Re: [bluetooth-dev] Develop application



Hi Raymond,

When used as a module,  the data flow for received ppp frames packets in the
Axis stack is something like this:

(bt device) -> bt_receive_lower_stack -> hci_receive_data ->
process_acl_data ->
  l2cap_receive_data -> rfcomm_receive_data -> bt_receive_top ->
(/dev/ttyBTx)

As you can see, your ppp frames are passing through l2cap and rfcomm before
they
reach the ppp layer.
