I am using a Transceiver nRF24AP1 (
http://www.sparkfun.com/products/8565) with an Arduino board, and I am trying to communicate with a heart rate sensor.
I have not been able to receive data from either an HRM or a simulated one from the ANT+ Sensor Simulator software (with a Garmin ANT+ usb stick). I can set up and open the channel, but it always times out during search.
However, I can use the same device to perfectly emulate an HRM and receivng the data with the ANT+ display simulator software on my PC.
Below is the complete log of communications with my ant transceiver when trying to connect to the ANT+ sensor simulator. the same code with just the modification of the channel type (to 0x10) when assiging the channel and correct channel Id setup works perfectly for transmission.
I have tried using/not using wild cards for the assign channel, using other sensors, changing period or network key...
Does anyone have any idea what the issue could be ?
thanks a lot for any help available
