How to accomplish lora.nvram_restore() ?

[jalperin]

I'm trying to understand saving & restoring lora nvram.

In boot.py I connect to TTN, send a packet, and do "lora.nvram_save()".
the packet is received.

main.py is:
from network import LoRa
import socket
lora = LoRa(mode=LoRa.LORAWAN)
lora.nvram_restore()
s = socket.socket(socket.AF_LORA, socket.SOCK_RAW)
s.setsockopt(socket.SOL_LORA, socket.SO_DR, 3)
s.setblocking(False)
s.send('LoRa Continues')

The second packet is not received.

I've also tried lora = LoRa(). Also no success.

Any idea what I'm missing?

Update.

comment out lora.nvram_restore() and the second message is received.

Do I need more code or is the restore messing up?

@jalperin you only need to use nvram_save / nvram_restore if you use deep sleep.

Also I'm not quite sure what's your logic for having some of the code in boot.py and some in main.py. Both are executed sequentially.

Yes, thank you. I know I only need save/restore for deepsleep. But was testing it without deepsleep. Shouldn't it still work?

Still looking for any posted example of use of save / restore.

Yes, splitting code irrelevant if deepsleep.
