Bluetooth passkey keyboard is not appearing on WatchOs(only Pair button) but working fine on iOS.
I have external camera which is working through Bluetooth connection. Camera has pin on itself for pairing process. The thing is when I'm doing pairing on iOS through the CoreBluetooth and requesting protected characteristics it's working fine.
But as soon as I'm trying to do the same on my Apple Watch (Watch-Os) app it doesn't show Pin dialog, it just show Pair/Dismiss button.
Could anyone explain please why it's happening and is there any possible solution to sync Watch and Camera?
Thank you for any help.
I get this error message when i try to upload code to my arduino. Does anyone know what is going on?
I have installed the proper drivers and it works fine. My port appears on the menu and it is the corresponent to the device.

Common error, here is the solution:
1 - Unplug the Arduino
2 - Upload code with no Arduino connected to PC
3 - Reconnect Arduino
4 - Upload code to the Arduino
Good luck!
From terminal:
ls -l /dev/ttyUSB*
# or:
ls -l /dev/ttyACM*
Get the groupname from the result:
crw-rw---- 1 root uucp 188, 0 5 apr 23.01 ttyUSB0
# or:
crw-rw---- 1 root dialout 188, 0 5 apr 23.01 ttyACM0
Add your username to the group:
usermod -a -G uucp username
# or:
usermod -a -G dialout username
Log out and in again for this change to take effect.

If you are on Linux,
just set current user to belong to "dialout" group which is the one who members are allowed to access ports.
Run following:
sudo adduser yourUserName dialout
then relog to take effect

If your using the arduino IDE 2.0 you must close the serial monitor tab if it’s open to upload a sketch. Otherwise you will get this error.
USB may need CH340 driver.
Some Arduinos use the CH340 controller
Find and install the CH34X_Driver_V3.4_Windows.zip
click right on this computer, go to management, device manager, com, find the port of Arduino, then go to tools and in port select the com
I had the COM3 error too and this fixed it.
Open the Arduino application as Administrator
(Shift+Rightclick the app, 'Run as administrator').
I still had to upload without the Arduino connected, then connect and upload.
I had the same problem:
If you are using VS Code with Platform IO and you spam Serial Monitor with many message too fast, then when trying again to upload it will give you the above error. One way to solve it is to press the reset button on your board and immedietly after that to press upload in VS Code. Just don't spam the Serial Monitor too fast, when using VS Code with Platform IO and uploading while monitoring it.
If you are using CLion with Platform IO and you have opened Serial Monitoring via pio device monitor then you must close it and then upload, because it is using the port.
be sure you are not using 2 ides connected to arduino like ARDUINO IDE and VS Code
If you are using the USB-SERIAL CH340 driver: (on some cheaper ARDUINO clones)
Open Device Manager
Open Ports and click on the drop-down arrow to select your port.
Right-click and select "Properties"
Open the "Port Settings" tab.
Click on "advanced" to open a new window:
Un-tick "Use FIFO buffers (requires 16550 compatible UART)" and press "OK"

Please let others know if this worked for you!
I'm trying to learn how to use the Adafruit Flora, and I have followed the guides below:
https://learn.adafruit.com/getting-started-with-flora/windows-setup
https://learn.adafruit.com/getting-started-with-flora/blink-onboard-led
But, I'm struggling withe connecting to a port. It's greyed out in my IDE and I have tried a lot of things like, booting to BIOS and changing the settings to auto, to looking in for any hidden devices in the device manager window. I can't see a "Ports COM" section there and it's preventing me from uploading anything to the flora.
Arduino: 1.6.11 (Windows 10), Board: "Adafruit Flora"
Couldn't find a Board on the selected port. Check that you have the correct
port selected. If it is correct, try pressing the board's reset button
after initiating the upload.
Please help!
First of all check your usb cable. It might be faulty one or it could be charge only. If your board light/blink, it mean power lines are ok. But if there is no action from OS, there might be communication lines broken or missing.
I played for the hole day with my Lilypad USB, and out of the blue it stopped working.
The port in the Arduino IDE is gray (even if i am running as an admin). The device is no more shown the /dev/ or in the device manager for window.
In windows when i plug the device is and push the reset button twice i can see the device under other devices but after a few second the device disappears.
How can i resolve this matter? Is there another hardware factory reset method?
Please help.

I've got a problem that we are hoping there is a simple solution for.
We have a need to allow a push notification to appear on a device when it enters into a certain space. The space is only going to be about 1500 sq ft. So my thought is to set up a wifi network in this area... I'm curious if anyone is aware if it is possible to notify anyone with our app installed on their device when they enter into this wifi space if they want to take a certain action... for instance to open the app?
Create an Android service that is launched when the intent WIFI connected is triggered.
The service will check if the bssid of the wifi connection is the same of the wifi area you want to monitor and then it could either launch the app/show popup/show notification.
