ANT on PCA10056 and custom board ?

[RixtronixLAB]

Dear Members,

I want to run ANT+ code in my custom board,

It works well on PCA10056, I can upload softdevice and the code to custom board board,

but I didn't get any responses,

I have tried with code without softdevice, the custom board works well

Any ideas ?

Thanks

Hello,

Does your custom board have a 32KHz crystal mounted? If not, you have to make sure you select the internal RC oscillator when you enable the Softdevice. Otherwise, the Softdevice will enter an infinite loop waiting for the crystal to start.

The memory layout should be left as is.

Best regards,

Vidar

Hi Vidar,

Yes 32KHz crystal mounted on my custom board, how can I know it started ? thanks

Hi,

OK, thanks for confirming. The next step should probably be to try debuggin the application and see if the program gets past the ble_stack_init() function. If it does, it means the crystal has started.

I can not find that function in my app,

log_init();
    utils_setup();
    softdevice_setup();
	    //**Init I2C and EEPROM before ant started, in order toclear EEPROM before sensor start TEST**
	    ssd1306_init_i2c(SSD1306_CONFIG_SCL_PIN, SSD1306_CONFIG_SDA_PIN);
			eeprom_cmd_clear_distance(); 
	    //initialize time for distance saving
			m_speed_calc_data.acc_evt_time=0; 
	
    profile_setup();
	
	  create_timers();
	
							
	  /* Init systick driver */
    nrf_drv_systick_init();

That's my init code....

ble_stack_init() is named softdevice_setup() in the ANT examples, but it has the same function, which is to enable the Softdevice stack.

my UART is not running as well I connect P0.06 and P0.08 to external CH340, but I can not see any serial communication, how can I rectify it ? thanks

Hi Vidar,

The 32KHz and 32MHz crystal are soldered on board, are they automatically being used by CPU, or I need to define in code ?

Thanks

Did you manage to debug the application to find out if the FW hangs or crashes?

I can see in NRF LOG, it stopped at "RTC initialized".....what do I miss here ?

I tried with

E:\nRF5_SDK_17.0.2_d674dde\examples\peripheral\rtc\main.c, and it is with external LF,

it's working fine...

thanks
