LLCC68 LoRaWAN failed with -1106 and -9

lioff commented 9 months ago

Describe the bug I am using the LoRaWAN example with an LLCC68 on EU868. However, beginOTAA fails during checkADB. It seems to be related to the limited supported SF of LLCC68.

To Reproduce

/*
  RadioLib LoRaWAN End Device Example

  This example joins a LoRaWAN network and will send
  uplink packets. Before you start, you will have to
  register your device at https://www.thethingsnetwork.org/
  After your device is registered, you can run this example.
  The device will join the network and start uploading data.

  NOTE: LoRaWAN v1.1 requires storing parameters persistently!
        RadioLib does this by using EEPROM (persistent storage), 
        by default starting at address 0 and using 448 bytes.
        If you already use EEPROM in your application,
        you will have to either avoid this range, or change it
        by setting a different start address by changing the value of
        RADIOLIB_HAL_PERSISTENT_STORAGE_BASE macro, either
        during build or in src/BuildOpt.h.

  For default module settings, see the wiki page
  https://github.com/jgromes/RadioLib/wiki/Default-configuration

jgromes commented 9 months ago

This has been discussed (at length) here: https://github.com/jgromes/RadioLib/discussions/946

It's been fixed in upstream, just not released yet. Are you using the last release? And if so, can you try with the current master?

lioff commented 9 months ago

@jgromes: I used the latest release (6.4.2). Now I pulled the current master and get the same error:

Based on the discussion you mentioned I tried again with joinDr of 3:

state = node.beginOTAA(joinEUI, devEUI, nwkKey, appKey, 3);

Now it seems to attempt a join request with SF 9, reaches a timeout, and then fails in a second attempt with SF 12. I am not sure if this is expected behavior (as the SF 9 request timed out).

Any idea what the problem could be?

lioff commented 9 months ago

I see now that TTN actually receives (at least some) of the join requests. The first one appeared ok (even though I did not notice any change in the RadioLib debug output). Since then, however, I get the error "DevNonce is too small" in TTN console. I tried to reset DevNonce in TTN, but no change.

jgromes commented 9 months ago

It looks like the original problem was resolved (TTN now obviously receives your join requests), so I will convert this to a discussion.

Based on the discussion you mentioned I tried again with joinDr of 3:

Setting appropriate DR is required, since LLCC68 only supports a subset of spreading factors.

I see now that TTN actually receives (at least some) of the join requests. The first one appeared ok (even though I did not notice any change in the RadioLib debug output).

So ... can you post the output? Was there a timeout, or did you receive the join accept message? Either way it might be worth it to wipe the persistent memory, and (temporarily) allow reusing dev nonces in TTN.
