I´m new to RAK5010, and before bying, trying to understand the stricly necesary to use, debug and program with custom code the module.
In the quick start guide, is not clear if the module brings with a bootloader ready.
Also, wich are the options (eg programming languages) than can be used. I suppose the SDK of Nordic is an option, also Micropython (in that case I need a Jlink hardware?), Arduino?
Can the module be flashed using USB/BLE or UART / USB converter?
