Comments on BLE Tool for Android

★★★★★ Sergio Juarez · Aug 13, 2020
Amazing app. No need of fancy ui if you want the real raw bytes when you're testing.
★★★★★ wirelessad4 · Feb 16, 2024
Thank you for providing greate apps!! One question and request. This app is not displayed on android 14's play store. Can you explain why? And could you display this greate app on android 14's play store? Thanks
★★★★★ Rakesh Kumar · Mar 14, 2019
"Unable to scan nearby advertising device (server)." Now I am able to scan in samsung phone. There is issue with Motorola phone.
★★★★☆ Doncho Antonelli · Mar 30, 2022
This app is great! It is the ONLY solution I have found that allows me to create a BLE server from my phone so that I can test my BLE client code. Only issue I see thus far is that I can't seem to write new values to the BLE server characteristic, but I could just be using it wrong. If this is an open source project, I would love to contribute!
★★★★☆ Luke Senseney · Mar 6, 2022
Kinda hard to use, but it's about the only (free) tool that does what it does, and it does work.
