I would like to use my RN-42 Bluetooth module to create a wireless serial communication interface between my Windows 10 laptop and Arduino Mega 2560 R3 for programming in IDE. After installing a serial port terminal application, configuring my module, and pairing it with my Windows 10 laptop, I uploaded a simple sketch by USB connection to confirm communication by Bluetooth. However, I understand it is more difficult to upload a sketch by Bluetooth. This may involve changing module settings in command mode and modifying baud rate to reprogram the bootloader. Would anyone happen to have advice to accomplish this? Thank you.
