TEMPE Battery Level

DaveBrillhart over 2 years ago

It is a shame that Garmin doesn't profile ANT+ profiles for HR Straps and TEMPE sensors.

My TEMPE sensor arrives today. I'm adding code to grab temp data to my data field for this device.

I'd also love to grab the battery level. But "THIS IS ANT" also doesn't document this sensor's pages.

The generic Env Profile doc doesn't explain where battery data might be in the set of pages this thing sends.

Has anyone deciphered the pages and found if/where it sends battery level?

Thanks!

I checked a couple of watches where I have the tempe paired natively, and none of them show battery level on the Tempe. The Tempe is kind of different when it comes to sensors. For one thing, it transmits 24/7, unlike things that only transmit when being worn/used. The temperature data gets updated once a minute. Because of the 24/7, I'm guessing the transmissions are probably lower power.

That said, with a tempe, the battery for me lasts about a a year

Thanks Jim! Good idea to check the sensor stats using Garmin Connect Mobile... I forgot about that feature. Great way to see if sensor battery data is available. Interesting that it stays alive 24/7. A year is great.

Curiously after over 30 mins, I actually did get a Battery Reading. But all the other stats are null. Weird.

Data page 82 contains the battery status which is documented in the ANT "Common_Data_Pages_Rev_3.1" document. You can check how to retrieve the Tempe battery status in the "Tempe Field" data field source code: https://github.com/maca88/TempeField/blob/master/source/TempeSensor.mc#L90
