AB-01 V2 RGB led indicator

#1

simple code doesn’t work on AB-01 V2 (v2.2 on PCB - version with etched label on cap) - onboard LED just keeps in off state:

#include "LoRaWan_APP.h"

#ifndef LoraWan_RGB    #line 3
#define LoraWan_RGB 1  #line 4
#endif                 #line 5

void setup()
{

}
void loop() {
  turnOnRGB(0x500000,100);
  delay(1000);  
  turnOffRGB();
  delay(1000);  
}

but it works on AB-01 V1.2! moreover - it works even if I set LoraWan_RGB 0
or even if I comment lines 3,4 and 5.
it also works if I change first line to #include "LoRa_APP.h"

this code has been checked for both board version with Arduino IDE ( Heltec CubeCell (ASR650X) Arduino Support V1.5.0)
and PlatformIO ( latest platform - Heltec CubeCell v 1.1.0 which the same release V1.6.0 - https://github.com/HelTecAutomation/CubeCell-Arduino/releases/tag/V1.6.0)

but for example, this code - works on both boards with both IDE:

#include "CubeCell_NeoPixel.h"

CubeCell_NeoPixel pixels(1, RGB, NEO_GRB + NEO_KHZ800);

void setup() {
// put your setup code here, to run once:
pinMode(Vext,OUTPUT);
digitalWrite(Vext,LOW); //SET POWER
pixels.begin(); // INITIALIZE NeoPixel strip object (REQUIRED)
pixels.clear(); // Set all pixel colors to ‘off’
}

void loop() {
pixels.setPixelColor(0, pixels.Color(255, 0, 0));
pixels.show(); // Send the updated pixel colors to the hardware.
delay(500); // Pause before next pass through loop

pixels.setPixelColor(0, pixels.Color(0, 0, 0));
pixels.show(); // Send the updated pixel colors to the hardware.
delay(500); // Pause before next pass through loop
}

I dont understand - why it is?

second code just pretty the same code which is executed if I include LoRaWan_APP.h and run turnOnRGB
