No GPS data on T-BEAM S3CORE

[slash-bit]

Hi,
I got T-BEAM S3CORE board, which originally came with SoftRF. Was working fine with GPS and FANET radio seen on the COM port.
I flashed it with PlatformIO (VS-code) after cloning this git repository into vs-code.

[platformio]
default_envs = T-Beam-S3Core

[env:T-Beam-S3Core]
extends = esp32_base
build_flags =
${esp32_base.build_flags}
'-DENV="T-Beam-S3Core"'
-DSH1106G
-DAIRMODULE
-DBOARD_HAS_PSRAM
-DBLUETOOTH
-DS3CORE
-DARDUINO_USB_CDC_ON_BOOT=1
board = esp32-s3-devkitc-1
board_build.mcu = esp32s3
platform = espressif32 @ 6.3.2
board_build.partitions = 8mb_spiffs.csv
upload_port = COM[4]

The board is working and output in COM Monitor looks like this:

$PFLAU,0,1,0,1,0,0,0,0,0*52
$LXWP0,N,,,,,,,,,,,*6D
$LXWP0,N,,,,,,,,,,,*6D
$LXWP0,N,,,,,,,,,,,*6D
$LXWP0,N,,,,,,,,,,,6D
$PFLAU,0,1,0,1,0,0,0,0,052
$LXWP0,N,,,,,,,,,,,*6D
$LXWP0,N,,,,,,,,,,,*6D
$LXWP0,N,,,,,,,,,,,*6D
$LXWP0,N,,,,,,,,,,,*6D

But I don't see any GPS sentences there. LED is not blinking.
I can connect via Web interface. Also board connects to XC Guide via Bluetooth.
Could you please point me in the right direction?
Thanks

I suspect I have found an answer after some digging around.
T-Beam-S3Core comes with two versions of GPS - Ublox chip or Quetel-chip L76K.
I have the second one. L76K chip works with TinyGPSPlus library, if I flash with example sketch.
But I believe TinyGPSPlus is not included in GXAirCom ?
I see mention of setupQuetelGps(void) but I can't figure out how it meant to work.
