I have a custom made board with STM32F07 chipset and with UG95 and L76-M33 peripherals. I would to ask you, if somebody can enliven it. The board should read the input, read data from the GPS and send an HTTP request to the server. I programming it in STM32CubeIDE with Stlink but only what I did was turn on gsm module and some leds. If you are interested, contact me for detailed information.
