Lora Mesh example is crashing

[ricardolimaui]

What are the steps to reproduce this issue?

1. run the two examples provided in two different windows(creating two folders: 1 for node only with Loramesh and main.py and other for border_router with Loramesh and main_border_router.py)
2. main.py
3. main_border_router.py

What happens?

it successfully start but (the main.py), After a while it gives the following error

42: State detached, single true
Neighbors found: None
opened: 0x3f9512a0
Traceback (most recent call last):
  File "main.py", line 58, in <module>
TypeError: function takes 3 positional arguments but 2 were given

What were you expecting to happen?

waiting forever for the mesh maybe

Any logs, error output, etc?

Any other comments?

I did not change anything in the code, just run the example. I only inserted the Loramesh.py inside of a folder called lib.
I also tried with the main from border router, but it seems like don't gave any error but also don't give any good result in terms of Neighbors

What versions of software are you using?

I am using a brand new lopy4 with a expansion board vrsion3.1 and I also have a pysense

Anyone can help me ? Don't know if it is really a bug

[ricardolimaui]

the line were it gave the error contains this mesh.mesh.rx_cb(receive_pack)

[L-Gibson]

Try using 1.20.0.rc7, fixed the issue for me.

[ricardolimaui]

Hello again
yes L-Gibson 1.20.0.rc7 fixed the problem for sure. Thank you for your help
But know I am facing another problem

in the main node appear
2647: State leader, single true, IP fdde:ad00:beef:0:2592:49a4:52a9:d46a 1 neighbors, IPv6 list: ['fdde:ad00:beef:0:0:ff:fe00:6002'] Ping OK from neighbor fdde:ad00:beef:0:0:ff:fe00:6002 Sent message to fdde:ad00:beef:0:0:ff:fe00:6002
But then in the main_border_router appears an error

Neighbors found: None

Anyone have an idea ?

[L-Gibson]

Seems like main only works on 1.20.0.rc7 and main_border_router works on the latest firmware. Though it seems that main_border_router contains all of the functionality in main (or it can be copied over)

[ricardolimaui]

sorry about taking so much time. Yes indeed with that versions it works but the border router example code does not contemplate the connection to the internet right? For example, a node will be able to connect to the internet throught Loramesh reaching the border router ?
Because seems like with the current code it does not find any border router

Thank you

[ricardolimaui]

Any news about pymesh ? Thank you

[catalinio]

Hi @ricardolimaui,

I've answered on the forum: https://forum.pycom.io/topic/4449/pymesh-updates/20

For the record, the initial problem (error on mesh.rx_cb() function) on release rc8 (I think) I've added another argument, as explained in docs: https://docs.pycom.io/firmwareapi/pycom/network/lora/pymesh/#mesh-rx-cb-handler-argument

Anyway, next week, a new release of Pymesh is planned, with updated micropython scripts which connect to Pybytes (IoT middleware platform) as an example of (multiple) Border Routers to a Pymesh network.

Did I answer your question?

Cheers,
Catalin

[ricardolimaui]

Hi @catalinio upgrading to the 1.20.0.rc12 this error comes again

AttributeError: 'LoRa' object has no attribute 'Mesh'

Where we can find the pymesh version where the message are widespread in the network ?
The available one seems like it don't relay the message but only send the ack.

Which are the methology they use to chose of being a router leader or child?

I am trying to find more documentation, but not easy

Could you provide it ?

Thank you

[catalinio]

Hi @ricardolimaui,

In the version 1.20.0.rc12 the Pymesh module(LoRa.Mesh class) was excluded from build, due to increased binary footprint. We've fixed this issue, but not yet released.
So, we'll release a separate pymesh firmware binary image (next to stable, development and pybytes); these days we're verifying the final image.

Regarding documentation, indeed I need to update it. Meanwhile I've put here some links on openthread core principles: https://docs.pycom.io/tutorials/lora/lora-mesh/; furthermore in the OT cli you have most of the commands available thru pymesh.cli('command') function.

Cheers,
Catalin

[ricardolimaui]

Thank you for quick support @catalinio
Waiting for the new image :D
Just a note In the documentation there is at least a dead link.
"the complete list of commands is here." The link in here "https://github.com/openthread/openthread/blob/c482301ec73b80985445102e4d0a936346172ddb/src/cli/README" is dead(openthread changed the path ?).

Hi!
This seems to still (or again?) be a problem in newer firmware releases, atleast for me.
I'm trying to set up pybytes/pymesh manually in my own main.py instead of having it autostarted, so I've skipped updating my LoPy4 with the mesh specific firmware from pybytes.pycom.io. It seems like network.LoRa.Mesh() does not exist on the 1.20.2.r2 firmware I can find in the Windows Firmware updater.
I want to avoid the firmware from the pymesh OTA update, since it's insisting on using a release candidate version of the firmware (1.20.2.rc11). There does seem to exist an updated firmware on the server though, it's just not the version pybytes is pushing (see https://software.pycom.io/downloads/appimg/firmware_LoPy4_1.20.2.r2-pymesh.bin)

[ricardolimaui]

Any news on this? As I can see there are more open issues similar to this one.

[peter-pycom]

Could you retest with the pymesh firmware that's available via Pybytes? Lora mesh is only supported there
