* For the nRF51 Dev Kit, use `make BOARD=nrf51_pca10028` and `./flash_nrf51_10028.sh` with the nRF51 kit.
* The nRF5 dev kit acts as an LE HCI Controller with H4 interface.
## Renesas Electronics
Renesas currently has 3 LE-only SoCs: the older 16-bit RL78 and the newer RX23W and the RA4W1.
For the newer SoCs, Renesas provides a pre-compiled HCI firmware as well as an HCI project for their e2 Studio IDE.
The HCI firmware needs to be programmed into the SoC Flash.
Both newer SoC provide the newer Bluetooth 5.0 features like DLE, 2M-PHY, Long Range, and Multiple Roles.
To install the HCI Firmware on the [Target Board for RX23W](https://www.renesas.com/us/en/products/software-tools/boards-and-kits/eval-kits/rx-family-target-board.html):
* Download [Bluetooth Test Tool Suite](https://www.renesas.com/eu/en/software/D6004348.html)
* Install [Renesas Flash Programmer](https://www.renesas.com/tw/en/products/software-tools/tools/programmer/renesas-flash-programmer-programming-gui.html)
* Follow instruction in [Target Board for RX23W Quick Start Guide](https://www.renesas.com/us/en/doc/products/mpumcu/apn/rx/013/r20qs0014ej0100-23wtbqsg.pdf) to flash `rx23w_uart_hci_sci8_br2000k_v1.00.mot`
**BD Addr** fixed to 74:90:50:FF:FF:FF. A Windows tool in the BTTS suite allows to set a public Bluetooth Address.
**Baud rate**: The baud rate is fixed at 115200 resp. 2000000 with the provided firmware images. With 2 mbps, there's no need to update the baudrate at run-time.
**BTstack integration**: No special support needed.
## STMicroelectronics
STMicroelectronics offers the Bluetooth V2.1 + EDR chipset STLC2500D that supports SPI and UART H4 connection.
