Re: [bluetooth-dev] ask about send_cmd and send_cmd_block


If my understanding is correct, it is like this:

1. All the commands which trigger peer to peer communication (one BT
device to other), use send_cmd(). The blocking if needed in this case is
taken care by the upper layers, depending upon the senario.
2. If the command triggers some communication only between the local
host and the kit, (like read bd_address, read buffer_size etc) then
blocking is the responsibility of HCI layer and use send_cmd_block().

Someone correct me, if I am wrong!
