    In this project we want to rename and change setting of a hc05. PIC - 18f26k22. 1 x HC05 for internal com. 6 x push buttons. idea is that i will connect a brand new HC05 to location. then i will press one of the 6 push button. based on the selection, it will change HC05 name etcs. for example. original HC05 - name - HC05 password - 1234 baud rate - 9600 after selecting PB 1, it will change it to name - MAGNETDOCTOR password - 1234 baud rate - 115000 and so for the next 6 switches.

    I had to remove the previous project because I described it too vaguely and there were many inquiries. I have such a problem, namely I would like to go straight from point A to point B with my boat. The boat is steered by two engines. I have tried many things but unfortunately I am too weak to comprehend it. The boat is flowing like a sine wave (). I am looking for a person who would help me understand how to correctly calculate the data for the boat to go straight, i.e. the shortest route between points A and B. The code in Arduino is enough for me. Any platform: Arduino, STM32, ESP32 The current code that I use for testing is attached. I tried to use the compass, the boat hits the target perfectly but unfortunately it flows in a curve () I have time to complete the project by Octob...

    I am looking for a freelancer who can code STM32F0 series microcontroller in STMCube IDE Key Requirements of Code: -> The code should contain parts which can make MCU to communicate with Quectel BG95 module -> MCU should use Multi UART communication The MCU should use a UART connection to connect with one external device (ex. datalogger), the mcu should wake up once per day from sleep and communicate with the external device by sending some commands. The external device after receiving commands from MCU will respond back with its own responses, the received responses should be sent to the Quectel BG95 module using another UART connection, finally these responses should be sent to google cloud.

I need help removing any redundant functions that are not being used, and creating a library with all the remaining functions. This will alllow the file to be less cluttered as it will call its functions from the library file. The ESP32 firmware controls a device with an ADXL accelerometer, an optional GPS unit, ethernet or wifi connectivity, LEDs and a buzzer. After starting up its peripheral devices it checks if ethernet is connected, if not it uses Wifi with Smartconfig protocol, then connects to AWS. This is done using AWS certificates stored in the SPIFFS memory. Once connected to AWS it collects the ADXL FIFO buffer of accelerations every second and sends them t...
