nRF proprietary RF - Actual/practical maximum throughput

[Ros]

Hi,

What is the practical maximum throughput of nRF proprietary protocol? The following table showing ESB and GAZEL has 1.3Mbps and 128kbps respectively.

Thanking You,

Hi,

 

Gazell can send a payload every 2nd timeslot, where the timeslot can be down to 600 us (which means 1200 us per packet) for 32 byte payload:

1000 000 us / 1200 us = 833.33 packets over 1 second = 32 * 833 * 8 bit = ~213 kBit/s. This is theoretical and assumes no collision or lost packets on-air.

 

For nrf_esb, 1.3 Mbit/s is reasonable. You can get closer to the on-air data rate if you disable ACKing, but then you do not know if the receiver actually receives anything.

 

Kind regards,

Håkon
