We were testing with DA14583 with the "IoT Sensors" demo app for a while. When we read the firmware code, we noticed that the accelerometer's data rate can go up to 1600Hz.
We tried sending the signal of 0x09, boosting the data rate of accelerometer to 200hz. It works.
However, when we tried sending the signal of 0x0A, boosting the data rate to 400hz, it does not work. The app could not receive any data from the sensor anymore.
How shall we fix this?
Anywhere in the iOS code that can trigger higher data rate? Or does it have to be done on the firmware side instead?

Hi pureform,
In the IoT Sensors application we support up to 100Hz accelerometer's data rate. If you change the data rate to 200Hz, yes it is working but you won’t completely be sure that you receive all the data that are you sending over the air.

Yes, we are aware of that.
When we change to 200hz, the actual data rate we're getting is around 190hz.
But how do you boost up to 400hz?
Hi pureform,
As I mentioned in my previous post, the accelerometer is able to operate up to 100Hz data rate. You can boost up to 400Hz with the same way that you have already mentioned, by sending 0x04, but it is expected that it isn’t working and if it is working ou won’t completely be sure that you receive all the data that are you sending over the air. So, it is strongly recommended to not boost up the accelerometer data rate, so I suggest you to work with 100Hz and in worth case up to 200Hz.
