Hello, I will develop the firmware and control electronics for your SolarPump X prototype using the ESP32 platform. I will write the firmware in C/C++, building a secure BLE server profile to communicate with your mobile application and process user-input target pressures. To manage pressure monitoring, I will interface with your analog or digital pressure transducers, using the internal ADC and applying a software-based calibration algorithm to handle noisy signals. I will implement a closed-loop control system that monitors the live pressure readings and automatically drives the inflation motor. Additionally, I will design and document a safe switching circuit using high-current MOSFETs or relays to switch the inductive load of the pump motor while protecting the ESP32 from voltage spikes. 1) What are the exact voltage and peak current ratings of the pump motor we will be switching? 2) Are we using a specific analog pressure transducer, or do you have a digital sensor model selected? 3) Which software development environment do you prefer for the firmware build? I am having ESP 32 in my home lab & have successfully projects based on this Thanks, Bharat

I've been writing production firmware for over a decade, and this ESP32 BLE remote control is exactly the kind of project where experience matters. I've shipped BLE-based control systems on both ESP32 and Nordic platforms, including a real-time motion-to-haptic feedback device where sub-millisecond latency and stable pairing were non-negotiable. I can deliver the firmware, handle the BLE stack configuration, and validate the communication end-to-end. I don't need handholding on the scope or the hardware — I'll get it working and hand over clean, documented code. Let me know if you want to discuss the specific GATT profile and connection parameters you have in mind.

Hi, I can develop the ESP32 BLE firmware for SolarPump X and help bring the smart tire inflator prototype to a working, testable state. The best solution is to build the firmware around a robust BLE server, calibrated pressure-sensor reading, closed-loop inflation logic, and safe high-current load switching. The ESP32 will read the analog/digital pressure transducer, advertise/connect over BLE, receive commands from the mobile side, control the pump/valve output, stop automatically at the target pressure, and report live pressure/status back to the app. I’m comfortable with ESP32, C/C++, Arduino/ESP-IDF-style firmware, BLE services/characteristics, ADC calibration, pressure transducer integration, closed-loop control, GPIO/PWM control, relay/MOSFET switching for inductive loads, debugging hardware/software issues, and prototype wiring documentation. Deliverables will include: * Flashed working ESP32 firmware * BLE connection and command/status flow * Calibrated pressure reading * Closed-loop pump control logic * Safety handling for target pressure and fault states * Tested prototype behaviour * Wiring schematic/documentation * Setup and testing notes I can start by reviewing the pressure sensor model, pump/load specs, power circuit, ESP32 board, and desired BLE command format. Best regards Ankit

@lkrbhavanam

Hi, This sounds to be a nice project. I suggest we go with STM32 as you are saying that you want to run the system via solar-power. The reason is, STM32 consumes far less power when compared to ESP32 and is quite accurate in terms of data with sensors/actuators. If you have plan of going for WiFi functionality as such in the near future, I suggest to go with ESP32. But, as far as I see now, STM32 will be a very good choice. We can go with something like STM32WB. I personally worked with it. The BLE server works great and it has an OTA functionality that STM offers. I would like to discuss further on this and build this for you. Coming to my experience with STM32, I worked with HAL, Bare-Metal and freeRTOS on different STM32 chips. Looking forward to hear from you soon. Thanks & Regards, Lalith.

I'm an italian electronic engineer with more than 20 years of work experience. I work as HW designer and FW developer. As HW designer, I work in KiCad and Altium and I have experience in development single MCU (Microchip PIC, ARM Cortex, ESP32) boards with several digital I/O (GPIO, UART, SPI, I2C, PWM,....) and some analog I/O. I design complete board: power section, MCU section, peripheral section,.... I design also boards with battery power; so I have experience in low power PCB design. As FW developer, usually I work in C for Eclipse + GNU ARM GCC for different ARM Cortex M0/M0+/M3/M4/M33 manufacturers (STM32Fx, NXP, EFM32/EFR32 SiLabs, Nordic nFR5x, but I'm ready to learn new frameworks). I have also good experience with ESP32 in "esp-idf" framework. I work with both single task (baremetal) and multi-task environment (ThreadX, FreeRTOS, RTX,...). I write code for low level driver (GPIO, UART, SPI, I2C, PWM....) management, for medium level (driver for sensor, MEMS, memories, fuel gauge, display,...) and for high level/final application, for bootloader and for OTA. I have great experience in cloud communication with MQTT/MQTTs (FreeRTOS MQTTCore)/AWS (AWS IoT Core)/Azure protocol and HTTP/HTTPs (for SSL I have great knowledge of mbedTLS library). I work also in "C code" commercial boards Arduino/Linux embedded commercial boards (Raspberry and Beaglebone). I have experience in bluetooth (both 2.0 and 4.0) programming.

Hi, I can help with the embedded firmware side of this prototype, especially the BLE/data-flow/control-loop parts. My background is embedded software and middleware integration, including debugging hardware/software data flow, sensor/control paths, and system-level issues. For this project I would structure the work as a small, testable firmware milestone: 1. define the ESP32 BLE service/characteristics for pressure, control commands, and status, 2. implement calibrated ADC pressure reading with filtering and clear conversion points, 3. add a simple state machine for pump control, thresholds, timeout, and fault handling, 4. keep hardware-dependent code separated from BLE/control logic so it is easier to test, 5. provide wiring notes, build steps, and a short test checklist. To be transparent, I would first confirm the exact ESP32 board, pressure sensor output range, pump/valve driver circuit, and whether the mobile side already has a BLE client. If you want a focused first milestone, I suggest starting with BLE connection + pressure readout + documented state machine before final closed-loop tuning.
