Issue with log window

There is an issue with the log window, when transmitting a BLE packet it will show “Wrote Value 0x(null)” in the log window…instead of the actual data that was transmitted. This needs to be fixed.

Also, copy & paste doesn’t seem to work using keyboard shortcuts (CMD+C, CMD+V) - neither in the log window nor in the input field where TX data is entered. This should be an easy fix as well.

Otherwise, quite useful app. Just needs more / consistent testing before release, otherwise these very basic issues would not have slipped through. How does this reflect on the company (“seller”)?


Good tool for bluetooth low energy sensor development

This is a solid, basic tool that was able to pinpoint a problem in a bluetooth low energy communication link. Big help in determining that a BLE112 development board was working, and that the problem was in my data format. The write services in hex or ascii are key for troubleshooting. Used on a 2011 MacBook Air with integrated BT 4.0 where the built-in bluetooth software had not been discovering my low energy BT devices.



I lost my Fitbit and was able to sync, so knew it was in or near the house. I searched without luck and then read a recommendation for this app. I installed on my iPhone and the signal started upstairs and increased as I moved downstairs, outside, and to the car. This app worked like a champ - found the lost Fitbit in the car!
