    I need to Pass BLE280 sensor readings (Temperature, Humidity, Pressure) to Arduino Nano and further via Modbus RTU RS485 (I use SCM TTL interface module to connect to a PLC that is acting like a Modbus Master ). The readings from the BME280 are float numbers and thus the Holding registers must be accordingly.

    I'll try to summarize as much as possible what I want and if you have any questions just ask me. I would like to develop a hardware, basically I want to create a gas sensor using an Esp32. This would be the first part of the project, the second would be just an app to visualize this data, alerts in case of leakage, that would be very simple. I want to solve is precisely to make it commercial, for example: To be able to develop a system that is multi-user, where the customer who buys my gas alert system can register this sensor in the app and have access the aforementioned information. Summarizing what it would be: Develop pcb for this gas sensor system, app for the customer to register the device and the "backend" so that this idea of ​​several users on the platform works...

    I have a simple teensy sketch. I have supporting schematic and hardware. I have compiled to best of my knowledge but I am doing something wrong. I am trying to put together but somehow cannot seem to get it working. I would like someone to guide / assist me in what I need to do to get the project working. I would also like someone to modify the code to port from a teensy to esp32/8266. For a professional this will be easy work. For me I don’t have the attention span. I am confident with soldering circuitry and simple code. But I am not a c+ nor a micropython expert. So I require the services of someone who is competent in arduino, teensy, c++, python and circuitry / pcb.

    We wish to build up on and use one of these existing projects. This is a basic 'credit' management system for users, where they swipe a card and credits are taken off, it is logged and there credit total is adjusted. BASIC outline of what we are wanting to achieve. User will - swipe a card - handshake with server - check if user has credits available IF ---- YES - Output a signal on the one of the ESPXX spare pins momentarily. - Reduce users 'rolling credit' on 'server', saving ID of ESPXX device. ---- NO - Alert user with message on screen to see an 'ADMIN'. On the links above, software / programming / general setup etc exists. So most of the 'hard work', has been done. Modification of front end and back end as required to dis...
