Has anyone attempted to send RUI3 AT commands to the RAK3172 (STM32WLE5) internal radio SPI bus with an onboard application rather than across the external UART link? Is this even possible?? Seems silly to have to connect up another processor to communicate with the STM32WL, as the STM32 is large enough to hold all application code.
Has anyone attempted point to point communication using LoRa (for instance a long distance RF remote that can communicate to 5-10 nodes on a single network)?
I would like to use the AT commands that are provided but not at the expense of tying up a UART port on the device. It seems logical that the AT commands that RUI3 sends to the device get received within the UART and then sent over an internal bus to the radio. I would like to just be able to summon what AT commands I want within my application and send them to the internal radio on the STM32 rather than having them come in externally…Make sense??
That makes no sense. The internal radio is not working on the base of AT commands. It is controlled through an internal SPI from the MCU to the transceiver with commands and register settings.
Of course I already know that an internal SPI transfers the commands sent over UART to the radio…I would like to hardcode in firmware the AT commands as I see fit and feed them to the RUI3 firmware which then sends these to the radio…
I don’t want to have an external connection to another processor over UART. It makes absolutely no sense to me to build up a very small radio / sensor and have TWO controllers on the PCB, one for the application and one for just communication to a radio…Especially when the radio processor is an ARM32 that is quite capable of holding ALL the application code.
