Connecting BLUENRG-M2SA to a Raspberry Pi

[bifftannen]

Hi,

I want to conenct the BLUENRG-M2SA to a Raspberry Pi. This needs to be done through the USB connector.

Can I use a USB-to-UART IC to connect to the UART pins of the BLUENRG-M2SA and then flash the software using this?

Also, do I need to connect the reset pin to the Raspberry Pi, when I flash the software.

Thanks.
