Topic: How to connect NRF24L01 to PC without Arduino board (Read 6 times) previous topic - next topic



The question is simple, i have one arduino and two NRF24L01, i need to send commands from PC to arduino with use of NRF24L01 modules. In this case i need to connect one NRF24L01 to PC and other one to arduino, arduino will not connect to PC as it works on battery.
I also have USB To RS232 TTL PL2303HX Auto Converter tool which i don`t know may it help me.

Please tell me can i connect it to PC or what i need to buy as bridge between PC and NRF24L01 ?

I'm designing a USB interface for the low-cost nRF24L01+ modules that are available on Ebay. Here is the schematic:

Thanks for reply Leon,

I want to know the name of this module which you have created and also link to it on eBay. The scheme seems good but I can,t create it with my equipment and also with my current knowledge.

Is it possible to do it with TTL module? It has rxd txd pins can I use them with SPI?

It's really easy to do it with an arduino lilypad or nano on the server side.

Juste power it to the pc with an usb cable and it will works forever.

And with this way of doing you don't have to mind about TTL RS232, because you will be able to comunicate between the pc and the arduino by the usb port as an RS232.

so from you can connect the RF24 module to the pins 9,10,11,12,13 to send the information with this wireless module.

It├ęs really easy to set up this stuff.
