Hello SparkFun Team,
I am using a SparkFun nRF52840 Mini Breakout with an STM32 Nucleo-L433 connected via UART .
I want to send data from the STM32 over UART and have the nRF52840 transmit it wirelessly, similar to HC-05 / HM-10 transparent Bluetooth modules.
Is it possible to use this board without writing custom firmware on the nRF52840 side?
Does the board come with any preloaded UART-to-BLE or AT-command firmware, or is firmware development mandatory?
Please advise the correct approach.
It comes a basic blink sketch by default, but you can use a few methods to interface (Adafruit’s library, Nordic’s SDK, Python, Arduino, etc)…whichever you prefer
Then just make some serial calls and you’re in business!
