About this app

Measure RSSI strength of nearby Bluetooth Low Energy (BLE) devices. Connect to them to get a list of Services and Characteristics on the BLE device. Read and write to Characteristics and Descriptors.

• Six modes to choose from: Levels, Graph, Meter, List, Report & Read/Write.

• View RSSI on a graph, gauge or in a list.

• Average, Maximum and Minimum RSSI.

• Auto-scale, or touch scaling/panning of graphs.

• Write ASCII, Hexadecimal, 32-Bit Integers or Floats to Characteristics or Descriptors.


Note that this app is for Bluetooth Low Energy (Bluetooth 4.0), and will not work with Bluetooth Classic (Bluetooth 2.0).

The app does what it says on the tin. It does scan BLE, and generate graphs and charts well. Sometimes ill have to restart the app if started with the Bluetooth radio off. but the biggest annoyance for me is a lack of basic features like filtering by signal strength, most of what shows up is -90+ and makes looking for a specific device a headache as there will be tens of entities that are on the bare edge of being detected. This is a 5 star app, but I have docked it two untill filters get added.

Lost Fitbit found. Tried 4 other apps before this one. This was the only one that actually worked! Easy to use and different meter choices to view signal strength. Picked up my fit bit, wife's fit bit, my TVs and even our cars. Color coding made it easy to differentiate and track down signal and location. Ads on bottom of the screen where not annoying.( I click every ad, thanks Kewlsoft!)

I haven't used this yet, The UI looks useful and Its already picking up devices. For those of you complaining about GPS needing to be turned on...anything that deals with the location of an item now has to utilize GPS per the GOOGLE/ANDROID API. I don't like it either, but it's not the developers fault. (Apple iOS requires the same thing) Even WiFi scanners have to have GPS turned on now.
