Module can't setup, breaks during initalization

[manuelburger]

Hello, I have the Adafruit nrf8001 breakout connected to an Arduino Uno. My code is as follows:

//
//  ancs_lcd.ino
//
//
//  Created by Luke Berndt on 8/24/14.
//
//
#include <lib_aci.h>
#include <SPI.h>
#include <EEPROM.h>

#include <notif.h>

Notif notif(10,2);
ancs_notification_t* current_notif = NULL;
uint8_t message_char = 0;

char wait = ' ';
unsigned long screen_update_timer = 0;
unsigned long backlight_timer = 0;
boolean backlight = false;
boolean connected = false;

void ancs_connected() {
    backlight = 1;
    Serial.println("Connected!!!");
    backlight_timer = millis();
    connected = true;
}
void ancs_disconnected() {
    Serial.println("Disconnected!!!");
    connected = false;
}

void ancs_reset() {
    connected = false;
    Serial.println("Reset!!!");
}

void ancs_notifications(ancs_notification_t* notif) {



     Serial.print (F("["));
     if ((notif->flags & ANCS_EVT_FLAG_SILENT) == ANCS_EVT_FLAG_SILENT)
     Serial.print(F("-"));
     else if ((notif->flags & ANCS_EVT_FLAG_IMPORTANT) == ANCS_EVT_FLAG_IMPORTANT)
     Serial.print(F("!"));
     else
     Serial.print(" ");
     Serial.print (F("] "));
     Serial.print(F("Notif #")); Serial.print( notif->uid); Serial.print( F(" ; from: '"));
     #ifdef ANCS_USE_APP
     Serial.print( notif->app);
     #endif
     Serial.println( F("'"));
     Serial.print(F("   category: "));
     switch (notif->category) {
     case ANCS_CATEGORY_INCOMING_CALL:
     Serial.println(F("incoming call"));
     break;
     case ANCS_CATEGORY_MISSED_CALL:
 Serial.println(F("missed call"));
 break;
 case ANCS_CATEGORY_VOICEMAIL:
 Serial.println(F("voicemail call"));
 break;
 case ANCS_CATEGORY_SOCIAL:
 Serial.println(F("social msg"));
 break;
 case ANCS_CATEGORY_OTHER:
 Serial.println(F("other"));
 break;
 case ANCS_CATEGORY_SCHEDULE:
 Serial.println(F("schedule"));
 break;
 case ANCS_CATEGORY_EMAIL:
 Serial.println(F("email"));
 break;
 case ANCS_CATEGORY_NEWS :
 Serial.println(F("news"));
 break;
 case ANCS_CATEGORY_HEALTH_FITNESS:
 Serial.println(F("health & fitness"));
 break;
 case ANCS_CATEGORY_BUSINESS_FINANCE:
  Serial.println(F("business & finance"));
 break;
 case ANCS_CATEGORY_LOCATION:
 Serial.println(F("location"));
 break;
 case ANCS_CATEGORY_ENTERTAINMENT:
 Serial.println(F("entertainment"));
 break;
 default:
 Serial.print(F("unknown: "));
 Serial.println(notif->category, DEC);
 break;
 return;
 }
 Serial.print(F("   title:    '")); Serial.print( notif->title    ); Serial.println("'");
 #ifdef ANCS_USE_SUBTITLE
 Serial.print(F("   subtitle: '")); Serial.print( notif->subtitle ); Serial.println("'");
 #endif
 Serial.print(F("   message:  '")); Serial.print( notif->message  ); Serial.println("'");


current_notif = notif;
message_char = 0;
backlight = 1;
backlight_timer = millis();

}

void eepromWrite(int address, uint8_t value)
{
eeprom_write_byte((unsigned char *) address, value);
}

void setup(void)
{

Serial.begin(115200);
Serial.println("Serial communication started...");

//print spi pins:
Serial.print("SCLK:" + String(SCK)); Serial.println("");
Serial.print("MOSI:" + String(MOSI)); Serial.println("");
Serial.print("MISO:" + String(MISO)); Serial.println("");

//Wait until the serial port is available (useful only for the Leonardo)
//As the Leonardo board is not reseted every time you open the Serial Monitor


//If things get really crazy, uncomment this line. It wipes the saved EEPROM information for the Nordic chip. Good to do this if the services.h file gets updated.
//After it is wiped, comment and reupload.
// eepromWrite(0, 0xFF);

Serial.println(F("Arduino setup"));
notif.setup();
notif.set_notification_callback_handle(ancs_notifications);
notif.set_connect_callback_handle(ancs_connected);
notif.set_disconnect_callback_handle(ancs_disconnected);
notif.set_reset_callback_handle(ancs_reset);

}

void loop()
{

    notif.ReadNotifications();
}

It is basically just the example code, without the whole LCD setup. I just put in a few Serial.prints to know when I successfully connected.

I am perfectly able to run the Nordic example with the app on my iphone; connecting, sending etc. no problem -> the module works

I have the pins connected as follows and hardcoded the respective pins as follows:

//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       = 1;

However on the Serial output on my laptop I just get the following outputs:

Arduino setup
[free SRAM] 643 bytes
Evt Device Started: Setup
Evt Device Started: Setup
Evt Command Response: : Error 82
Evt

or:

Arduino setup
[free SRAM] 643 bytes
Evt Device Started: Setup
Evt Command Response: : Command invalid in the current device state
Evt Unk Cmd: 6
Evt Command Response:

or similar, I have never been able to connect to my phone, I have tried to uncomment the lines to wipe the eeprom of the chip, but with no success.

Does anyone have any idea, what I am missing here?

Any help or advise, suggestions are greatly appreciated and valued!

I'm also having this problem. Working with the bluefruit nRF8001 chip and an arduino uno.
