I am new to this and am trying to use NFRT4L01 units to communicate.
I have built two boards and am using simple ping code to bounce a message between two units. I have found it is unreliable. However I can normally get it to work by placing my finger on the end of the antenna (the antennae is internal to the Printed Circuit Board). It seems to be the transmit that is failing (i.e. placing my finger on unit A causes Unit B to start receiving)
It seems that different combinations of chips work better than others, even though they are all supposed to be the same.
Units fail whether they are 2 cms or 10 metres apart, so I am presuming it is not signal strength.
Is there something I am missing? Would I be better using a units with aerials?
