CC2640R2F: Moving nodes speed limit to pair BLE devices

Inigo Kamiruaga
Prodigy 10 points
Part Number: CC2640R2F

Hi,

I would like to use the CC2640R2F modules for moving nodes. However, I'm concerned that the modules will not be able to cope with high moving velocities to communicate or pair among them. If there is a speed limit to work with moving devices, I would be glad to know, thank you.

I'm also wondering about the relation between the transmission power and the range, since there is no information about the range of this module in both urban and outdoor (line of sight) areas.

Thank you in advance,

Iñigo

    Hello Iñigo,

    Unlike mobile/cellular systems, Bluetooth LE is not typically tested under moving velocities so there is no data to share on this topic. Also, since velocity is relative, my best advice is for you to obtain some development kits and evaluate the performance under your application scenarios. We have APIs in our SDK to obtain the packet error rate, so that can be incorporated into your evaluation.

    Range is not a specified parameter and is a function of many parameters, both environmental and device specifics (i.e., link budget). There is a range estimator spreadsheet pinned to the top of the BLE forum. This can help with range estimates based on your specific operating conditions.

    Best wishes
