Custom BLE EV Charger App

I have an AC EV charger that already works through the generic Tuya app, but I now need a fully branded solution. Your first task will be to flash our existing BLE module with custom firmware so it exposes the functions we need. Once the module is ready, I want a companion mobile application built for both iOS and Android.

Module used :CBU-IPEX

The app must connect in two ways: directly over Bluetooth when the driver is standing next to the charger, and over the internet for true remote control when they are away. A single log-in should seamlessly handle both pathways.

Core user commands include:
• start or stop a charging session
• set a current limit on the fly
• switch between instant charging and scheduled/timer modes
• display live battery SoC as reported by the vehicle/charger
• show the energy units consumed per session and over time

A simple, intuitive UI is crucial; think one-handed use while holding the charge cable. Any cloud or backend you select simply needs to be reliable and economical—Firebase, AWS IoT, or your preferred stack is fine as long as it delivers fast round-trip control and secure data.

Deliverables:
1. Flashed BLE firmware image with documentation for future updates
2. iOS and Android builds (App Store & Play Store ready)
3. Source code and build instructions
4. Brief test plan confirming all controls work both via Bluetooth and through the cloud

If you have previous experience with EVSEs, BLE peripherals, or similar IoT apps, let me know; it will help speed things up.
