X4

Used only with Totem X4 module to enable all functionality and on-board features:

  • Implements all X4 module functionality.
  • Makes X4 module discoverable over Bluetooth.
  • Provides direct access to TotemModule functions (Totem.X4.write("indicate")).
  • Enables passthrough to communicate with external modules connected over TotemBUS.
void setup() {
  Totem.X4.begin(); // Initialize X4 interface
}

Disabling Bluetooth

By default X4 module makes itself discoverable over Bluetooth in order for mobile applications or other modules to connect and control it. This functionality takes a lot of space in flash memory and increases compile and upload times. If this feature isn't needed, Bluetooth can be disabled with custom initialization call Totem.X4.beginNoBluetooth(). This reduces compiled application size and allows faster development.

void setup() {
  Totem.X4.beginNoBluetooth(); // Will utilize 50% less flash memory
}
