how to interpret Peak Strength value?

[jamcinnes2]

Using the distance detector, I see strange values for the peak strengh measurements. Sometimes I'll see 3 or 4 or 7 for example. But other times I get values like this 4294959 or 4294959.

What are the units? Could it be a signed integer or float being misread?

Hi @jamcinnes2 -

I'm about to do a little work on. this library and saw this issue and the related PR.

From the A121/XM125 documents it looks like the strength measurements are in dB. As I see the PR, the value is being interpreted incorrectly - I agree that it should be an int32_t and not divided by 1000.

I'll get this fixed as part of the small code refactor I'm doing over the next week.

This is fixed, with the updated code in the develop branch. This should be released/published once we publish the upgrade to the SparkFun_Toolkit library (which this library uses) - 1-2 weeks...
