Hello,
I made easy project with uart communication MCU-> ANTAP281M4IB, but something is wrong :(
My Garmin Edge can't find ANT+module as cadence sensor. Do you have any idea ?

"MCU->a4 3 42 0 10 0 f5"
"ANT<-a4 3 40 0 42 0 a5 "
"MCU->a4 5 51 0 12 34 79 1 ae"
"ANT<-a4 3 40 0 51 0 b6 "
"MCU->a4 1 4b 0 ee"
"ANT<-a4 3 40 0 4b 0 ac "
"MCU->a4 9 4e 0 0 0 0 0 0 0 0 0 e3"
"MCU->a4 9 4e 0 0 0 0 0 0 0 0 0 e3"
"MCU->a4 9 4e 0 0 0 0 0 0 0 0 0 e3"
"MCU->a4 9 4e 0 0 0 0 0 0 0 0 0 e3"
"MCU->a4 9 4e 0 0 0 0 0 0 0 0 0 e3"
.

every 0.5s

"MCU->a4 9 4e 0 0 0 0 0 0 0 0 0 e3"

Hi,

I'd recommend taking a look at page 21 of the ANT Message Protocol and Usage document, as well as the ANT+ Bicycle Cadence Device Profile. You must transmit using all of the correct parameters:

ANT+ Network Key
ANT+ RF Frequency
ANT+ Bike Cadence Channel Period
ANT+ Bike Cadence Device Type
ANT+ Compliant Extended Device Number

Cheers
