LMIC-node project adding MCCI LoRaWAN LMIC library@^4.0.0

[mitjad123]

Hi,

I am setting LMIC-node project on my win10 platformIO project targeting heltec wireless stick lite
I tried to add mcci-catena/MCCI LoRaWAN LMIC library@^4.0.0 library and got this error:

PIO Core Call Error: "Error: Invalid 'D:\userX\Documents\PlatformIO\Projects\HelctecWiFiLORAone4all\platformio.ini' (project configuration file): 'No section: 'common''"

My platforio.ini:
; PlatformIO Project Configuration File
;
; Build options: build flags, source filter
; Upload options: custom upload port, speed and extra flags
; Library options: dependencies, extra library storages
; Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:heltec_wireless_stick_lite]

Aha, it looks like I would have to add MCCI lib before and changed platforio.ini

lib_deps =
mcci-catena/MCCI LoRaWAN LMIC library@^4.0.0

Apparently you have edited the platformio.ini file included with LMIC-node and have removed essential parts e.g. the [common] and other sections. There is no need to remove anything from platformio.ini. Use the original platformio.ini and the problem should be solved.

Before making any changes first read the included documentation.

If you wan't to slim down platformio.ini for just your board, be careful with what you change or remove and only do this if you understand the consequences.

Hi, sorry for being negligent.
You were right. After using the original ini file, it almost worked.
I only had to change:
-D BSFILE="boards/bsf_heltec_wireless_stick_lite.h"
To:
-D BSFILE="../boards/bsf_heltec_wireless_stick_lite.h"

Because otherwise I had an error:
In file included from src\LMIC-node.cpp:53:0:
src\LMIC-node.h:79:46: fatal error: boards/bsf_heltec_wireless_stick_lite.h: No such file or directory
compilation terminated.
*** [.pio\build\heltec_wireless_stick_lite\src\LMIC-node.cpp.o] Error 1

Thanks
Best regards

Thanks for your feedback.

Regarding:

I only had to change:
-D BSFILE="boards/bsf_heltec_wireless_stick_lite.h"
To:
-D BSFILE="../boards/bsf_heltec_wireless_stick_lite.h"

That is strange because boards is a subfolder of src, they are not siblings (which the ../ implies).
Maybe you changed something to the folder structure?

[mitjad123]

Yes, I did (as well as some other stupid things). But it is OK now.
Thanks
