Prepaid Electric Meter Coding

@TheElitePro

Hi, 1. I understand you need firmware to develop Bluetooth-enabled prepaid electricity meter, supporting balance tracking, remote top-up, and usage history logging with a reliable, user-friendly workflow. 2. I have experience in DLMS protocol, Smart Meters, embedded systems, BLE communication, and solution architecture including secure data handling, real-time tracking, and device-to-app interaction. 3. Relevant experience: a) Developed NXP based Smart meter DLMS implementation over Modbus. b) ESP32-based system with WiFi communication for device configuration. c) Battery powered STM32 and BLE enabled Vibration sensor. 4. My approach: a) Design core logic for balance tracking. b) Implement usage logging (timestamped records, efficient storage) c) Develop BLE services for Balance read/update, Usage history retrieval etc. d) Provide simple interface hooks for display/app integration 5. Deliverables: a) Clean embedded firmware (ESP32 or target MCU) b) BLE communication protocol definition c) Data storage + retrieval system d) Documentation for integration and testing 6. I focus on robust, tamper-resistant logic and stable communication, critical for prepaid systems. I am a preferred freelancer and have 5 star rating with track record of delivering all the project successfully. All this has resulted into repeat customers. Let's connect to define the first task and start date. Regards, Vishal

Hello I will deliver a reliable prepaid meter firmware by structuring secure balance logic, efficient BLE communication, and fail-safe data handling. Confirmations: -Balance tracking with real-time update and display sync -Secure remote top-up via Bluetooth (validated transactions) -Usage history logging with timestamped records -Stable BLE communication (low power + reconnect handling) Approach: -Modular firmware (metering, storage, BLE, UI separation) -Non-volatile storage for balance & logs (power-loss safe) -Lightweight BLE protocol (custom GATT for commands/data) -Error handling for invalid top-ups & communication drops Delivery / Scope: -Clean, documented firmware (MCU-based) -BLE command structure + mobile integration guidance -Test cases (top-up, consumption, edge conditions) -Support for bring-up and debugging Need to clarify: -Target MCU / platform -Metering IC or sensing method -Mobile app side (existing or needed) I can share similar embedded + BLE project samples on request. Regards, Nichita.
