If you can see packets being transmitted (for example, check with SDR radio) then there is a problem with decoding (another device should transmit proper ax.25 ui packets and use the same LoRa modulation parameters).
If packets are not transmitted then there is a problem with pinout definition. You need to select "Heltec WiFi LoRa32 V2" in Arduino Tools -> Boards menu and make sure your board flavor has the same pinouts as defined in ~/.arduino15/packages/esp32/hardware/esp32/1.0.6/variants/heltec_wifi_lora_32_V2/arduino_pins.h
Check that MOSI, MISO and SCK are correct for your board
30 static const uint8_t SS = 18;
31 static const uint8_t MOSI = 27;
32 static const uint8_t MISO = 19;
33 static const uint8_t SCK = 5;
Also, it would be nice to see what is printed out to console log.
Hi @emsieg be aware that this FW uses ax25 and kiss frames, so it won't be decoded by other igate like the one from github/lora-aprs and the sh123 tnc in server mode won't decode lora-aprs tracker. Also be sure to test with
it when using the ttgo lora32. As sh123 suggested, do you have a sdr to check if your lora32 is sending anything ?

Hi, may I ask for some help?
I´m not able to TX/RX any APRS packets via antenna. I see, the board is connected via WiFi to APRS Server and is sending beacons to the server. But, no RX or TX via antenna is possible.
I´m using a Heltec WiFi LoRa32 V2 board and defined
define LORA_RST 14
define LORA_IRQ 26
define SS 18 (I have added it later as I thought it could be the issue as
no definition is shown)
I put my other iGate next to it, testing any TX and also my Tracker , testing any RX.
I have installed different SW and see with that SW, I´m able to RX/TX any LoRa packets, so HW is not defect.

If packet was received, but ax.25 decoding failed then Skipping non-AX25 payload
log line should be visible in the console log. It is possible to send such packet to APRS as is assuming that it is text based submission, so that incoming packets from text based trackers could be gated.
Hi, I installed a SDR SW on my laptop for testing. here I see, that the Heltec is sending something OTA. This packet get not been recognized on other Lora devices.
I also see that packet received on my tracker, but this heltec igate is not working with that.
Console.txt
I have added 2 screenshots, Heltec iGate -12 is sending, Tracker -11 is sending and Console
thanks for helping
@emsieg , looks like LoRa module is initialized and packet is sent out. What are other devices where you are trying to receive this packet? Are you sending from -12 and expecting to receive on -11 and vise versa? Are other devices where you are trying to receive packets based on this project and/or support AX.25 UI frames?
Hi, -11 is my tracker, which is only TX -10 is my other iGate which is only RX -12 is the new iGate with digipeat enabled, this now device)
I expect to see -12(this Lora) to be seen in display on -10 during -12 TX; just like -11(tracker). when the tracker (-11) is sending, i expect it to be seen it in display on -12.
I powered-off -10(iGate) to see, if -11(tracker) is forwared to APRS.fi, but did not.
it looks to me as i send something on -12, which in incompatible to the other Lora devices.
@emsieg , what are other LoRa devices? Which firmware is used there? Do they support AX.25 UI frames or they send plain text messages?
