I have tried to interface zigbee module with cy8c21434,s RX8 and TX8ws . when I send any caommands like AT, ATI , etc through TXSW to zigbee , Then Zigbee gives response to controller. I cant get full character in RX8 which is from zigbee module, For example When i send AT command to zigbee module, i want to receive OK response from zigbee , But in RX8 i just got K or carriage return. But in wired communication(controller and PC) This setup working properly. In wireless , some character missing, i dont know why?... any one explain me.....
There may be two reasons for overwritten bytes or chars
- CPU speed is too low
- Buffer is not enabled
ZigBee must be sending characters with very less time between characters.
