Hi, I have a new project where I will need to make a wireless link between a few devices around a 20 meters perimeter. The protocol can be a simple master/slave protocol and should not be a problem to code. The hard time I am having is selecting a wireless chip that I can make to work with little RF knowledge and that I can buy easily in small quantities. Data speed is also not a big problem as I can live quite well with 19200 bps troughput. So far the best option I have found is the Nordic NrF240L01.. Can you guys point me to some other inexpensive and easy to interface parts ?
