*** Requires a corTalk® uGI1 to use. *** Contact us at 'sales.ugi1@mobiltex.com' to purchase. This app is for configuring the uGI1 (Micro GPS-enabled Interrupter 1). The uGI1 is used to monitor and control a cathodic protection rectifier by switching a relay at precisely scheduled intervals. This app allows access to basic information on the uGI1 and allows setting up 10 different profiles to meet the customer's needs. Note that logs, due to their size, can only be extracted from the uGI1 using the PC configuration application through the USB port. The app has three tabs, a 'Settings' tab, 'Profiles' tab and 'Live Profile' tab. The 'Settings' tab allows for seeing a detailed status of the device, any recent faults that have arisen, manually setting the Real Time Clock (RTC), setting the unit's name, adding notes and rebooting the device. The 'Profiles' tab allows for the custom configuration of up to 10 independent profiles. It can read/write them from/to the unit and set their values. In addition, the profiles can be reset to their default values. The 'Live Profile' tab gives real time live information on the uGI1 Profile. The uGI1 must initially be put in Bluetooth pairing mode and a pairing code entered on the app. The pairing code (default=123456) can be found and changed with the PC configuration application. Once paired, the iOS device can reconnect without needing to re-enter the code or put the uGI1 back into pairing mode. Only iOS devices supporting Bluetooth 4.0 (LE) can connect to the RBT1 with this app. (iPhone 4S and newer and iPad 3rd gen and newer)

nRF Connect for Mobile
Reported bugs
4 issues- Can't read data from Bluetooth device
- Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
- Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
- Cant go past the initial announcement. The app is unresponsive to the taps.
