LoRa Receive Soft Lock

[ProjectInitiative]

Summary

When running this example, there is a soft lock. It can be reproduced by sending another message while the match is waiting, the rx function get stuck, and cannot receive any more messages until the micro controller is reset.

Hardware Summary

• x 2 RP2040 (1 tx, 1 rx)
• x 2 SX1262 Waveshare LoRa Modules (1 tx, 1 rx)

Steps to reproduce

Copy line 89 - 98 and paste after line 98 in the lora_p2p_send.rs file.

Compile and load on the respective pico devices, and after the first message, any messages sent after are lost, and the receive loop does not continue.

Is this a debug statement you added? I am not picking it up in embassy or lora-phy.

DEBUG Loop intera

[ProjectInitiative]

Oh yes, my mistake, I added an additional debug to the example to try and see where the iteration was hanging. I added that between lines 96 and 97 of the recv example.

[ceekdee]

If this is indeed the end of the trace:

TRACE read 3 status 0xd4: 0x[b8, 21, ba] └─ @ :0 INFO rx successful └─ @ :0 DEBUG Loop intera └─ @ :0 DEBUG process_irq loop entered └─ @ :0 TRACE InputFuture::poll return Poll::Pending └─ @ :0

it seems to indicate the polling on the DIO pin (looking for it to go high) is terminating after one poll.

Please provide the revision of Embassy in GitHub which is being used for this test.

Also, if you run normal lora_p2p_send with a delay between runs, does lora_p2p_receive pick up each transmission?

[ProjectInitiative]

This is from my Cargo.lock file: git+https://github.com/embassy-rs/lora-phy?rev=1323eccc1c470d4259f95f4f315d1be830d572a3#1323eccc1c470d4259f95f4f315d1be830d572a3

Going to re run tests on newest release. I see there is version 2?

I ran the examples over night twice, and that is how I discovered the issue, because at some point the receive got stuck.

For the sake of sanity, I cloned a clean repo of the embassy repo. Here is the stack trace:

[ceekdee]

Thank you for re-creating the issue with the current Embassy revision. The trace tells the same story: polling for the DIO1 interrupt pin going high seems to terminate, or there is an error in handling that event, or the logging itself fails.

I'll attempt to recreate it in my testbed and debug it further. I may need to request assistance from the Embassy team.

There is a lora-phy version 2, but there should be no difference in how it handles a read continuous operation. Embassy will be updated to use version 2 once another Embassy dependency is updated.

[ceekdee]

In your local Embassy clone, can you make a code change and re-test?

https://github.com/embassy-rs/embassy/blob/2c38dd17b9a5a507fc77d90d78486e4764234752/embassy-lora/src/iv.rs#L286

Take out the check for the LoRa board (BoardType::RpPicoWaveshareSx1262) so that only the following is executed:

self.dio1.wait_for_high().await.maperr(|| DIO1)?;

That is, always wait for high.

This comes from a suggestion posted in the Embassy chat as a result of the question I raised there.

[ProjectInitiative]

That appears to work. going to run another overnight test!

[ceekdee]

If the overnight test verifies the fix, I will make a PR for the embassy-lora crate.

[ProjectInitiative]

Probably don't need an overnight test. I had it running all day, haven't seen a single error or hang. Will continue if desired.

[ceekdee]

Seems to be a sufficient test. Thank you! I'll work on a PR for embassy-lora and note that here when it is opened.

[ceekdee]

Issue closed with PR applied to Embassy.
