Sending from master to slave on the same device

Hello,

For technical reasons about our chip, we need to implement some kind of "keepalive" service on a ANT+ device. So I had the idea of using 2 channels, one for transmitting and one for receiving messages on the same device.

BUT, using ANTWare II or SimulANT+ i'm not able to receive any message from the same device.

e.g:
On ANTWare II:
- Device A: Channel 0 - Master - Device Type 125 - Device Number 33 - Auto-Open
(Starts broadcasting 00-00-00-00-00-00-00-00)
-Device A: Channel 1 - Slave - Device Type 125 - Device Number 33- Auto-Open
(EVENT_RX_SEARCH_TIMEOUT... EVENT_CHANNEL_CLOSED)

Is this possible or is a software filtered issue?

Thanks,

You cannot implement the master and slave side of a channel on a single radio (single usb stick). This is because the radio can only receive, or transmit at one instant in time. You need to have master and slave on different USB sticks.
