Hello everyone,
I am fairly new to using PlatformIO to do embedded work, so I apologize if this is an obvious question, I just can’t figure it out on my own.
For context, I am using a Heltec AB01 board at work for LoraWan stuff, and we want to deploy a bunch of them to collect data. The only drawback with our method is that with each new board, I have to go into the code, type in the new devEUI, appEUI, and appKey, then recompile the program. This is fairly tedious, especially when we plan to scale up to a lot of devices. I am attempting to write a program to automate this using “pio run” and reading from a CSV of IDs, but one issue has me stuck.
My main question is if there is a way to have arguments which are passed into variables each compile that can be easily modified?
For example, in a standard C program, you might have an int main (int argc, char * argv[])
and then when you run the code you can tack on a file name or switch in the command line, but I am lost as to if there is an equivalent version for PIO development.
Right now, my best idea is to have the IDs read, then I have a separate identity.h
in which I was going to overwrite the values, but it seems clunky to try and write to a .h file like that.
If anyone has any better solutions than mine, I’d really appreciate it!
Thank you,
Dirk
