The PAN1780AT is a Bluetooth® 5 Low Energy Module based on the Nordic nRF52840 single-chip controller. The Bluetooth® 5 features enable a higher symbol rate of 2 Mbps using the high-speed LE 2M PHY. Furthermore, the new LE advertising extensions allow for much larger amounts of data to be broadcasted in connectionless scenarios. The PAN1780AT comes with AT Command Stack by BlueRadios.

Some features of the AT Stack

  • Bluetooth 5.0 support – 2Mbps and Long Range PHY support, extended advertising packets, LE Secure Connections pairing.
  • Up to 8dBm output power now supported.
  • BlueRadios Serial Port throughput up to 50kBps.
  • Single mode modules can now be connected to 5 devices simultaneously (1 as a peripheral and 4 as a central).
  • Configurable MTU up to 247 bytes.
  • USB and NFC support.
  • Dedicated Over the Air Firwmare Update (DFU) service. Firmware updates no longer done through BlueRadios Serial Port service.

The PAN1780AT uses a proprietary GATT profile developed by BlueRadios to stream data; it is not an official Bluetooth profile. BlueRadios serial port implementation simplifies the user experience, allowing users to stream data similar to the way the official Bluetooth Serial Port Profile (SPP) works on BR/EDR devices.

Low Energy Protocol Stack

Stack details

The Bluetooth Low Energy protocol stack is built similarly to the Bluetooth Classic stack, with a controller layer at the bottom, followed by a host layer, and finally the profile and application layers. The GAP and GATT layers and above are the only layers where only the user takes care of. The GAP layer controls device discovery, advertising and connections. The GATT layer handles the exchanging of data. The PAN1780AT countains a full stack all the way up to the application layer as seen below. The AT Application Programming Interface (API) contains all the necessary commands to enable the user to quickly and easily develop a fully-featured Bluetooth Low Energy application.
