Now, this is getting even more strange; consider the following HCI Tester script, run against a CC2540 USB dongle running the factory firmware:
Send_GAP_DeviceInit 8, 3, 0, 0, 1
Send_GAP_EstablishLinkReq 0, 0, 0, "44:57:6E:E5:C5:78"
Send_GAP_TerminateLinkReq 0
It produces this output:

So, "EstablishLinkReq" returns bleAlreadyInRequestedMode, even when called immediately after a GAP_DeviceInit !
How do I reset the CC254X using the software commands?
