Sorry for the delay in my response. You can find the electrical specification for the Radio RX mode here

Hello,

thank you for the response.

One more question how much is the consumption of the radio part when the device is in Rx ?

Regards,
Riccardo

[quote user="alleghe87"]are any Nordic protocol suitable for that application ?[/quote]

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.

[quote user=""]3) What development kits do you recommend to develop Tx and Rx side ? Do I need 2x nRF52 DK ?[/quote]

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.

Hello,

I do not want to use BLE in THIS application (as explained in the previous question). I need to transfer few bytes at the lowest latency possible, are any Nordic protocol suitable for that application ?

Also as asked to question 3, how is the best develop boards setup to develop both TX and Rx sides ?

Regards,

Riccardo

[quote user=""] 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.[/quote]

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.

[quote user=""]1) Is it possible implement my requirements on those chips ?[/quote]

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

[quote user=""]2) Are you recommended any different chip ?[/quote]

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.
