Bluefruit LE SPI Friend - Cant Factory Reset

[Youssef_Ismail]

Hello,

I am working with an Arduino Micro and Bluefruit LE SPI Friend. We wired it up according to the tutorial on the Adafruit website (https://learn.adafruit.com/introducing- ... out/wiring)

When I try to perform the factory reset as directed on the website, I get an error message that it "Couldn't Factory reset"

I have it wired up as hardware SPI and I are using the factoryreset sketch verbatim. I made no changes to the sketch.

The module initialized fine, the red light blinks, I can even connect it to the phone using the bluefruit app and the blue light on the module goes on.

Not sure what is going on, can you help?

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

Here are some photos of the wiring.

We tried the hardware factory reset, the software factory reset and the ATCOMMAND factory reset, neither worked.

This is the message we received when we tried a software factory reset

Adafruit Bluefruit AT Command Example
-------------------------------------
Initialising the Bluefruit LE module: OK!
Performing a factory reset:
AT+FACTORYRESET

<- Couldn't factory reset


We also updated the firmware through the Bluefruit LE Connect App. It connects fine with the app and we were able to download and install version 0.6.7 and it still did not work.

Any help you can provide is greatly appreciated.

Try doing a hardware reset: hold the DFU pin low for more than five seconds, then release it.

I am having the exact same issue. Did anyone find a work around? Or is replacement the way to go?

[adafruit_support_mike]

Have you tried the hardware reset mentioned above?

[Timonea]

I did but it turns out my solder was faulty. Thanks anyways :D

Glad to hear it's working for you.

I was having this error too with a new Adafruit Bluefruit LE UART Friend and Arduino Uno setup.

When you follow the tutorial to wire the Arduino, it is wired for software serial UART. But the example sketches, out of the box, are configured initially for hardware SPI. So the object in the sketches needs to be changed to be the Software Serial UART.

I'm a noob so maybe this was easy for everyone else but it took me a bit to find in the manual.

Hope this helps someone else save some time.

rabbic, how did you change the code to work with soft serial? I too am a noob and am not sure where to find the steps.

Make sure your soldering is perfect - side view shows you if there's any gap. Once I fixed the solder, it immediately worked.

Hello.

I am attempting to complete the Bluefruit LE Heart Rate Monitor Tutorial (https://learn.adafruit.com/introducing- ... atemonitor) with an Adafruit Flora.

I have had the same problem with 'can't factory reset'. I am not sure if mine is wired properly.

How should it be wired?

Thank you!

I've found with the latest library (Teensyduino 1.36 beta #4) and presumably all older versions, the error "Can't Factory Reset" occurs with high CPU speeds (168 MHz and higher). The LE SPI seems unstable at 96 MHz, but no errors. I've only gotten stable operation at 72 Mhz (using a Teensy 3.6).
