Hi Dan, I was also using a wireless system for measuring suspension acceleration, if you change from BLE to Bluetooth classic then you should be able to increase your throughput. I was able to record data at 850Hz using this method to an Android Phone, I did need to mess around with data packets and the Bluetooth library buffer sizes...

The reason I chose MEMS accelerometers was because they are cheap and widely available, and telemetry systems using displacement sensors already exist, things like MotionIQ. What I wanted to develop was something a little different to what is currently available, would be easy to package, would be cheaper, and the system could be scaled to be simplified and reduced in...

Sure, I use a ESP32 and an ADXL357 accelerometer - I have gone through a lot of hardware to get to this choice. I just use a standard smart phone for the data acquisition/analysis side of things, seems to be man enough for the job.

I have just stumbled on this thread.... I also had a lockdown project of creating a suspension telemetry system. I used a slightly different approach. I used 2 units each containing a MEMS accelerometer connected to a micro controller (image below of the 2 units). One mounted at the handlebars and one mounted on the brake calliper. I then logged...
