Problems with ANT+ Key

[chgrund]

Hi,

i found this very helpful example project.

since the nRF24AP2 is no longer available, I bought the nRF24L01. I hope that the code also with this module.

I have registered with thisisant. and have the keys ANT+ network key, ANT-FS key, Garmin Developer key, Public network key....

Which is the ANT_SENSOR_NETWORK_KEY and which is the ANT_GPS_NETWORK_KEY?

Over Serial Monitor a get the Messages:

ANTPlus HRM Test! Setup. ANT+ Config. ANT+ Config Finished. Setup Finished. Received RTS Interrupt.

but no Heart Rate data...

(Heart Rate sensor is working and is 20cm away)

Thank you...

Best regards, Christian
