Bluefruit Le Uart Friend and Arduino

[ktownsend]

The modules don't ship with the latest firmware installed. You need to update to the latest version using the Bluefruit LE Connect app. Let me know if the DFU Factory Reset works as well? Thanks.

[dina91]

I checked it and it is updated to the recent update. Still didn't work. It couldn't do a factory reset or at command.
This is the error I got from atcommand.

C:\Program Files (x86)\Arduino\libraries\AdafruitBluefruitLEnRF51master\Adafruit_BLE.cpp: In member function 'int Adafruit_BLE::readBLEUart(uint8_t*, int)':
C:\Program Files (x86)\Arduino\libraries\AdafruitBluefruitLEnRF51master\Adafruit_BLE.cpp:543: error: invalid conversion from 'uint8_t*' to 'char*'
C:\Program Files (x86)\Arduino\libraries\AdafruitBluefruitLEnRF51master\Adafruit_BLE.cpp:543: error: initializing argument 1 of 'size_t Stream::readBytes(char*, size_t)'

I have a project demo this week and I want to get this working. It looks like this Bluetooth is not working. Can you send me another one asap?

[ktownsend]

Can you please post the results of the ATI command? It's hard to help without providing the information we need to understand what's happening. Thanks!

Those errors have nothing to do with the HW, BTW, they appear to be a SW config issue and some sort of conflict with the setup on your Arduino IDE or board selection.

Have you tried updating the library to the latest version? https://learn.adafruit.com/introducing- ... d/software

It can't be a HW issue since it's failing at the compilation stage, which is completely independent of anything with the HW, but again, seeing the actual ATI command response will help understand what is happening here.

Sorry to keep insisting on this, but it's important or we don't have the information we need to help you here.

What version of the Arduino IDE are you using as well? Make sure you are running a recent version.

[dina91]

I have the libraries and Arduino IDE to the most updated version.
How do I perform the ATI command? I don't find a sketch example. All I find is this link but I don't know how to preform this.

Please let me know asap. I have a project demo on Tuesday and I want to get this working. I am trying to use the bluefruit app uart so I can transfer the data by using data mode and command mode and I am still facing the same problem.

[ktownsend]

You can connect something like an FTDI cable to the UART pins on the board, open a terminal emulator at 9600 baud with HW flow control enabled (CTS + RTS), and then just type the 'ATI' command.

Alternatively, you can simply power the UART board up, and it should start blinking with the red light meaning that it is advertising. You can then use our Bluefruit LE Connect app for either iOS or Android, and then connect to your device and go to the 'Information' part of the app where every service and characteristic on the device is listed. If you post a screenshot of the contents of the Device Information Service values, that is the same information as the ATI command.

Information on wiring up an FTDI cable is available in the learning guide here: https://learn.adafruit.com/introducing- ... ftdi-cable

Links to the Bluefruit LE Connect apps are available here: https://learn.adafruit.com/introducing- ... -resources

I believe you have the wrong setup in the Arduino IDE based on the errors you are getting, though. Perhaps try completely reinstalling the Arduino IDE and the Bluefruit BSP, as described here: https://learn.adafruit.com/introducing- ... d/software

From there, make sure that you have the right development board selected (ex. Tools > Board > Arduino Uno).

You should be able to compile any Bluefruit demo code at that point, and it's not obvious to me at all why you are getting the errors you are at build time except having an incorrect board selected (???). This doesn't appear to be a HW issue since compilation is completely independent of the HW itself.

If this is a school project, is there any assistance available locally to help you with the initial setup, since the problem seems to be there? Sorry I can't be more precise, but in the many thousands of theses boards we've sold this is the first time I've seen this issue.

I did uninstall ardunio and re-install again as well as the adafruit libraries im usibg Mega, so i made sure the connected board Mega. I also attached the picture of the AtI command. Still not working.

[ktownsend]

The HW is clearly functioning correctly, so it's purely a config issue.

I justed tested using Arduino IDE 1.8.1 on OS X, selecting Tools > Board > Arduino/Genuino Mega or Mega 2560', using the 'Factory Reset' sketch, and it compiles perfectly here:

Code: Select all

Sketch uses 6982 bytes (2%) of program storage space. Maximum is 253952 bytes.
Global variables use 450 bytes (5%) of dynamic memory, leaving 7742 bytes for local variables. Maximum is 8192 bytes.

I'll check if anyone else has any ideas why your specific setup if failing, but I truly don't have any idea at this point, but I'm 99.9% sure this is purely a local config issue and not the HW itself. :/

This is the code for blufruitconfig.h

Is there any thing I need to change for atcommand code with Mega board?

[adafruit_support_rick]

You're on a Mac? You can try deleting the Arduino15 folder.
First, close the Arduino application, and move it to the Trash.
Then, in Finder, open the 'Go' menu, and select 'Go to Folder...'
In the box, type ~/Library. That will open a new finder window to the Library folder.
In the Library folder, you'll see a folder called 'Arduino15'. Move that folder to the trash.
Now download and re-install the Arduino application. See if your compile issues have gone away.

[dina91]

I use Windows 7 not mac.There is no file called Arduino15.

[adafruit_support_mike]

The Arduino IDE has a folder named Arduino15 on all platforms. On Windows, it should be located at C:\Users\(username)\AppData\Local\Arduino15

Delete that folder, reinstall the board support packages, and see if that helps.

[dina91]

Still, I don' t see anything called Appdata. I also searched in the menu search for Appdata or Arduino 15, nothing pop up. I want to clarify that my Arduino IDE is running okay with the code I am using. But when I upload it with Blurfruit Uart Friend, the error appear.
