3. HARDWARE FLOW CONTROL Flow control refers to the control of data flow between the host and the CL2510 It is the method used to handle data in the transmit receive buffer of the CL2510 interface and determines how data flow between the host and the CL2510 is throttled Often in serial communication one device is capable of sending data much faster than the other can receive Flow control allows the slower device to tell the faster device to pause and resume data transmission Flow control CTS and RTS are used by the CL2510 and its Host locally NOT over the air Therefore one CL2510 cannot tell the other to slow down or speed up The transceiver uses CTS to indicate the state of its input buffer The OEM host uses RTS to indicate when it s able to receive data from the transceiver When RTS Enable is set on the transceiver the transceiver will monitor RTS and will only transmit data out the serial interface when RTS is low For this reason the OEM should not set RTS Enable on the CL2510 unless the OEM host is specifically controlling RTS Leaving RTS high for too long with RTS Enable set can cause data loss once the transceivers transmit queue fills Design Tip Can implement a design using just Txd Rxd and Gnd Three wire Interface Yes However It is strongly recommended that your hardware monitor the CTS pin of the radio CTS is taken high by the radio when Its interface buffer is getting full Your hardware should stop sending a

Broadcast packets on to the OEM host ADDRESSED PACKETS An Addressed Packet Is one that is only sent to a specific transceiver based upon the MAC address of the destination Addressed packets are acknowledged by the receiving radio so additional Transmit Retries will only be used if necessary The transmitting radio will retry sending an Addressed Packet until all of the Transmit Retries have been used or until it receives a successful acknowledgement from the receiving radio COMMAND MODE Command Mode is used to configure the transceiver To enter Command Mode on the CL2510 the OEM host must send the AT Enter Command string AT Once in Command Mode all data received by the radio over the serial interface is interpreted as command data Data received over the RF interface will be stored in the TX buffer until Command Mode is exited When using the Laird Technologies Configuration Utility the OEM doesn t need to worry about entering and exiting Command Mode as the software will do that automatically These details on Command Mode are pro vided for OEMs manually configuring the radio Design Tip Entering Command Mode A properly formed Enter AT Command string must be issued when the RX Serial buffer on the radio is empty If data is either pre pended or added to the AT string the radio will not properly identify it as the AT Enter Command Mode command and will not enter Command Mode It is suggested that the OEM host wait a
