ANT Burst Mode and Custom Byte Size Transmission

[Jay]

Hi everyone,

I was not able to find a full example in the SDK or online on initializing ANT to work with burst mode. Also, I was wondering if it's possible to setup ANT with custom data byte size.

I am currently using the background scanning example in the ANT folder to send and receive data.

Thank you.

Please visit www.thisisant.com. There you can find such example.

In broadcast/ack msg data size is always 8. For burst data it must be a multiple of 8.

For advanced burst mode, data can be sent in multiples of 8, 16, or 24 bytes instead.

The changes to for example the ant_broadcast are minimal. Just use sd_ant_burst_handler_request() instead of sd_ant_broadcast_message_tx(). The channel must also be birectional to use anything other than broadcast.

Great, thank you. Also, in the ant_broadcast example, two channels are open: one for tx and one for background rx. Does rx require any changes to receive burst messages?

[Petter Myhre]

The RX channel must also be bidirectional.
