python-broadlink: StorageError: The device storage is full while learning and workaround

You can use python3 broadlink_cli --device "0x61a2 192.168.1.6 24dfa7b9c689" --rfscanlearn.

YAYAYAYAYAY!!! This command did the trick!!! 😃)))) Now I need to learn the RF codes and configure the OpenHAB binding 😃)) I’m so glad I’m able to continue to the next step. Thank you so much for your help @felipediel @KTibow 🙏🙏🙏

You can use python3 broadlink_cli --device "0x61a2 192.168.1.6 24dfa7b9c689" --rfscanlearn.

Thanks for the pointer. You are right. Changing from using the “rm” class to using the “rm4” class works! Glad to finally get this working!

You’re right! My mistake, I’m sorry!

I was able to detect the problem using the library directly on python console, but the treatment is indeed in the other project.

*By problem I meant ask to check_data() before pressing the button.

Sorry I reopened this thread. The problem still happens, but I think I can help to replicate. And I believe it is a code problem.

Hope this help to solve. I spent my afternoon trying to make it work and getting this error. I notice when we started to learn any code, and don’t press any button on remote, the error popups in screen (about 5 seconds after the command) while the RM4 Mini still with the white led on.

But, if you press the remote control button just after entered the learning mode, it works beautifully.

So to replicate the problem, just enter the learn mode and just wait 5 seconds.

I’m a developer but zero skills with python. So, I suppose, the problemas has something about the delay between entering the learning mode and “grab” the code from the device while it still not ready yet.

And the error about full storage is just a “bad catch” somewhere, or the “bad code” returned crashes the write method.

Hope it drives for the solution, and btw REALLY THANKS for all the effort spent.

I think the IP address is wrong.

Wonderful! You were right!!! I didn’t notice I made a small mistake in the IP address. Sorry for this foolish mistake.

My next step was to record my appliances wireless remotes’ codes. However, the RM4 Pro didn’t recognize any RF codes, and, as such, it returned a “No data received…” message.

pi@raspberrypi:~/python-broadlink/cli $ python3 broadlink_cli --device "0x61a2 192.168.1.6 24dfa7b9c689" --learn

No data received...

On the other hand, when I tried to record IR codes the RM4 Pro properly recorded them:

pi@raspberrypi:~/python-broadlink/cli $ python3 broadlink_cli --device "0x61a2 192.168.1.6 24dfa7b9c689" --learn

Am I missing a necessary step before recording RF codes?

@mjeshurun they mean to run it from the command line, possibly with python3 -m before it.

The try: except clause is similar to an if statement, but we ask for forgiveness instead of asking for permission in order to improve performance.

If statement (asking for permission)

if code_received:
    device.check_data()
else:
    print("No code received")

Try except (asking for forgiveness)

try:
    device.check_data()
except ReadError:
    print("No code received")

This code snippet is exactly what you are looking for.

Thank you 🙏 To double check I understand what you mean. My next step is to open the broadlink_cli file with a text editor and check if the commands you wrote (and those highlighted in the code snippet) are in the broadlink_cli file verbatim?

Or do I need to add the commands you wrote somewhere into the broadlink_cli file?

When you call devices[0].check_data(), you need to catch the exceptions with a try: except clause. Check the CLI implementation for more details.

What command are you using to learn the code?

I’m following this set of commands:

python3

>>> import broadlink

>>> devices = broadlink.discover(timeout=5)

>>> print(devices)

>>> devices[0].auth()

>>> devices[0].enter_learning()

After the last “enter_learning” command I get the error message, so I cant continue to the next commands that are supposed to be:

>>> packet = devices[0].check_data()

>>> print(packet.hex())

>>> devices[0].send_data(packet)

One more note just to complete my view of things. My “old” RM3 mini still requires the old “rm” class (old firmware being “v57”). The new RM3 minis I have purchased recently do not work with the “rm” class, they require the use of the “rm4” class (new firmware being “v44057”). Thanks for the help sorting this out.

But I can work with the most basic commands. Try the following lines in the Python interactive shell:

Can you confirm whether to try these commands in the Python console after commenting out line 74 in exceptions.py, or doesn’t it require commenting out that line at all?

Here I mean after commenting out line 74.

But actually, in my test, the first portion works even without commenting out the line. The check_data method in the second part is giving out StorageError.
