nrF51822 gazelle enhanced shockburst

Tom Russell

What is the difference between Gazelle and Enhanced Shockburst on the nRF51822? Is one faster or more energy efficient?

Thanks, Tom

    Hi Tom,

    Both ESB and GZLL is based on the same framework in nRF51x22, so their performance is very similar. GZLL has a top layer, which also includes frequency hopping/frequency agility to ensure a stable RF link, which again may give a lesser performance due to re-transmissions (when sync'ing transmitter and receiver.)

    ESB is a bit more simple, where it handles auto-ACKing under-the-hood, and it communicates on a static RF channel (no hopping) If you look at the nRF24L01+ datasheet, you can read more about the ESB protocol and how it's built up.

    Best regards Håkon
