APRS TX of Battery Voltage in 'WX_FIXED' Mode? #21

Closed K4KDR closed 2 years ago

K4KDR commented 3 years ago

Just updated to e2077e4, THANK YOU so much for adding pressure to the weather data!

I have been using 'WX_TRACKER' mode so that every-other TX would include battery voltage. But in hopes of prolonging battery life, switched to 'WX_FIXED' mode to turn off the GPS.

I would still very much like to see battery voltage in the telemetry, and discovered:

#define HW_COMMENT // send Alt und Battery Voltage, UNcomment if you want to send it

... so with that UNcommented, I was hoping to see battery voltage in the APRS message.

Unfortunately, while MY_COMMENT text comes through fine, I never see any mention of battery voltage.

Here is how my messages are appearing on APRS-IS:

2021-05-30 14:05:15 EDT: K4KDR-13>APRS,qAS,K4KDR-14:!3746.70N/07736.55W_.../...g...t069r...p...P...h59b10223_433.775 LoRa APRS + WX

... am I missing a step, or not understanding the proper use of HW_COMMENT?

For reference, when I was using 'WX_TRACKER' mode, the battery voltage was reported perfectly under SSID 'K4KDR-4'.

Thank you VERY much for any assistance!

One follow-up...

In the serial monitor, I notice that battery voltage IS reported in this config. So, no issue there but of course it would be wonderful to see it via APRS, too.

((TX)) / LAT: 3746.70N / LON: 07736.55W / No GPS used / SAT: --- / BAT: 4.2 / TEMP: 20.6 / HUM: 58.6
State: Packet sent!

I found how I could add the battery voltage to my APRS "Comment" when using mode = WX_FIXED and am happy with the result:

2021-05-30 22:19:52 EDT: K4KDR-13>APRS,qAS,K4KDR-14:!3746.70N/07736.55W_.../...g...t071r...p...P...h58b10257_433.775 LoRa APRS + WX -- Batt=4.18V

thank you for playing around with my code which I wrote during the x-mas holiday season in Dec 2019 - it was planned to be the base for other APRS operators - so this happened and I am very happy about that :-)
