ANT Forum

Hi,

We made software to control some trainers. It works fine using the ANT+ USB2 dongle.
Now we use ANT+ USB-m dongle, and noticed that receiving works ok, but sendburst (0x72) does not seems to work.

Is there a difference in using the sendburst between usb2 dongle and usb-m dongle?

Best Regards,

Hi Klaasjan,

0x72 is for explicitly sending "Advanced Burst Data". Advanced bursts are only supported on newer devices such as the USB-m or the nRF5x SoC series. You should continue using the 0x50 to ensure backwards compatibility with all ANT devices.

Hi Harrison,

with ANT+ USB2 dongle the sendburst uses &H48; as command code. This works fine.
with the ANT+ USB-m dongle i got a lot fails.

so it seems that the 0x72 works ok with and USB2 dongle.

This sounds like it could be related to the wireless performance of the devices. Have you tried repositioning the USB-m closer using a cable instead?
