read and write in the same time #26

Is it possible to implement the read and write operations in the same time?

For the moment when I am trying to read some data and in the same time to send something, the write operation occurs only when I receive something! Thx

rfm12 is half duplex. You can either send or receive. If multiple units send on the same frequency you would only read garbage, like two people talking at the same time. For full duplex operatoin get a second rfm12.
