SimpliciTI data rate CC1200

Other Parts Discussed in Thread: SIMPLICITI, CC1200

Hello,

What's the maximum achievable data rate in SimpliciTI using the CC1200? The radio is capable of up to 1.25Mbps speeds but will SimpliciTI be able to handle that rate? Since Preamble and Sync will not be transmitted at that speed, what is the maximum achievable data rate assuming you're maxing out the buffer with payload?

Can the data payload be split across multiple packets with only the first packet carrying the majority of the header bytes?

Thanks,
Juan

    Hi

    First of all, SimpliciTI was designed to support low rate networks and never optimized for high data rates.  As far as I know it has never been tested with data rates above 250 kbps.

    You can off course test with higher data rates, but you then have to go through the code (mrfi) and make sure that all data rate dependent variables are changed. It is not possible to divide the packets so that the headers are sent first and then the rest of the data is sent in a second packet.

    What you can try to do is to increase the packet size since it was set due to the FIFO size of the first radios supporting SimpliciTI (64bytes). The CC1200 has a FIFO that is128 bytes and this can probably be utilized.
