Before the app allows you to connect to the bike, it requires you to link your mobile phone and receive a code. Unfortunately, the phone verification server for the app was shutdown, so there is no longer any way to link your phone, and therefore no way to access the rest of the app (since the phone linking is on the first screen) The app is quite proprietary so i believe there must be some way to simply bypass this portion of the app and be able to access the rest of the app abilities without linking a phone number The unmodified apk is attached. Please review it and let me know a reasonable cost to complete thi...

Please look at the pictures with this project and read the text file. Please list some projects that are similar to this one. This could be a long term project, but we will start slow and see how you work in our environment. You will be remoting into our system, and using remote debugging tools. This is part of a larger project that uses a tablet via bluetooth, that connects to a gateway via XBEE to control a 3 axis robot. You can see details at We will ask technical questions right away to determine your background for this project, This is our custom board and you will have to work remotely with the board. We have developed a new "transceiver" board based on the NRF52840 chip that utilizes both bluetooth and XBee communication. Half...

When I have a Bluetooth headset connected notifications come through the earbuds. However, I usually don't have my earbuds in so I don't here them. I need an app that will make the notifications chime through the phone speakers even when the Bluetooth headset is hooked up. I can find apps that will make the phone ring through the speaker but not the notifications. My old phone I could turn earphone mode off and it would work but this phone does not have that option. I have an one plus 10 pro international phone.

Briefing The app is being developed to access information from an ESP32 device, which has a water flow sensor. ESP32 records water consumption and the app presents this data in the form of a bar graph. At this stage of the project, I need to implement the initial configuration of the ESP32 device using Bluetooth, as the link (), in addition, implement the MQTT to access the ESP32 device via MQTT Broker on the internet and the redesign of the screens. I developed the app's initial flow to make it clear what the app needs to check once it's started by the user, after that it's simple, the app already knows the ESP32 device via mDNS or MQTT Broker, with that, the app must do HTTP GET/POST via mDNS on the local wi-fi network, or via request/response topic
