ANT Forum

Hi,

I'm currently studying the behaviour of burst transfer, but I rather confused about the channel configuration.

Q1. For the transmitter end, how many channels do I have to configure? 1 or 2? (Eg. Channel 0 for TX, channel 1 for RX OR simply channel 0 for TX will do)

Q2. Similarly, for the received end, how many channels do I have to configure? 1 or 2? (Eg. Channel 0 for TX, channel 1 for RX or simply channel 0 for RX will do)

Q3. If I need to configure 2 channels on both end, must the frequencies be different?

Q4. Must I open all the channels on both ends?

Thanks.      

To handle burst transmissions, on both ends, you only need to use one bidirectional ANT channel. For the "transmitter" end, you would configure a bidirectional master channel, and on the "receiver" end, you would configure a bidirectional slave channel. Note that since the channel is bidirectional, both master and slave can send and receive data, and either of them can initiate a burst transmission.      

Thanks for your reply.

I just realized I was reading the outdated ANT protocol Rev 2.1.2, which contains an error in the configuration for Acknowledged data type, page 21, between node A & C.

It's stated they are using 2 different frequencies to communicate, which I now believed is wrong since the latest document Rev 3.1 has corrected this mistake.
