Low latency RF 2.4 Ghz transceiver

[alleghe87]

Hello,

I'm new on Nordic environment, I'm designing a RF module that require low latency to transmit few bytes (less than 10) in less then 10ms from a triggering input (i.e pin interrupt). The target range is about 50-100m in open air.

After some research on the website I chose nRF52805 or the nRF52832 because in future I'd like to use the same chip in different application such BLE mesh.

My questions are :

1) Is it possible implement my requirements on those chips ?

2) Are you recommended any different chip ?

3) What development kits do you recommend to develop Tx and Rx side ? Do I need 2x nRF52 DK ?

Kindest regards,

Riccardo Stragà

10ms latency upto the range of 50.100m can be difficult on BLE, but this depends on how much throughput you are expecting. There will be packet losss at those distances so you might have to use proprietary solutions to achieve that low latencies at those distances.

1) Is it possible implement my requirements on those chips ?

You can use those chips to achieve your requirements using some proprietary protocols but difficult with BLE and BLE Mesh

2) Are you recommended any different chip ?

nRF53 based chips are more powerful in terms of processing power and this will make sure that your protocol and application pre and post processing are done faster. Also having a dedicated Modem for any protocol is always an advantage. But this is not the right place to suggest or recommend you which chip suits your requirement. It is best that you reach out the Regional Sales Manager in your area. I can inform him to reach you for your convinience.
