ANT appears to be broadcasting but no radio data sent

[dlip]

I have a complex application utilizing ble and ANT on the nRF52832. Slave channels receive fine but a master broadcast channel I have setup does not appear to transmit (as verified by sniffing for the transmission). The same code standalone works fine. The EVENT_TX message is received at the correct frequency and sd_ant_broadcast_message_tx does not return any type of error code. The code below is setting up the channel:

static ant_channel_config_t   ant_channel_config_remote  = \
{                                                                           \
    .channel_number    = 1,                                  \
    .channel_type      = CHANNEL_TYPE_MASTER,                            \
    .ext_assign        = 0,                                   \
    .rf_freq           = 57,                              \
    .transmission_type = 5,                               \
    .device_type       = 16,                                  \
    .device_number     = 2,                                   \
    .channel_period    = 8192,                                   \
    .network_number    = 0,                                  \
};

uint32_t err_code = ant_channel_init(&ant_channel_config_remote);
APP_ERROR_CHECK(err_code);
//first message frame


char message[] = {2,0,0,0,0,0,0,0x50};



err_code = sd_ant_broadcast_message_tx(ANT_REMOTE_CHANNEL, 8, message);
  APP_ERROR_CHECK(err_code);

  err_code = sd_ant_channel_open(ANT_REMOTE_CHANNEL);
  APP_ERROR_CHECK(err_code);

Strange. How did you sniff?

[dlip]

Sniff was a bad word choice. I am using antware with frequency and period set to the above and setting all other information as wild card. I see the broadcast message fine when I use the same code standalone. Is there a simple way I can scope the dk board to definitively see whether it is transmitting? I do not have the board configured for current measurement and do not have a test probe with an sma connector. Any other ideas on how I could trouble shoot this? Everything is quite integrated and so it's difficult to just turn off certain modules....

I see. Not really. You are absolutely sure that you are not constantly resetting because of APP_ERROR_CHECK() called with an error somewhere? What do you mean by standalone? Do you mean that the slave and master work without BLE or that master work without slave and BLE? Would it be possible for you to share your complete project so I can test it here? What SDK and SoftDevice are you using?

[dlip]

Yes I am connected and debugging so would notice a reset and also conntected via BLE which sends data to the app and that connection is maintained. By standalone I mean that if I just create a bare project (for instance using the broadcast_tx example) and put in my code for the initialization and message broadcast I see the data fine in antware. I am using SDK 14.2 and SoftDevice S332 5.0. Yes how could I send the project to you?

You can edit your question and upload it there. If it is private you can create a case through your MyPage and nordicsemi.com. In that case, let me know what the case number is.
