Burn

Firmware

1.The module is embedded with ARM MCU. For program downloading, please use the J-LINK downloader.
Any other serial port or JTAG

ISP

ICP are unavailable to download.

1.The burn firmware needs to be completed in two parts. Since the protocol stack provided by NORDIC is not
loaded in the program, in the second development, you need to use the official burning tool nRFgo studio to
burn the protocol stack, and then use nRFgo studio to burn. The hex of the application code; you can also use
the official burning tool nRFgo studio to burn the protocol stack, and then download it with IAR or KEIL.
