Forwarding this request on to the list Paid work >From an acquaintance in Brisbane Australia. I *could* do it, having done similar with PIC-controlled RF comms, but I'm just snowed under with other things Anyone who can help, please contact Vince v.niumata@gmail.com -------------------- Vince's request - I have 2 sets of radiometrix RX2 / TX2 sets which have RSSI and can communicate up to 200m at 9600bps. What I need is programming using Netduino , Arduino , or whatever and creating a circuit that works. I know RF is tricky and there needs to ensure the right power, good connections, length of cable runs, antenna selection etc to get the best result. There also needs a radio dialogue between the 2 prototypes, i.e. creating a protocol for messaging with hooks that a RX unit will recognise, then ensuring the correct sync so that the RX unit can read the data sent by the TX unit. There is no 2-way communication so needs to be a listening process --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
