Joe Jackson replied to Patrick Mccabe's discussion Xbee is delayed and sending in packets
"Try the following on both XBEEs Set RR(MAC retries)=0 ,does not sent ACK or wait for ACK when data sent AP(API mode)=0 Transparent mode BD(baud rate)=7 (115200) RO(Packetization Timeout)=0 ,instant transmit of data"
