ANT network number

[Ck]

I'm using nRF51422-QFAA E00 with S310, nRF51 5.2.0

When I configure ANT channel as a Master with Network number 0, all works OK. But if I try to set different network number I can't see any packet in the air.

For communication scan I'm using ANTware-II with ANT USB stick. I have also another module which use 2 Tx channels at once with different channel number and network numbers (same channel configuration as in my project) and I can see both in Scan Mode. But for nRF module I can see packets in that tool only if they are configured with channel 0 and network 0. So I don't think it's a PC tool bug.

Is this module restricted just to use network number 0 ?

EDIT: Same behaviour even if I use channel number non 0. All err_code passed with success. sd_ant_active() says ACTIVE.

Code:

err_code = sd_ant_channel_assign(ANTPSU_CHANNELNR_FORK, 
                                     ANTPSU_CHANNEL_TYPE_FORK, 
                                     ANTPSU_NETWORK_NUMBER,
                                     0);
if(err_code != NRF_SUCCESS) err = (1<<0);
		
err_code = sd_ant_channel_id_set(ANTPSU_CHANNELNR_FORK, 
                                 U16_NVM_ANT_Dev_Nr, 
                                 U8_NVM_ANT_Dev_Type, 
                                 U8_NVM_ANT_Trans_Type);
if(err_code != NRF_SUCCESS) err |= (1<<1);
		
err_code = sd_ant_channel_radio_freq_set(ANTPSU_CHANNELNR_FORK, ANTPSU_RF_FREQ);
if(err_code != NRF_SUCCESS) err |= (1<<2);
		
(void)sd_ant_channel_period_set(ANTPSU_CHANNELNR_FORK, ANTPSU_MSG_PERIOD_FORK);			
		
(void)sd_ant_network_address_set(ANTPSU_CHANNELNR_FORK, network_key_antp);			
			
err_code = sd_ant_channel_radio_tx_power_set(ANTPSU_CHANNELNR_FORK, RADIO_TX_POWER_LVL_3, 0);
if(err_code != NRF_SUCCESS) err |= (1<<3);

err_code = sd_ant_broadcast_message_tx(ANTPSU_CHANNELNR_FORK, 
                                       sizeof(m_tx_buffer), 
                                       m_tx_buffer);

This should work. Could you edit your question to include your testing method?

Edit: Sorry for being unclear, how are you testing that no packets are sent/are on the air?

Edit2: Could it be that you are using ANTPSU_NETWORK_NUMBER in sd_ant_channel_assign(), while you are using ANTPSU_CHANNELNR_FORK in sd_ant_network_address_set()?

Also, in C:\Keil_v5\ARM\Device\SDK5.2\nrf51422\Board\nrf6310\s310\ant_hrm\hrm_tx sd_ant_network_address_set() is called before sd_ant_channel_assign().

Yes exactly "through a network number". I was just confused with description in SDK reference where term network key is used directly.

Yes, without that document the API is partly not understandable. The ucTransmitType parameter from the sd_ant_channel_id_set() function is for example nowhere in the SDK documentation documented.
