Hi, I have been having trouble uploading Arduino code to my RAK4630-based board. The COM port on Windows keeps switching as described here, and I am planning to update the firmware. I keep seeing references to the 4631, and I installed the 4631 board manager, as there were no direct references to 4630.
Can I treat a 4630 as if it were a 4631, or is there anything I need to be aware of? Essentially, are the firmware+bootloader for 4631 backwards-compatible with 4630 hardware?
Also, what method do you recommend for updating the firmware? From my research, it seems to be the same options as described here, it’s just confusing because the guide is for 4630, but references 4631 most other times.
This guide describes how to download the bootloader of RAK4630 in case of any crash or erase during use.
… and then each hardware list requires the 4631. Here’s an example of the hardware required for USB firmware update:
Hardware and Tools Required
- WisBlock Base RAK5005-O
- WisBlock Core RAK4631
- The latest bootloader (V0.4.2 - WisCore_RAK4631_Board_Bootloader.zip)
- Adafruit-nrfutil application depending on your OS version
- USB cable
The most likely answer is that I can just do everything the same – however, I just want to make sure that I am not locked out of anything before I get to grinding away at firmware updates. If need be, I will buy the 4631, especially if the 4630 is deprecated.
Here’s a copy of my INFO_UF2.txt file – it seems to match the “How to Check If You Have the Updated RAK4631 Bootloader” section of the docs (sorry, can’t post more than 2 links as a new user).
