Hi Nordic,
I am trying now to create a star network, in which the central node is master of different slave channels. The idea is to configure and open different independent channels. However, the code gets stuck when I try to open the second channel. I put the code here to see if you guys can help, because I tried many different things and apparently I cannot move forward.
These are the parameters:
// Channel 0 configuration ---------------------------------------------------------------
#define ANT_ACK_CHANNEL_NUMBER_0 0x00 /**< ANT Channel 0. */
#define EXT_ASSIGN_NONE_0 0x00 /**< ANT Ext Assign. */
// Channel ID configuration.
#define ANT_ACK_TRANSMISSION_TYPE_0 0x01 /**< Independent channel . */
#define ANT_ACK_DEVICE_TYPE_0 0xFF /**< 0xFF for master - slave 0. */
#define ANT_ACK_DEVICE_NUMBER_0 0x00 /**< 0x10 for master. Devicewise. */
#define ANT_CHANNEL_PERIOD_0 16384 /**< 2 Hz */
#define ANT_FREQUENCY_0 66 /**< 2425 MHz */
// Miscellaneous defines.
#define ANT_NETWORK_NUMBER_0 0x00 /**< Default public network number. */
// Channel 1 configuration---------------------------------------------------------------
#define ANT_ACK_CHANNEL_NUMBER_1 0x01 /**< ANT Channel 1. */
#define EXT_ASSIGN_NONE_1 0x00 /**< ANT Ext Assign. */
// Channel ID configuration.
#define ANT_ACK_TRANSMISSION_TYPE_1 0x01 /**< Independent channel . */
#define ANT_ACK_DEVICE_TYPE_1 0x8F /**< 0x8F for master - slave 1. Pairing bit 1. */
#define ANT_ACK_DEVICE_NUMBER_1 0x01 /**< 0x10 for master. Devicewise. */
#define ANT_CHANNEL_PERIOD_1 16384 /**< 2 Hz */
#define ANT_FREQUENCY_1 66 /**< 2425 MHz */
// Miscellaneous defines.
#define ANT_NETWORK_NUMBER_1 0x00 /**< Default public network number. */
And here the function that sets them up:
static void ant_channel_tx_acknowledge_setup(void)
{
uint32_t err_code;
ant_channel_config_t acknowledge_channel_0_config =
{
.channel_number = ANT_ACK_CHANNEL_NUMBER_0,
.channel_type = CHANNEL_TYPE_MASTER,
.ext_assign = EXT_ASSIGN_NONE_0,
.rf_freq = ANT_FREQUENCY_0,
.transmission_type = ANT_ACK_TRANSMISSION_TYPE_0,
.device_type = ANT_ACK_DEVICE_TYPE_0,
.device_number = ANT_ACK_DEVICE_NUMBER_0,
.channel_period = ANT_CHANNEL_PERIOD_0,
.network_number = ANT_NETWORK_NUMBER_0,
};
err_code = ant_channel_init(&acknowledge_channel_0_config);
APP_ERROR_CHECK(err_code);
err_code = sd_ant_channel_open(ANT_ACK_CHANNEL_NUMBER_0);
APP_ERROR_CHECK(err_code);
ant_channel_config_t acknowledge_channel_1_config =
{
.channel_number = ANT_ACK_CHANNEL_NUMBER_1,
.channel_type = CHANNEL_TYPE_MASTER,
.ext_assign = EXT_ASSIGN_NONE_1,
.rf_freq = ANT_FREQUENCY_1,
.transmission_type = ANT_ACK_TRANSMISSION_TYPE_1,
.device_type = ANT_ACK_DEVICE_TYPE_1,
.device_number = ANT_ACK_DEVICE_NUMBER_1,
.channel_period = ANT_CHANNEL_PERIOD_1,
.network_number = ANT_NETWORK_NUMBER_1,
};
err_code = ant_channel_init(&acknowledge_channel_1_config);
APP_ERROR_CHECK(err_code);
// Fill tx buffer for the first frame.
ant_message_send();
// Open channels.
err_code = sd_ant_channel_open(ANT_ACK_CHANNEL_NUMBER_1);
APP_ERROR_CHECK(err_code);
As I said, I get stuck at the second ant_channel_init.
Thanks for the help!
Regards.
