I have a drone connected via UART to an ESP32 Controller I have connected to the Arduino IDE. I want to ensure that I have successfully established communication with the drone (currently running Betaflight firmware) and would like to send it msp commands to ensure that it is connected properly. How can I go about this?

I tried this sample code:

#include <MSP.h>

MSP msp;

void setup()
{
  Serial.begin(115200);
  msp.begin(Serial);
}

void loop()
{
  msp_rc_t rc;
  if (msp.request(MSP_RC, &rc, sizeof(rc))) {
    
    uint16_t roll     = rc.channelValue[0];
    uint16_t pitch    = rc.channelValue[1];
    uint16_t yaw      = rc.channelValue[2];
    uint16_t throttle = rc.channelValue[3];
    
  }
}

And got this output:
rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

Not sure how to interpret this.
