CC1101 for gateway

[orrpan]

Adding new hardware CC1101 would be awesome!
SpaceTeddy has an library for rpi and arduino on github

Hello,

On my side I'm not familiar with this radio ic. Perhaps some people here but not sure..
To make it compatible with Mysensors that would need someone here have the hardware for it, and get some time to do a PR on this. I've checked the code just a little bit, that would need some refactor, but we can't do this without testing.

That said, actually we use RFM69 radios in Mysensors for these RF bands (433 to 915Mhz). There is also RFM95 available for LORA mode.

Okey to bad

Good range, low price 😃

How many do you need for testing?

@orrpan adding support for a radio to the library is one, maintaining and supporting it over a longer period of time is a whole different story.
I totally agree with @scalz. The library already supports a popular, proven radio, so there currently is no need to support others.

then i rest my case :hammer: :smile:

First off, sorry to revive this.

I just discovered the (new?) 8-pin CC1101 modules and thought "hey, it uses the same socket as the NRF24".

So I tried comparing the pin positions. And to my surprise they seem very compatible:

GND -> GND
CE -> GDO0
SCK -> SCK
MISO -> MISO

3.3V -> 3.3V
CSN -> CSN
MOSI ->MOSI
IRQ -> GDO2

To me this radio would have a few advantages over the RFM69:

• Plug and play. I could plug it into the Nano wireless expansion boards.
• Built in antenna socket.

I think it could be advantageous to use a 433 radio that is plug-in compatible with the NRF24 in this way.

• 3D printable cases and open hardware designs would only need to support one socket design and still support both frequencies.
• The STM8S103F3P6 (the "1$ arduino") has a version with built in socket, and expressly advertises that it is compatible with both radios. There is an STM32 version with a socket too.

As someone who started by using the NRF24, I've long wished I could easily switch to the 433Mhz band instead. Supporting the CC1101 would make that as easy as plugging in a new radio.
