ANT Forum

Hey I'm developing a sensor network using ANT shared channel. Here are my set up:

1) I'm using a Android tablet as master. The app was modified from aquired channel app from sdk.
What I did is
- Modify the ANT config so it is ANT shared channel
- Loop a broadcast from adress 1 - 5 in the Channelhandler when channel event is TX
2) For the sensor I used a nRF51422 system which config to send two broadcast data back to master in every 5s period.

3) the channel freq is 4*5=20hz, I put a delay about 1s after set broadcast on sensor side. And I used a shared slave channel

Here is the problem, I'm experiencing a huge data lost of the broadcast data from master.

Any ideas?

Thanks in advanced for your help!!

     

Are you using ANT built-in to the tablet or an ANT USB stick? If you are using ANT built-in, WiFi and Bluetooth share the radio with ANT and may cause packets to be dropped as they must split radio time with each other.

What channel period are you using? 20 Hz should look like 1638/32768 s. Your shared slave channels will also filter out messages which do not fit it's shared channel address.

Cheers
