Pushing BME280 Sensor Readings between 2 Argons via BLE

My Argon do show up on the nRF Connect, but cant seem to see the advertised values even with the example from another thread
From Need help sending BLE UART broadcast

#include "Particle.h"

void setAdvertisingData();

float   volt;
float   amp;
float   watt;
float   temp;
uint8_t percent;

void setup() {
  setAdvertisingData();
  BLE.setAdvertisingInterval(130);                  // Advertise every 100 milliseconds. Unit is 0.625 millisecond intervals.
}

void loop() {
  static uint32_t ms = 0;
  
  if (!digitalRead(BTN))                            // use MODE button to reset the dummy data
    ms = 
    percent = 
    volt = 
    amp = 
    watt = 
    temp = 0;
  
  if (millis() - ms < 1000) return;
  ms = millis();
  
  if (percent < 100) percent += 5;
  volt    += 1.5;
  amp     += 2.5;
  watt     = volt * amp;
  temp    += 0.5;
  
  setAdvertisingData();
}

struct customData {
  uint16_t companyID;
  char     data[25];
};

void setAdvertisingData() {
  int                retVal = 0;
  customData         cd;
  BleAdvertisingData advData;

  cd.companyID = 0xFFFF;                            // undefined company ID for custom data

  memset(&cd.data, 0x00, sizeof(cd.data));
  retVal = snprintf(cd.data, sizeof(cd.data)-1, "%.1fV%.1fA%.1fW%.1fF%u", volt, amp, watt, temp, percent);
  Serial.printlnf("%s (%d)", cd.data, strlen(cd.data));
  if (retVal < 0 || sizeof(cd.data)-1 < retVal) {
    strcpy(cd.data, "too long! press MODE");
  }
  advData.appendCustomData((uint8_t*)&cd, 2 + strlen(cd.data));

  BLE.advertise(&advData);
}

Not gonna discount the possibility that the issue lies with iOS nRF Connect. But I do not have an Android device available. Ideally, I should advertise and receive on another Argon that can can serial print out the received payload.
