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.

I understand why that could be a bit confusing. I recommend you to use the ANT Message Protocol and Usage document in addtion to the SDK documentation.

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

I don't understand what you mean. sd_ant_network_address_set() assigns a network key to a network number. sd_ant_channel_assign() associates a network key with a channel through a network number.

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).

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().
