Hi MySensors!
I have some projects in my drawer, let me introduce three of them:
First, it's RF24Remote. It's a driver/library that implements RF24 driver's interface as remote calls from a Linux box to an Arduino device. Connection can currently be via VUsb or via Serial. It's working and tested to some extent, however transfer rate is not best as of now (~4kB/s) and still needs some tuning.
Second, it's Mysensors Linux gateway. It's currenly a bit dirty fork from RPiGateway that utilizes RF24Remote, so it's possible to run it on a generic linux box only with...
... with the third one, and that's the "RF24VUsb Mini stick". It's kind of minimal PCB with VUsb connection via USB-A male, ATMega328p, a LED, ICSP header and nrf24l01 socket. Some pictures:
It's usable for mentioned setup of RF24Remote & MySensors gateway, and also as a MySensors repeater hooked to a USB charger.
I'm currently proceeding with a test run on my MySensors setup with serial gateway on my linux box, so far it seems working fine.
Any opinions/feedback/ideas for improvements welcome.
