Ratings and reviews

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!

It works but everytime I exited the app, the configuration that I changed were reset so that's really annoying.

This is an invaluable app for debugging BLE software issues. Please join me in supporting the developer so it will continue to be updated. Dev: I would be happy to give feedback on future releases if needed. Leave a reply here and I will email you.
