CurieBLE: advertising doesn't work with longer local names

[sandeepmistry]

Observed by @CarlaMSedze and @rodriguezcarlos from the Arduino CTC team in Malmo.

#include <CurieBLE.h>

void setup() {
  BLE.begin();

  BLE.setLocalName("Messenger");

  BLE.advertise();
}

void loop() {
}

We expect this sketch to work. As with 2.0.2 both the advertisement data and scan response are supported. I think we should be able to support local name values up to 20 characters ....

Sorry, the sketch to reproduce is actually:

#include <CurieBLE.h>

void setup() {
  Serial.begin(9600);
  while (!Serial);
  
  BLE.begin();

  BLE.setAdvertisedServiceUuid("19B10001-E8F2-537E-4F6C-D104768A1214");
  BLE.setLocalName("Messenger");

  Serial.println(BLE.advertise());
}

void loop() {
}
