This is a basic question but it taken my time for a while since I do not have enough knowledge in this area.

Recently, I am investigating about functionality of a wifi and bluetooth chip RS9116N-SB00-B00 from redpine. On the chip, there are four RF pins:

  • RF_PORT1
  • RESET_N
  • POC_OUT
  • POC_IN

according to page 9 of the datasheet.

and

Bluetooth and wifi

according to page 3.

My questions are:

  • What does POC (Power On Control) mean?
  • What is RF_BTTX and when to use it?
  • Why in the figure, host interfaces and peripherals are separated? How are they different?

  • \$\begingroup\$ That is a "System on Chip" (SoC) device, which means that it contains a complete computer and operating system in its own right in addition to the specialized communications hardware -- which makes your questions far too broad for this site. \$\endgroup\$ – Dave Tweed Jun 7 at 0:05
  • \$\begingroup\$ @DaveTweed, Thank you Dave. Does it use AT commands for communication? I'm not sure stackoverflow be a better option too. \$\endgroup\$ – alex Jun 7 at 0:07
  • \$\begingroup\$ @DaveTweed, A small part of the question is about communication. Still most of the question is about low level pins. Asking multiple question for each pin seems wrong too. \$\endgroup\$ – alex Jun 7 at 0:08

    \$\begingroup\$ You're right, neither of those are viable options. This is so far outside your level of skill and experience that it's difficult to advise you. I would recommend working with existing COTS (commercial, off-the-shelf) USB-to-WiFi modules -- learning what they can do and how to talk to them -- before trying to build your own. \$\endgroup\$ – Dave Tweed Jun 7 at 0:15
