Hello support team!

Please check the specification of the DA14585 about the difference
between the data sheet(DA14585_datasheet_2v2.pdf)
and the design guide(DA14585/DA14586 Application Hardware Design Guidelines V1.0.pdf) .

1)UART Port Pin Assign
It assumes the terminal setting (SPI, UART) of Step A in Table 20 in the data sheet .
For the UART terminal, the difference with the design guides anxious.
In Table 20 of the data sheet,
UART TX: P0 _ 0, UART RX: P 0 _ 1 is stated as Step A (Default?).
On the other hand, in 5.1 of the Design Guide,
UART TX: P0_4 and UART RX: P0_5 are recommended as Default settings when using UART.

2)C8 Specification
Which value should be used for C8 hanging on the VDCDC_RF terminal of the Figure 2 circuit in Design Guide 4?
100nF or 1uF?
In the Figure 2 of Design Guide 4(Page.7), it is described as C8: 100 nF,
but at section 5.4(page.8), it is stated that 1 uF is used.

Regards,
