Hi Kenneth, do you know which file/code is being used for handling an interrupt, if there's a ANT signal coming in ?

Regards,

Hi Kenneth,

Thanks for the reply,

I see :

/**@brief Function for printing speed or cadence page2 data. */
static void page2_data_log(ant_bsc_page2_data_t const * p_page_data)
{
    NRF_LOG_INFO("Manufacturer ID:           %u", (unsigned int)p_page_data->manuf_id);
    NRF_LOG_INFO("Serial No (upper 16-bits): 0x%X",
              (unsigned int)p_page_data->serial_num);
}

How can I print them out ?

E:\nRF5_SDK_17.0.2_d674dde\components\ant\ant_profiles\ant_bsc\pages\ant_bsc_page_2.c

Line 64

Kind regards,

I suggest to get the dongle I linked from www.thisisant.com, I am not familiar with the third party dongle you have. Likely you need to contact the manufacturer if you have any issues.

Hi Kenneth, thanks for the reply,

Which software for simulation and profile do you suggest ?

I saw some softwares in this link :

https://www.thisisant.com/developer/resources/downloads/

I have Cycplus ANT+ dongle

Best regards,

Hi,

Your questions are reaonable, but I can't analyse the code for these questions, it just take too much time.

I suggest you get yourself an ANT USB dongle, download the the ANT+ profile and simulation tools from thisisant.com https://www.thisisant.com/developer/resources/downloads/

Then play around with this, if something is unclear it might be best to ask this on www.thisisant.com, since they are responsible for the ANT+ device profiles.

Best regards,
Kenneth

Can I do this to determine the first value of rev_cnt ?

if((m_speed_calc_data.acc_rev_cnt  - m_speed_calc_data.prev_acc_rev_cnt)==0) 
	         
						 {	
             
                               convert_save(rev_cnt);							 
			
							 
							 
						 }

HI Kenneth,

Thanks for the reply,

How can we capture the first value from the transmitter (rev_count) ?

The flow :

Pedal rotate ==> wheel rotate ==> GSC10 on ==> Transmit values ++++++++++++> our 2 receivers are waiting==>

Gets value from GSC 10 the first time <--- which function in ant_bsc.c or other codes/files/functions reading this ?

Kind regards,

The message_counter is just a way for the transmitter to make sure the data pages are being sent at the correct rate and interleaved as specified by the ANT+ profile.

Hi Kenneth,

Thanks for the reply,

Yes it does work 1 receiver to 1 transmitter,

Which function in ant_bsc.c for determining the transmitter activity ?

"if there's a transmitter---->do this--->..."<-----

\nRF5_SDK_17.0.2_d674dde\components\ant\ant_profiles\ant_bsc\ant_bsc.c

I saw line 147 :

p_profile->_cb.p_sens_cb->message_counter = 0;

How can we determine the first signal received from speed and cadence sensor ?

Kind regards,

Hi,

I don't see any obvious reason why this should not work

Does it work if you have 1 receiver to 1 transmitter?
