I wouldn't buy a "real" Saleae though. Insanely overpriced these days. You can buy clones for literally a 50th of the price.
I does still feel overpriced if you ask me. You can get a full Bluetooth Analyser with actually advanced software (I mean there's a huge difference between writing a protocol analyser for SPI or I2C or typical things that run on them, and Bluetooth) for like £1k.
But I guess it one of those things that is aimed at people who aren't using their own money so they make the most money by charging enterprise prices.
The clones are a copy of the Saleae units from 10 years ago. They’re not at all comparable to the current high-end ones.
One of the killer features of the current ones is the ability to also record an analog trace. It’s fantastic when you need to record minutes of something that misbehaves electrically every once in a while.
