intermittent bluetooth connection
Hi I've been having a strange connection problems with my Corne keyboard, I've had this keyboard for the pass 6 ish months and this issue has only presented recently (2 weeks)
It connects and disconnects multiple times in like a minute, and can happen this multiple times during the day, which is frustrating considering that it messes up my work + sometimes when it disconnects it get stuck in my last registered input and thissssssssssss can happen

Sorry to hear that you're experiencing intermittent Bluetooth connection issues with your Corne keyboard. This can be frustrating, especially when it affects your work.
Let's try to troubleshoot the issue. Here are a few things to check:
1. Enable increased transmit power: In your ZMK
.conf file, add the following line to increase the transmission power of your keyboard: CONFIG_BT_CTLR_TX_PWR_PLUS_8=y. This might improve the range and stability of your Bluetooth connection.
2. Disable 2M PHY: 2M PHY is a higher speed BLE connection that reduces power usage but also reduces range. Try disabling it to see if it improves your connection stability. In your ZMK .conf file, add the following line: CONFIG_BT_CTLR_PHY_2M=n.
3. Check for interference: Other devices in your environment might be causing interference with your keyboard's Bluetooth signal. Try moving your keyboard and device away from other Bluetooth devices or sources of interference.
4. Reset your keyboard: Sometimes, a simple reset can resolve connectivity issues. Try resetting your keyboard by pressing the reset button or shorting the reset pins to ground.
5. Check your battery level: Low battery levels can cause connectivity issues. Make sure your battery is charged, and try replacing the batteries if they're old or worn out.
6. Check for firmware updates: Ensure that your keyboard's firmware is up to date. You can check the ZMK documentation for updates and follow the instructions to update your firmware.
If none of these steps resolve the issue, it's possible that there's a hardware problem with your keyboard. You can try reaching out to Typeractive support for further assistance or guidance.
Remember to check the troubleshooting documentation for more information on resolving Bluetooth connection issues.how do I know I'm on the latest ZMK version ?
When was the last time you updated ZMK?
I mean forking your github to make my keymaps count well just once like months ago, if that doesn't count it means I don't know how to update it
You can push an empty change or rerun the action!
ohh ok
@Nick updated myyyyyyyyy keymaps and its still happening as you can seeeeeeeeeeeeeeee
constantly disconnecting and getting stuck in the last key input, yesterday didn't happen, not a single time
BTW this is happening in both my computers (mac and pc) so I believeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee is a hardware issue
I got the solderless version will unplug and plug back the sbc and see if it fixes anything
nope it didn't fuck.
@TheBigChile did you recently introduce something that has a lot of interference?
did you try increasing transmit power?
nope not a single new thing
and yes
I only have a mouse with a usb reciber so no bluethoot and the keyboard thats it, my earphones are wired
This doesn't seem like a hardware issue is all I can say for sure
You may benefit from trying ZMK's experimental new bluetooth stack
how can I get that?
Bluetooth Configuration | ZMK Firmware
See the bluetooth feature page for more details on the general Bluetooth functionality in ZMK.
cool thanks I'll keep trying
It looks like the only one that make sense to try is the first one
yes that's the one I'm referencing
battery is low atm so I will charge them and also I saw this, will try after a full charge
I did add two more connections to my keyboard recently
ah could be related to that
I think there's an option that disables all the other profiles
It keep happening, I erase all profiles and limit my profiles to only one computer and I added the bluuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuetoth beta setting
This is getting anoying af
will try CONFIG_BT_MAX_CONN and CONFIG_BT_MAX_PAIRED = 1
updated Bluetooth drivers on windows
Did not work any of this ^^
hmmm... so experimental didn't work, one connection didn't work
:think:
@Nick after a bunch of attempts and frustrations not only with the keyboard but also with Windows well being F Windows. I decided to transition to Linux and after that I have no issues with the keyboard
My guess, at least the last 2 updates made my either Bluetooth hardware unstable or the drivers or it has something to do with how W11 manages power as I notice that some stuff in my PC just started to fail after waking up from Sleep state
mind you this is a 6 months old computer with fancy specs
so strange
i’m surprised the new experimental connection setting didn’t work
