Cannot connect to phone (does not advertise?)

[adamzaninovich]

Hi, I'm trying to get this library to work with an Arduino Micro, an Adafruit nRF8001 Breakout and an OLED 16x2 display. I removed the code from the example that was specific to the lcd shield used in the original example, and I do see the disconnected icon flashing in the corner of the display, but I can't get the project to show up on my iPhone under the bluetooth settings.

I've tried both iOS 7 (iPhone 5) and iOS8 (iPhone 6). I also pulled the latest library code as of a few hours ago (Fixed for iOS 8 - dff14e9)

I'm not sure what else to try. Any ideas? Any help would be greatly appreciated.

That’s awesome, definitely let me know how it goes. There are a couple things you might want to try. In Notif.cpp there are the lines around 793 that handle the setup of the nRF8001. I haven’t used the breakout board. Right now it is setup to use the SPI pins. You might be using different pins, so probably best to hardwire everything in there. Also, if you have anything stored in EEPROM, try clearing it out. Try uncommenting line 218 in the .INO file: EEPROM.write(0, 0xFF);

Since it is not showing up on the iOS, there is some basic stuff not working. I would look into the library files. Turn on the logging in Notif.cpp and see if there are any clues there.

Thanks! I will try all that and report back.

[adamzaninovich]

I was able to get it to work!

I had to edit the code in notif.cpp around line 799 and tell it to use the reset pin and interrupt mode:

aci_state.aci_pins.reset_pin              = 9; // was UNUSED
aci_state.aci_pins.active_pin             = UNUSED;
aci_state.aci_pins.optional_chip_sel_pin  = UNUSED;

aci_state.aci_pins.interface_is_interrupt = true; // was false
aci_state.aci_pins.interrupt_number       = 1; // (on the Micro/Leo, pin2 is int1) was UNUSED

[robotastic]

Great to hear!

That looks really slick too. Now I want to get an OLED.

I will add a section to the readme.md

Actually, if you get a chance to try it out with iOS 8, can you test something?

When I reset the arudino / ble board, my iPhone connects and sees it, but ANCS isn't turned on and it doesn't work again until I turn bluetooth off and on in iOS. Does it work for you?

let me know if you come across any bugs.

[M0dusFRee]

I have the same problem. My phone not detect any new bluetooth device. I have iOS 8 on iPhone 5. I'll try the new version you have uploaded and see if the problem is corrected. I use an Adafruit nRF8001.

Thanks for de code!

[M0dusFRee]

which version of Arduino are you using? 1.0.5, 1.0.6 or 1.5.7 BETA?

[robotastic]

I am using 1.0.5 - what are you using for Bluetooth LE HW? Make sure you have all the pins declared correctly. With the shield the req and redy pins are settable, so make sure you are passing your config. Also try uncommenting the line that clears the EEPROM on the arduino. You could have something funky there.

Im having problems whilst using the Red Bear Labs shield. The jumpers are set to REQN = 12 and RDYN = 11. I have then set these values in the Arduino sketch and in the notif.cpp file accordingly. My Ipad (ios 7) doesn't see the Arduino and shield as a bluetooth device. I have tried clearing the EEPROM but no change.

Any help would be greatly appreciated.

Hi I am trying to reproduce the connection with an iphone 6 plus (ios 8.2) and the nrf8001 from adafruit and I couldn't get this work. (I am using IDE 1.0.6)

I can't even find the bluetooth module under the devices section on the iphone setting.

Here is my Arduino code, I am trying a simple code at least to detect my bluetooth with my phone

#include "lib_aci.h"
#include "SPI.h"
#include "EEPROM.h"
#include "notif.h"

Notif notif(10,2);

void setup()
{

  Serial.begin(9600);
//  EEPROM.write(0, 0xFF);
  notif.setup();
  notif.set_notification_callback_handle(ancs_notifications);
  notif.set_connect_callback_handle(ancs_connected);
  notif.set_disconnect_callback_handle(ancs_disconnected);
}

void loop()
{
  notif.ReadNotifications();
}
void ancs_notifications(ancs_notification_t* notif) {
  Serial.println('1');
}
void ancs_connected() {
    Serial.println('2');
}
void ancs_disconnected() {
  Serial.println('3');
}

And I modified the Notif.cpp line:795

//Tell the ACI library, the MCU to nRF8001 pin connections
    aci_state.aci_pins.board_name = BOARD_DEFAULT; //See board.h for details
    aci_state.aci_pins.reqn_pin   = 10;            //The REQN and RDYN jumpers are settable, make sure this is the same
    aci_state.aci_pins.rdyn_pin   = 2;
    aci_state.aci_pins.mosi_pin   = 11;
    aci_state.aci_pins.miso_pin   = 12;
    aci_state.aci_pins.sck_pin    = 13;

    aci_state.aci_pins.spi_clock_divider      = SPI_CLOCK_DIV8;//SPI_CLOCK_DIV8  = 2MHz SPI speed
    //SPI_CLOCK_DIV16 = 1MHz SPI speed

    aci_state.aci_pins.reset_pin              = 9; //4 for Nordic board, UNUSED for REDBEARLABS
    aci_state.aci_pins.active_pin             = UNUSED;
    aci_state.aci_pins.optional_chip_sel_pin  = UNUSED;

    aci_state.aci_pins.interface_is_interrupt = true;
    aci_state.aci_pins.interrupt_number       = 2;

Can anyone help ? (I did the reset thing and still nothing...) Thank you

[robotastic]

@DokRaphael I would double all the pins you put down. Are you using pin 2, twice? Are you able to get the Nordic examples running? https://github.com/NordicSemiconductor/ble-sdk-arduino My code is based on that.

[robotastic]

@ece00244 Did you ever get things working?

[DokRaphael]

@robotastic I did pull again and updated to 8.3 and now it works. I think that ios 8.2 has a problem with pairing with new devices.

Now I can pair with my iPhone but it disconnects right away with a error code :

Evt Command Response: : Error 8D

and sometimes

Advertising started. Bonding. Dissconnect status: 3
BTLE status: 24
Evt Command Response: : Success!
Bond

[DokRaphael]

Finally i did "forget this device" on the iphone settings and paired it again, now it works ! thank you !
