Hello Christian,
In advance I was able to show you that the T-Beam did boot up in "Tracker / WX mode". Terminal data did show that, and indeed the WX broadcast did pop up in APRS.fi. Unfortunately the Tracker broadcast does not show up anymore. It does show up when I set Tracker mode to 0.

So:
PA1SDB-9 tracker is silence
PA1SDB-8 WX transmits every 15 minutes.

#define DONT_USE_FLASH_MEMORY
#define TRACKERMODE 1
#define CALLSIGN "PA1SDB-9"
#define WX_CALLSIGN "PA1SDB-8"
#define LONGITUDE_PRESET "0651,18E"
#define LATIDUDE_PRESET "5319.14N"
#define APRS_SYMBOL ">"

An option would be great to use the chosen APRS_SYMBOL with normal callsign while using WX-Tracker Mode and use only WX SSID and WX symbol while using WX_Move and WX_Fixed

Just found this multisensor board, would be nice to implement it into software.

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!

Hi, I was wondering about the on-the-wire-format of LoRa packets containing APRS.

It looks like this code is generating the header, consisting of:

• verbatim "<"
• sender's ID (byte) - is that ever initialized anywhere?
• 0x01 byte

What is the meaning of the "<" and of the 0x01? It looks like the regular LoRa header is four bytes (to, from, ID, flags) - why is the APRS header shorter? Why are we not using to=0xff (broadcast)?

Hi, i got plenty of T-Beam around, and i'm wondering if it's possible to attach more the one DS18b20 probe like we do on ESP Easy.
Either on different Gpio nor same one as a daisy chain (1Wire)
I need to monitor several temps around the Node .

Thanks in advance

Hi, When I set Tracker mode setting to 1, 2 or 3 it boots up in mode Tracker (=0). Set #define DONT_USE_FLASH_MEMORY on or off has no effect. It boots in Tracker mode (no WX). Only when I push the middle button on my V1 T-Beam (no Oled) for 10 Seconds I see it switching (in the terminal screen) to WX-Tracker and WX report becomes visible in APRS.fi. But when I restart the T-Beam by plug in the power, it boots up in Tracker mode (no WX).

(PA1SDB-7 iGate - PA1SDB-9 mobile - PA1SDB-8 WX)

Hi, is it possible to decode the received coordinates and show them in the displaytext?

Hi, by using GPIO 4 the onboard LED can be used for TX LED and an external LED can be connected, too. Rev. 1

Hallo Christian, ich habe nur eine kleine Änderung, damit es ein paar weniger warnungen gibt...just refactoring
TTGO_T-Beam_LoRa_APRS.zip

Dear Christian,
I try to flash some of the new T-Beam boards with the new Powerchip.
All boards not working anymore.
They hang up while try to TX.
Any idea whats the issue?
