBLECentralEventCB should be called. (with GAP_DEVICE_DISCOVERY_EVENT in parameter)

but simpleBLECentralEventCB wasn't be called when I tested.

so I wonder how can I make my CC2541 Keyfob to perform discovery properly.

If you know the answer or have same failure, please comment.

Thanks.

    Is it possible that the changes you made broke this? Do you get the callback with the default project?

    I'm sorry I'm not sure I'm fully understand your question.

    Any default project for keyfob doesn't call GAPCentralRole_StartDiscovery.

    Even in Switch project, "GAPCentralRole_EstablishLink" is just called.

    (This means it works well as a "Initiator")

    and I just wanted to test "scanner" function and so far it doesn't work well.

    so is there anyone who tested scanner function in Keyfob?
