_BRB_L2CA_PING structure

Description

The _BRB_L2CA_PING structure describes a request to ping a remote radio.

Members

`Hdr`

A BRB_HEADER structure that contains information about the current BRB.

`BtAddress`

The address of the device that the ping is sent to.

`PingRequestLength`

The length, in bytes, of the data to send in the ping signal.

`PingRequestData`

The data to send in the ping signal.

`PingResponseLength`

The length, in bytes, of the data that the remote device responded to the ping signal with.

`PingResponseData`

The data that the remote device responded to the ping signal with.

Remarks

To ping a remote radio, by transmitting a L2CA_EchoReq message and receiving a L2CAP_EchoRsp message, profile drivers should build and send a BRB_L2CA_PING request.

BRB_L2CA_PING is primarily used for debugging.
