Bluefruit LE UART Friend

by Randy1 on Sat May 08, 2021 12:31 pm

On the LE UART Friend page there is a video example of Color Picker changing an LED color.
Where can I find the actual Arduino UNO sketch (with actual configuration) used in this video, and wiring diagram for this project?

From other post:
viewtopic.php?f=53&t=179032

I understand that the Mode LED blinks 3x in command mode, and 2x in data mode. My LED is doing that, but it is blinking red, not amber as in the example videos. What does that mean?

On the LE UART Friend page there is a video example of Color Picker changing an LED color.

Are you referring to the embedded Collin's Lab video?

For the LED color, it's probably the same. May have just looked a little different in video vs. real life. It's not an RGB LED, so it can only be one color.

The video I'm referring to is on the "Introducing the Adafruiit Bluefruit LE UART Friend" page and it shows someone using color picker on an iPad controlling the color of an LED using the LE UART Friend and a UNO. Where can I find the actual sketch including actual configuration for that setup, plus a wiring diagram?

As for the mode LED on my LE UART Friend, it blinks the correct amount of times for the corresponding switch setting (CMD/UART). My LED is blinking RED, is that correct? RED usually means an error.

Thanks

The MODE light sounds fine. It just happens to be red in this case.

There are a couple of NeoPixel example sketches here:
https://github.com/adafruit/Adafruit_Bl ... s/neopixel
https://github.com/adafruit/Adafruit_Bl ... xel_picker

I don't think we have a specific wiring diagram other than what is shown in that animated gif (video). But the NeoPixel pin is defined in the sketch and you can change it as needed.

Information about adjusting configuration settings is here:

Thanks for the quick reply.
I ran both sketches and configured for LE UART Friend, but the sketch stops at Factory Reset. Below is the message. What are some of the things I need to recheck?

Please connect using the Bluefruit Connect LE application
Initialising the Bluefruit LE module: OK!
Performing a factory reset:
AT+FACTORYRESET

<- Couldn't factory reset

Please post a photo of your setup showing how everything is connected.

Thanks. Can you post another one that shows the soldering on the header pins closer up.

Thanks. That looks OK.

The example sketch does require some changes. Did you make the changes described here?

I uncommented for UART based boards and get this error.

You also need to comment out the other line. The one with red hilight.
