Arduino BLE micro and connection problem with I2C

Please post it as a new question and look at the appendix for the error code 0x83. 0x83 says, ACI_STATUS_ERROR_DEVICE_STATE_INVALID , which means that this depends on the command that you are sending, so you need to post a log of the list of commands and events that are being sent over the SPI. ( This is usually obtained by setting the debug parameter using the lib_aci_init() to true. The messages between the nRF8001 and the microcontroller are then printed out on the Serial port. ) If you suspect the WiFi , try it with a different phone, but for phone related issues always post the OS and OS version. However please post this as a separate question.

I too was having the problem of BLE getting disconnected. I'm using BLE shield from Red bear lab as the slave with Arduino Uno as the master. I was getting an error saying ACI Evt Pipe Error: Pipe #:4 Pipe Error Code: 0x83 Evt Disconnected/Advertising timed out It works flawlessly when I switch off the WiFi on my Moto G2 phone and check. I'm not sure why this problem would be occuring because of WiFi, if anyone having any idea, if would be great if you can explain

Thank You.

@Star Detroyer, thank you very much. I have moved in a new question here: devzone.nordicsemi.com/.../

Can you get me a debug trace ? This is usually obtained by setting the debug parameter using the lib_aci_init() to true. The messages between the nRF8001 and the microcontroller are then printed out on the Serial port and hopefully that can give us more clues.

If you cannot get the debug to work, you an also perhaps print the full contents of the ACI Disconnected message so I can understand this better.

You still have not pointed out the device that is used to connect to the blend micro, that may also hold some clues.

I have marked as Accepted answer because you perfectly explained what the error code is and and point me that was not I2C problem but I still have the same issue with the Hello World Sketch and echo.js receiver

It happens also with the Hello World sketch: github.com/.../HelloWorld.ino after 6 minutes

Sounds reasonable. But so.. why does the "Evt Disconnected/Advertising timed out" occurs? I've tried with nothing wired to the board sending fake data and.. just the same problem

You can look at the nRF8001 data sheet to see the meaning of Error code 0x83 . The codes are listed in the appendix, 0x83 means "ACI_STATUS_ERROR_DEVICE_STATE_INVALID". The likely reason is that you continued to attempt sending even after the connection to the peer device was lost.

I have also tried with BLE Controller Simple Chat Example from ReadBearLab.com v2.0 and.. same problem

@Star Destroyer: it's not an I2C problem, I've tried without the sensor and the problem persists. I'm using this to receive: github.com/.../echo.js I'm correctly receiving and then the connection goes in timeout

Hi! So, I'm using some piece of code from this Hello World RBL_nRF8001 Example to ble connection and then I'm using a node.js module as receiver. The error comes up after some data is correctly received and used. The receiving is not a problem. What does exactly Pipe #:3 Pipe Error Code: 0x83 means?

Which example are you using on the blend micro ? I do not think that the BTLE chip has an issue. It is continuing to advertise for 20 to 30 seconds and then it times out as there is nothing connecting to it.

Can you point at the application that you are using to connect to the Blend micro board ?

I suggest that you use the Android master control panel app to connect to the Blend micro board and test it.

I have measured it and it was 3.8V before connecting it. Anyway I have plugged though VIN pin in the Arduino and should be ok for the specs: Input Voltage: 5V (USB), 3.3-12V (VIN)

A LiPo battery with a nominal voltage of 3.7V probably has a voltage of 4.2V when fully charged. 4.2V might very well damage the chip.
