Software / GCS Support
The software solution is an open source development called "SiK". It has been re implemented to suit the new processor architecture available on the 32bit ARM processor core. A boot loader and interface is available for further development and field upgrade of the modem firmware via the serial port.
Most parameters are configurable via AT commands, Eg. baud rate (air/uart), frequency band, power levels.
Integrated support for configuring the RFD900 radios is supported by APM Planner.
The default settings are at 57600 baud, N, 8, 1, and 64k air data rate.
The RFD868/900x manual is here: RFD900x Manual
The RFD868/900x SiK software manual is here : RFD900x Peer-to-peer Manual
Software features include:
- Frequency hopping spread spectrum (FHSS)
- Transparent serial link
- Point to Point, or Multipoint networking
- Configuration by simple AT commands for local radio, RT commands for remote radio
- User configurable serial data rates and air datarates
- Error correction routines, Mavlink protocol framing (user selectable)
- Mavlink radio status reporting (Local RSSI, Remote RSSI, Local Noise, Remote Noise)
- Automatic antenna diversity switching on a packet basis in realtime
- Automatic duty cycle throttling based on radio temperature to avoid overheating
Compliance
The RFD868 is designed to be compliant with the following standards:
- FCC Part 15.247 (Frequency hopping and digitally modulated intentional radiators)
- AS/NZS 4268:2012 (Radio equipment and systems - short range devices)
The modem is designed for system integrators who will integrate the modem into their own projects and product prototypes. The user is responsible for compliance with local regulations for radio transmitters.

Best pillow protector ive ever used!
Size: Body
I was afraid this pillow protector would inflate with air like every other pillow protector I've ever used (from super cheap to super not cheap). Man was I wrong! You can't even tell it's on the pillow and it doesn't take away from the squishy goodness of the pillow. I love these body pillow protectors so much I've ordered 5 so I'm never without! I also use their regular sized pillow protectors and it's the same exceptional quality. Coop home Good's outdid themselves with this one and I couldn't be happier. Body pillows are expensive and this is a good way for me to protect my investment without sacrificing any comfort! LOVE IT!
UPDATE: I've been using these for a few months now and they're just as soft now as the day I put them on. But I have finally given in to the fact that they're a tad troublesome getting on and off. When I first got them I washed them often and line dried (these take a long time to dry, you have to flip them inside out over and over to get them fully dried because the inside will hold the water from the washing machine). However over time I've found myself washing them less frequently because it takes all day to get them dry but also because I'm always nervous the zipper will break during put ons and take offs. You are supposed to squish your pillow into and out of the opening which obviously is very possible but there's no way to avoid putting stress on the zipper opening during this process. Another thing about these protectors is that the greyish strip along the sides is NOT water proof. So everytime I do take the protectors off i find new stains along the sides where the pillow had no protection. And I could be wrong but I think the non-water proof gusseted sides are an essential to the extreme comfort of these protectors so I can't be too picky (otherwise I believe these would inflate with air anytime pressure is applied). If I didn't have young children I probably would've never even realized the sides aren't waterproof. I would still take the coop Home Good's pillow protector with non water proof gusseted sides over the average pillow protector ANY DAY.

Good pillow protector
Size: Queen Size (Pack of 2)
Looks and feels very durable. Didn't notice and odor when opened or in use. Fits my Coop Home Goods pillow perfectly! Sleep quality is still good with these covers on.

Very nice but expensive
Size: Queen Size (Pack of 2)
I love these cases, they didn't let out as much air as I had hoped for out the sides so I only zip it up half way so my pillow stays squishy and moldable and not partially filled with air which changes the feel of your pillow. Other then that they are great, they are very soft and quite, there is no noise whatsoever and there is some thickness to it adding a little more softness to your pillow. I ended up buying a second set. I just wish it had a little more airflow through the sides so I didn't have to leave it unzipped, that kind of defeats the purpose. I also think they are a little more expensive then they should be.

Does not change the pillows effectiveness at all.
Size: King Size (Pack of 2)
As of right now, I have not noticed anything with these covers that would significantly alter the way the pillows feel. I'm greatful that they are not noisy as most other covers are. I also appreciate that they have very much the same feel as the covers that come on the pillows. One thing I can say so far with confidence is that even though this is an additional layer to my pillows, the original feeling, specially with the Eden cool+, has been the same in terms of coolness and breathability.

SUPER SOFT - GREAT QUALITY!
Size: Crescent Queen
This crescent pillow protector is more than I expected, as far as softness and just the overall quality of it. I wish my PILLOW was as nice as this protector! Definitely recommend.
