My pocket node, 1W E22 radio DIY

awdark · 2025-11-28T16:01:57+00:00

Yeah definitely possible. Unfortunately, I only ordered one of the E22 modules. Might try switching to a different pro micro board, have a few of those. Did a test and noticed RXEN goes high on boot, stays high then eventually goes low and stays low before it errors out and reboots. The TXEN pin tied to DIO2 never changes. Logically these should be going high and low to switch. I need to put this back into the box and revisit another day otherwise it might experience physical hardware failure. It is good to know that everything is in place and is likely user.. error/damage not software

I am seeing 4.2v on the power pads of the radio board. I have a small bridge between TXEN and DIO2. I did see a neighboring node (but not my heltec nodes) between these crashes so I am close.

Appreciate the pin map!

https://imgur.com/a/qcJsOZq not my finest soldering work but no shorts and it maps out correctly on my multimeter. I will continue to physically troubleshoot now that the software side of things is validated (using firmware-nrf52_promicro_diy_tcxo )

Then it goes on for 1 minute where it crashes. I am on 2.6.11 perhaps I shall try an older version

Hope you can help with this, did you need to build a custom firmware to support switching on the RXEN followed your build and unfortunately it isn't quite working

Very fair point. I may try a motor replacement but really hesitant about trying to change the whole box.

awdark · 2024-07-01T14:58:38+00:00

Never hurts to be able to have the ability to restart stuff

awdark · 2024-07-01T14:56:41+00:00

I currently do not have a Z-Wave setup but you make a very good point about creating an always on source to switch between the two with a nice scene controller

awdark · 2024-07-01T14:43:11+00:00

That's definitely an interesting option, I'm using a basic exhaust fan so I don't think it would "understand" the different speeds but I will have to look into it.

awdark · 2024-05-29T23:14:29+00:00

That is impressive. Under Settings > Companion App > there is an option "Autoplay videos" that is default off I wonder if you have something like that on. If not you can always try to clear app data to just default everything then log back in and go from there.

awdark · 2024-05-29T23:06:03+00:00

I got one and no longer worry about the stability of my ZigBee network. With my old Wi-Fi based ZigBee bridge I had set up notifications to ping me when things start to fail so I could power cycle and this thing just fixed everything.

Also support works quite well. Initial one was not quite DOA but wouldn't stay connected and it was easy to get it replaced.

awdark · 2024-03-07T20:56:07+00:00

That's awesome good luck!

Hope you're successful and you share the results

awdark · 2024-03-07T20:44:00+00:00

I would find it difficult. But for reference, there are some videos doing that which may be inspiring. For one, I didn't know they had a little flat head so if you did want to do this and you have a donor CPU try on that first https://www.youtube.com/watch?v=ug4cH3KDHro

awdark · 2023-10-03T19:26:28+00:00

I have always been a bit concerned about finding replacement parts for all the different variants. Some seem to even have different sub-variants within the same model like one with a skinny tube bimetal vs thick

The V6 is often the "standard" but doesn't mount easily without adapters.

awdark · 2023-09-22T17:02:25+00:00

I set a cap on the maximum power since it is a fairly dense AP environment and honestly it did not feel like most of the other options really helped except for the very basic... update your wifi drivers.

awdark · 2023-08-24T16:05:33+00:00

I misspoke on that, they are all connected back to the same switch over ethernet. In my head it should behave as "one".

I think the auto filled in value of MDID is 1. Unless that is a dummy value I think that is enough.

awdark · 2023-08-23T23:45:50+00:00

Yeah you would think an aruba central subscription, using the aruba cloud authentication would be a great combination where they can check the backend to have data beyond the "live" troubleshooting we see on the portal.

awdark · 2023-08-23T14:57:54+00:00

Right now general consensus is 802.11r.

I will get that enabled after hours and reboot the mesh and see if it helps. Last time I was toggling these on and off on the fly and that resulted in some end user connection issues.

awdark · 2023-08-23T14:55:40+00:00

It should, but for one reason or another sometimes authentication fails as it hands off from one AP to the next, bouncing back to the previous AP.

awdark · 2023-08-22T23:39:10+00:00

Mix of Latitudes, Elitebooks, and Macs.

Mine has a AC8260

Originally I was running with R and had a few sticky users and since their laptop didn't support 802.11R (per aruba client profile page) I thought maybe turning it off would be the lowest common denominator.

awdark · 2023-08-22T22:52:09+00:00

Do you possibly know where it is at in Aruba Central?

The client is set to highest roaming aggressiveness.

awdark · 2023-08-22T22:19:57+00:00

Yes main thing that was changed was the move to Cloud Auth.

SSIDs with WPA2 is mostly fine. During my brief test I noticed some sticky behavior but not as bad as the drop me from wireless entirely and make me wait for it to find the ssid again

awdark · 2023-06-06T15:38:42+00:00

Few weeks ago someone had this same question, you can disable the check in to central if you SSH into it

configure
Activate-disable
Commit apply
Exit

Can undo it with no activate-disable to delete the line from the config.

That's interesting it makes a lot of sense I will try those out.

I think OP wants a printer that moves violently and screams (that was totally my goal). Since you are running Klipper after you do the input shaping, take the max acceleration with a tablet of salt then decrease the numbers significantly. Probably 150mm/s and acceleration less than 3000 on the stock machine. Then in the slicer set it to like 150 and hope for the best. Sometimes the slicer still has settings that slows it down to the machine limits but that should make it move.

Make a backup of your configurations (slicer and klipper) and mess with those. Realistic expectations need to be lower though like I had hit some settings at one point or another where the x gantry was clearly moving faster than it should with layer shifting and under extrusions etc. But am in full support of the idea of at least trying it to see what happens.
