Inter packet delay cc2511

Other Parts Discussed in Thread: CC2511, CC2510

Hello,

Is it possible to define or calculate the inter packet delay while sending a burst ??

I know it is possible to do it on Smart RF Studio, through the packet interval field. which mentions that the default value (150 ms for CC2511) is calculated based on the packet size and data rate. I couldn't find any information on it in the datasheet, however.

I would like to know how to control the inter-packet delay if I'm writing my own code/protocol. and how to calculate it for CC2510/11.

Thanks in advance !

    Hello Ami,

    Look at Table 16: Frequency Synthesizer Parameters  in the data sheet. There you have all the times for start up, calibration and turnaround time for switching between TX/RX. You can send packets at a much faster interval than 150 ms. The reason it is used in SmartRFStudio is because of the duration of the processing time for the actual computer software and device communication.The "Packet Interval" is not a radio setting, it is a configuration option for the SmartRF Studio software.

    You will need to calibrate the PLL initially and at regular intervals or for every packet. Also read section 

    13.17.2 "Frequency Hopping and Multi-Channel Systems"  to know how to reduce calibration time when using frequency hopping.
