Hello all,

With Slave mode, I set timeout for search.
after I open channel, I can receive and send data to master. But when Slave board do not receive and send for a long time (more than timout), I can not receive and send any data.
So, I have a question that: Is it need open or init again when timeout?
Please help me,
Thanks all,      

Hello ngphuthinh,

It is normal for a slave to close its channel after a search timeout. To receive/send data again, the channel just needs to be opened. It shouldn't be necessary to re-configure the channel.

Let us know if this answers your question      

Thanks for help.
How can I config for slave enter mode always open channel?
Or it just support for master mode?      

Not a problem.

If you do not want to re-open the channel for synchronous communication, you could set your search timeout to infinity.

You may also want to read up on the "Continuous Scanning Mode" in the ANT Message Protocol and Usage document, to see if it may be useful for your application. Be aware that this mode will accept data from multiple nodes if allowed to, however.

In either case, an increase in total power consumtion would be expected.      

thanks vary much for help,now I can do it alway open.
