Problem installing micropython/lora on a STM32F411

[davefes]

Using mpremote mip install lora-sync and mpremote mip install lora-sx127x they appear at /flash/lib/lora on the device.

In simple_rxtx.py I had to add import lib before the line from lora import SX1276X so looks like I didn't understand the install process correctly. Or is there an omission in the example?

I can get this at both units:

Sending...
Receiving...
Timeout!

but no Hello world from MicroPython.

Re. the import pronlem, I've no experience with the stm controllers, but you might want to check that /flash/lib is in the default sys.path. If not, you should add it on startup.

Thanks for the hint:

sys.path
[' ', '.frozen', '/flash', '/flash/lib']

lora is a directory under lib

/flash/lib is in the default sys.path on stm32.

@davefes In the simple_rxtx.py example, the line is from lora import SX1276... you've added an extra X to the end.

Took a minute to work that out, I actually had:

def get_modem():
    import lib
    from lora import SX1276

but appears that when I started this journey I was throwing Xs around.

Thanks for the confirming sys.path.
