CC1350: ED and Rs connectivity

Part Number: CC1350

Hi TI,

i'm interested to know the RAM & Flash sizes requirements if the total data size of one bundle of sensor data is 200 bytes and the time stamp is 3 hrs setting. 

We will collect all the sensor data in every week schedule for this system. Could you share with me the calculation?

Thank you.

    Hello,

    The answer to your question depends on your application. Which 15.4 mode you're using, what features you have enabled, etc.

    I'm a bit confused, are you planning on receiving 200 bytes of data every 3 hours for one week? If so, you have 8 samples per day, and 7 samples per week, which means you'll have 56 samples totaling 11.2 kB of data. This does not include the overhead of each 15.4 message, by the way.

    I encourage you to build our sensor/collector examples to get a baseline of available flash and go from there. Again, depending on your application you may or may not have enough flash space for this.

    Here's a link to the SDK for the 1350: https://www.ti.com/tool/SIMPLELINK-CC13X0-SDK.

    Yes my BLE sensor nodes will be keeping 200 bytes of data at every 3 hours in RAM and send out once a week. 

    The communication protocol is bluetooth. Does the calculation of total memory sizes that you shared previously is 11.2kB based on my details elaboration?  

    Thanks.

    Hey GOT,

    Thanks for clarifying.

    The calculation I made was strictly based on the information you provided and is not specific to any protocol. The protocol affects the amount of available space you have left on your device. What I said can also be applied to Bluetooth.

    I encourage you to build our bluetooth (simple peripheral) examples and get a baseline of available flash. You can view the .map file for flash usage and see how much flash is available for your application.
