Low latency RF 2.4 Ghz transceiver

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

    are any Nordic protocol suitable for that application ?

    Yes, you are most likely to achieve that using ESB or Gazell within our solution. In both cases, your application take most of the control of packet transmission so pre and post processing of packets can have reduced latencies.

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

    Not sure if i understand your question correctly. TX and RX can work on the same radio but not simultaneously. If you want Full Duplex radio not time multiplexing,

    If time multiplexed TX and RX on one device is ok, then one DK would be enough. This is the working mode for most of the protocols.
