Do I need PA.BOOST on CubeCell?

HarryS · September 12, 2022, 6:12pm

I am familiar with using the Heltec ESP32 WiFi LoRa 32 dev board and I’m now doing my evaluation of the CubeCell HTCC-AB02. For the ESP32 board, one had to turn on PA.BOOST to enable power levels >14, up to 17. Is that the case for the CubeCell? If so, how do I do so?

NOTE: I am not using LoRaWAN.

You can use this program to test the transmit power.

HelTecAutomation/CubeCell-Arduino/blob/master/libraries/LoRa/examples/LoRaBasic/TxPowerTest/TxPowerTest.ino

#include "LoRaWan_APP.h"
#include "Arduino.h"

#define RF_FREQUENCY                                868000000 // Hz
#define TX_OUTPUT_POWER                             20        // 20 dBm
#define TX_TIMEOUT                                  10        // seconds (MAX value)
static RadioEvents_t RadioEvents;

void OnRadioTxTimeout( void )
{
    // Restarts continuous wave transmission when timeout expires
    Radio.SetTxContinuousWave( RF_FREQUENCY, TX_OUTPUT_POWER, TX_TIMEOUT );
}
void setup() {
  // put your setup code here, to run once:
  RadioEvents.TxTimeout = OnRadioTxTimeout;
  Radio.Init( &RadioEvents );

  Radio.SetTxContinuousWave( RF_FREQUENCY, TX_OUTPUT_POWER, TX_TIMEOUT );
}

The configuration function of the PA is SX126xSetPaConfig.
