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);

Thanks Petter, you are right I was using wrong parameter in sd_ant_network_address_set. Now it's working OK. BTW you are not right with sd_ant_channel_assign, although reference says [in] ucNetwork is an unsigned char (1 octet) denoting the network key to associate with the channel. there is no network key but network number (also in Nordic examples net number is used).
