RPi gateway

[hyer]

Hi,

I have two Raspberry Pies and two XRF R001 radioes. My setup is like this:

One RPi reads air quality values from a SDS011 particle sensor and sends the data to the other RPi via radioes. The receiving RPi decodes the data and continuously uploads it to my web-database.

Now, at some point I would like to add more nodes and it would be very convenient if i could get use the the receiving RPi as a gateway to all the nodes. My idea is to be able to configure (e.g update or reprogram) the node RPies through the radio connection.

Do anyone know if this is possible and by any chance have some guidance to how I could do this?
Any help would be much appreciated:)

Just to be clear. The only RPi with a wifi dongle is the gateway RPi.

Just from a quick once over of the documentations, it looks like that is a serial module with an AT command set interface. I think you're stuck with 1 TX'r and 1 RX'r per connection, I don't think you'll find (with this product at least) a 'muxer' for lack of a more intelligent term that would allow multiple transmitting stations with a single receiving station.

Is that the direction you were going, or did I miss the concept?

There is a command mode option for setting the radios to node-mode and master mode. So that shouldnt be a problem. What i would like is to be able to controll all of the nodes from the backbone. Configure them wtihout hands-on work.

Hello Hyer,

Did you make any progress connecting the SDS011 to the rpi? I intend to do the same however have to start from scratch. Can you help me further? In the endI need to log all the data ultimately with wind direction included....
