Could not connect to server

[DragosLeuBre]

Hello all,

Recently, I tried connecting to my XC112+XR112 devices (mounted on a Raspberry Pi 4), through the exploration server. A quick note, in the past I was able to connect without any issues, but with this SW version I have the following issue: once I try to connect to the specified IP address, it pops up the "Could not connect to server" message.

From Putty I get the following messages:

01:22:35.752 (I) (exploration_server_base) Got command: get_version 01:22:35.752 (E) (exploration_server_base) Unknown command get_version. 01:22:35.752 (E) (exploration_server_base) Sending error "Unknown command" to client 01:22:35.760 (I) (exploration_server_base) Got command: get_system_info

While from the GUI I get:

Traceback (most recent call last): File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\app\old\app.py", line 1610, in connect_to_server self.client.start_session(config) File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\client.py", line 111, in start_session return self.subclient.start_session(config, check_config) File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\base.py", line 114, in start_session ret = self.setup_session(config, check_config=check_config) File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\base.py", line 89, in setup_session session_info = self._setup_session(config) File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\json\client.py", line 543, in _setup_session info = self._init_session() File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\json\client.py", line 569, in _init_session return self._protocol.init_session() File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\json\client.py", line 388, in init_session self._send_cmd(self._session_cmd) File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\json\client.py", line 36, in _send_cmd s = json.dumps(cmd_dict, separators=(",", ":")) File "json__init__.py", line 234, in dumps File "json\encoder.py", line 199, in encode File "json\encoder.py", line 257, in iterencode File "json\encoder.py", line 179, in default TypeError: Object of type Profile is not JSON serializable

Has anyone any idea on how to fix this?

Thank you!

Hello @DragosLeuBre

Could you confirm which version of the exptool is running? It should say which version in the bottom right of the GUI.

Best regards, Anton

[DragosLeuBre]

Hello @vackraetraed

The version is Lib 5.2.4

Kind regards, Dragos

[vackraetraed]

Also, which firmware version of the exploration server is running on the Raspberry PI?

Best regards, Anton

[DragosLeuBre]

It's acconeer_rpi_xc112_a111-v2_13_0, which should be the latest one (as I downloaded it this morning from the site). With the previous (v2_12) I had no issues (also, with a previous version of the exptool, which I don't remember the versione unfortunately).

Generally, I should be using the latest versions of the software/firmware.

Kind regards, Dragos

[vackraetraed]

I'd try to purge the configs before running: python -m acconeer.exptool.app --purge-config

Though I have never tried running Windows or the portable tool myself. Perhaps the command needs to be inserted at some specific part of the start up.

Best regards, Anton

You can also try to print the cmd_dict in File "C:\Users\conAlt41\Desktop\Python\portable_exploration_tool\tools\python-3.9.10-embed-amd64\Lib\site-packages\acconeer\exptool\a111_clients\json\client.py", line 36, in send_cmd s = json.dumps(cmd_dict, separators=(",", ":"))

And post its result here.

Best regards, Anton

[DragosLeuBre]

Thank you for the suggestions, I tried both without any results.

This is what gets printed:

{'cmd': 'get_version', 'api_version': 3} 15:53:13.780 | INFO | MainProcess | acconeer.exptool.a111._clients.json.client | No get_version cmd, try get_system_info {'cmd': 'get_system_info', 'api_version': 3} 15:53:13.789 | INFO | MainProcess | acconeer.exptool.a111._clients.base | reported version: 2.13.0

Kind regards, Dragos

[vackraetraed]

Strange, is the cmd_dict empty? You did not try to print it after the failing command?

This is what it looks like for me: {'cmd': 'get_version', 'api_version': 3} 16:17:45.079 | INFO | MainProcess | acconeer.exptool.a111._clients.json.client | No get_version cmd, try get_system_info {'cmd': 'get_system_info', 'api_version': 3} 16:17:45.085 | INFO | MainProcess | acconeer.exptool.a111._clients.base | reported version: 2.13.0 {'cmd': 'setup', 'repetition_mode': 'on_demand', 'groups': [[{'sensor_id': 1, 'service': 'sparse', 'config': {'range_start': 0.18, 'range_length': 0.6000000000000001, 'gain': 0.5, 'hw_accelerated_average_samples': 10, 'profile': 2, 'downsampling_factor': 1, 'maximize_signal_attenuation': 0, 'sampling_mode': 1, 'sweeps_per_frame': 16, 'tx_disable': 0, 'power_save_mode': 'active', 'asynchronous_measurement': 1, 'mur': 6}}]], 'api_version': 3}

Hi @DragosLeuBre

I managed to reproduce the issue on Windows 11, are you using Windows 11?

[DragosLeuBre]

Hello @vackraetraed

Actually I still use Windows 10. The message printed is the one I attached yesterday (after the fail), so basically no information is provided by the sensor.

I also tried using a previous version of the client, but I still have some compatibility issues, as it gives me another fail due to the fact that the sensor firmware is newer.

Kind regards, Dragos

[vackraetraed]

Hello @DragosLeuBre

Sounds strange, I am getting the exact looking error as you had before but my command that is being sent is for sure looking quite strange here. I will continue looking into it, maybe it is related. Specifically the profile field looks like this: 'profile': <Profile.PROFILE_2: ('2', 2, 0.12)> It should look like 'profile': 2 So in this case it is quite logical that it would produce the error which both you and me see.

What error are you facing when using previous versions?

[DragosLeuBre]

Thank you @vackraetraed

It's not an error per se, it's just an incompatibility between the sensor firmware and the exptool client versions, as they don't match, and as soon as I run the client I receive a fail saying that I need to update the client.

[vackraetraed]

Hello again @DragosLeuBre

It looks like Windows does not recognize enum as enum. Temp fix is to go into acconeer/exptool/a111/_clients/json/client.py add "from acconeer.exptool.a111._configs import ConfigEnum" in the beginning of the file.

Then in the JsonProtocolExplorationServer class in the same file. In function setup_session, there is a check: elif isinstance(config_val, enum.Enum): Change this to: elif isinstance(config_val, ConfigEnum):

I could at least start the Exploration tool with envelope using this. We will work on updating the exploration tool fully with this.

[DragosLeuBre]

Hello @vackraetraed I can confirm that now it works with the tweaks mentioned.

Thank you!

[vackraetraed]

Hello @DragosLeuBre

Excellent! From further analysis it seems this problem came from installing shiboken6==6.3.2 (released last monday) shiboken6 somehow now imports its own definition of enum which does not equal the standard python enum. Revering shiboken6 to shiboken6==6.3.1 should also fix the issue without altering the code.
