Personal Area Network
Description
This command sets the 48-bit unique identifier for the Bluetooth device.
3.13.8 Radio Interface
Table 105 shows how to connect the XE1413 radio chip to the SX1441.
3.13.9 HCI UART
The host processor communicates with the Bluetooth Sequencer through an UART identical to the one described
in paragraph 3.12. The register map for this peripheral is given in Table 106.
Flow control is enabled at all time for the HCI UART. Upon start-up / reset, the HCI UART is configured for 115’200
kbits/s, 8 bits, no parity.
3.13.10
As shown in paragraph 3.5.9, the Bluetooth sequencer is clocked by SYS_CLOCK_OUT and SLW_CLOCK_OUT.
Both must fulfill the Bluetooth specifications. They are usually generated by the radio chip.
