Hi @all,

We’ve updated the RAK online compiler and RUI SDK today so that it can be used more and more easily and robust.
Now, you can download the latest “Application” source code from Github:

and compile them with RUI SDK on RAK online compiler according to our new document:

The latest RUI APIs have been updated here:

More information about RUI i will share in this topic continuously:

Please focus on it.

BTW, you can only use RAK online compiler through SSH now, and i know it is not easy. I’m sorry for that, but we’re building a beta web version compiler so that you can compile your own customized firmware on broswer.

In a word, RAK will do our best to supply better and better products and services for users/developers.
RAK sincerely hope that “RUI software platform” + “RAK IoT modules” can help you to create more and more amazing IoT products easily!
That’s what RAK want to do!

Hi Fomi,
Received. Thank you very much!

Hi Fomi,

I have a RAK7205, which I think is basically the same at the RAK5205
I have used the online compiler to compile the standard example code from Git for the 5205.
When I try to upload the firmware, the STM32Vube programmer says that the program is too large.
Below is the log.

09:57:15 : File : stm_xx.bin
09:57:15 : Size : 131104 Bytes
09:57:15 : Address : 0x08000000
09:57:15 : Erasing memory corresponding to segment 0:
09:57:15 : Error: Operation exceeds memory limits
09:57:15 : Error: failed to erase memory

I have not changed any of the code. Any ideas?
