ANT Forum

I've written software to communicate with a PowerTap SL+. The Power and Torque data pages are coming through correctly, but the Calibration pages I get seem to be of unknown type. Here's an example calibration message I receive:

01:02:ff:00:74:a5:00:00

byte 0 == 0x01 signals calibration data. byte 1 should indicate the calibration ID as per the ANT+ Bike Power spec, but there's no CID 0x02 listed.

Anyone know what I'm hitting here? Thanks in advance.

I will look into this...      

Any luck?      

you are correct in that calibration ID = 0x02 is not supported in the device profile. i recommend contacting the manufacturer directly. We will also follow up with them.      

I confirmed with the manufacturer that the generation 2 powertap is not fully compliant (from a calibration perspective) with the ANT+ device profile.
