Using CC2541 in network processor mode, I am sending notifications for a while, receiving the appropriate "CommandStatus" response, then I stop receiving responses.
This time, before it stopped responding, I received: "04 0e 04 01 28 00 01". Can somebody help me decode it? It looks like a HCI_Command_Complete_Event, with NumHCIBuffers = 1, Opcode = 0x2800, Status = 1. But there is no opcode 0x2800 or 0x0028! What triggered this event?
