    I need help in implementing a use case with LoRa SX1278 operating at 433MHz. I want to send a signal to another LoRa/RF receiver when an even happens WITHOUT using any microcontroller/Arduino. For the event, there is already a sensor which works like a relay - normally open, normally close and neutral. I want to send a signal, whenever neutral gets connected to NO or NC. The receiver can be LoRa but I would prefer a normal 433 MHz receiver. No specific message text is required for communication, only the receiver should be able to differentiate with two type of singal for NO and NC.

    I am working on a project that utilizes HART PROTOCOL for communication. My aim is to develop a Hart Transmitter + Receiver that works as a Master, sends data to the existing devices and read back the data. At present I am using DS8500 + AD5421 and PIC Microcontroller and we are facing issues which we couldn't figure out where the problem is. I want someone who has knowledge in developing and testing Hart Protocol who can have a look at our circuits, existing working circuits and guide us around to fix errors. More information about the issue we are facing will be shared when an interest is shown.

The nRf interfaces via UART to a secondary microcontroller (uC1) that will control it. This is what I need done. 1) Send a text message to a specified number and respond to uC1 if it was successful. 2) Report signal strength 3) Report errors and attempt to resolve them. If unable to do so, return an error code to uC1 4) Generate a list of possible errors 5) Code needs to maximize battery life. 6) provide me instructions on how to program the device I can provide schematics. As for development, we will have to discuss what to do about the hardware. Thank you.

    Goal: design a new PCB including part selection, BOM, board design, coding, debugging. Design to use UL listed components and design layout. Designed PCB: Using a microcontroller to control the output state of a solenoid, opening, and closing it when certain inputs are met. The solenoid will open (inject) and close on a schedule of 2 minutes on and 2 minutes off a selected number of times & schedule of days. Ex, on and off cycle repeats 10 times, every other day. There will also be a pressure switch which will need to be closed in order for the solenoid to open, if it opens the scheduled solenoid would stop. Components: - Microcontroller (Preferably AT Mega 324A or AT Mega 168) - LCD Display (NHD-C12864LZ FSW-FBW-3V3) to show the current setting as well as the state of:...
