Error reading char at handle 26, status=5 #42

Looking at the documentation for BLE error codes:
Seems to be some sort of authentication failure. Any idea why? I pressed the pairing button, maybe I could also try completely resetting the desk |
|
hey did you get a fix for this? |
|
I didn't! If you have any additional information though, please let me know! |
|
I was thinking maybe the desk is asking for a code but esphome does not support codes yet |
|
mmmh, that could be a reason but I wouldn't think so, this is working for so many other people |
|
esp 32 and my table is a new idasen |
|
Okay, I bought mine in september 2020 🤔 |
|
Got the same errors in the log unfortunately. Was working with 1.2.3 until a few days ago but now neither 3.0.0. nur 1.2.3 is working. |
|
hmm so its nothing new then, where did u get your esp 32 i got mine off amazon it may be the ble chip (which i doubt) |
|
@j5lien can you please look into this? |
|
Happens to me, too. Workaround:
Sensors are not updating, though... |
|
I have the same issue :(
I don't think this is the case, since when pairing the desk to my phone it didn't ask for any pairing code |
In my case workaround doesn't help. Actually, it helps for a moment, and then I get the same error. |
In the end, I tried this yesterday, and it worked! I've used v1.2.2, because v1.2.3 did not work for me. Saw this workaround originally here and followed its steps. It is working since yesterday, both moving the desk and reading the sensors To do the initial pairing with the desk used the following config: esphome:

Thanks for sharing. I'll try this approach. |
|
Reading sensors works, for now, however moving is not :( |
|
And it got disconnected after 2 days and doesn't connect anymore... 🤞 for @ammmze PR mentioned above |
|
@leukanos at least you progressed 3 handles! 😁 I think I'll try the pull request out with my installation (guide) |
|
I did pretty much what andrethrill said in the comment below me. Things work, but the sensors don't :/ I'm using Adafruit ESP32 feather board if that's any help. The controls don't work for down (up and stop do), but the automation does (because it's behaving like a curtain). |
👍🏻 Let us know how it goes. Hopefully it gets things rolling. While I got mine paired and from the logs it looks pretty good, I did notice some quirks in home assistant. Often I would be manually raising and lowering the desk and the speed and other statuses would get stuck showing it in motion (i.e. having a positive speed value greater than 0), however in the esphome logs I did see 0 as the last speed. So I wonder if esphome is throttling the messages to esphome and dropping some of them. Regardless, I think it's a separate issue that we can dig into more once we are successful in the pairing process. Edit: Ah...yea...looks like the reason why home assistant doesn't always see the final state is because there's not enough buffer space to store all the messages that get produced when moving the desk up/down. |
|
I’m also seeing this issue. I just got a new desk, partly because I wanted to automate it with this project 😄 Is there anything I can do to test/debug? It isn’t clear from reading the thread if there are any leads to follow up on. Otherwise I’ll do my own investigation |
|
Unfortunately we have not found a fix yet. But please send your progress here so others don’t have the same issue |

small update from me:

well thanks to you this is the first time HA moved my desk |

@ammmze Neat! I also tried this config out and it seems to partially work. I can now move the desk up and down with Home Assistant. However, the sensors don't seem to be updating. I don't need them for now, it isn't quite as nice but I can work with a cover percentage in Home Assistant so I just removed them for now. My more minimal config therefore look like... external_components:

@d0ugal the first time I loaded it in the sensors did not update but then I unplugged it and plugged it back in (the esp) and it’s working |
|
Good point, the height did seem to update once after restart. It didn't seem to update after that but I'll do some experimentation. |
|
@d0ugal Did you ever get a chance to do some experimenting? I'm getting the same thing where the sensors are updated when the ESP first boots up but never again. Update: Slightly frustratingly the sensors seem to have started updating for me now and I'm not really sure why. The main thing I did before they started working was pair the desk to my computer using Bluetility (it's a mac app but I'm sure sure there are similar ones for other platforms) and subscribed to height changes there. Then I turned off bluetooth for my computer and my phone which I've previously connected to the desk and restarted the ESP holding down the pairing button on the physical desk control. I've restarted the ESP and unplugged and replugged in my desk many times at that point so I'm assuming it was something to do with the pairing and unpairing that did it rather than just the restarting but honestly I don't really have any idea what happened 🤷♀️ |

@callumgare I had some problems until 4.0.0 was released. Since then it has worked fine and I don't get the issue anymore. My full config is now the following; external_components:

Thanks for that @d0ugal! |
Hi, I'm having a weird problem, preventing me to use this at all. As far as I know, @sud33p has the same issue.
I wanted to set up an ESP32 with for my Idasen desk with this config:
However, I keep getting the same error:
This error is repeating over and over again, until I press the pairing button on my desk. Then this happens:
Looks promising at first, but then the error pops up, it disconnects again and the loop with the first log I showed continues.
Any idea what could be causing this?
If you need any more information, please let me know!
Thank you.
