Changing SensorID and Type during runtime

Dear All,

thanks very much for your help. Seems solved.

Changes to power sensor settings worked fine while HRM did not.

Comparing code, HRM init additionally was executing: sd_ant_network_address_set(ANTPLUS_NETWORK_NUMBER, m_network_key);

Setting changes seem to work fine on both sensors after removing network address setting.

Best regards, Andreas

Thanks Petter, I have tried this without success. What is the recommended API procedure to re-establish a broken link (EVENT_RX_SEARCH_TIMEOUT) or changing sensor settings (i.e. ID)?

I am looking for something like this:

sd_ant_channel_close(ant_channel);
sd_ant_network_address_set(ANTPLUS_NETWORK_NUMBER, m_network_key);
sd_ant_channel_assign(HRMRX_ANT_CHANNEL, HRMRX_CHANNEL_TYPE, ANTPLUS_NETWORK_NUMBER,HRMRX_EXT_ASSIGN); 4.sd_ant_channel_id_set(HRMRX_ANT_CHANNEL, sensorID,HRMRX_DEVICE_TYPE, HRMRX_TRANS_TYPE);
sd_ant_channel_radio_freq_set(HRMRX_ANT_CHANNEL, ANTPLUS_RF_FREQ);
sd_ant_channel_period_set(HRMRX_ANT_CHANNEL, HRMRX_MSG_PERIOD);
sd_ant_channel_open(HRMRX_ANT_CHANNEL);

Have you tried to unassign the channel with sd_ant_channel_unassign()?

My system is trying to receive ant data from different sensors. These sensors may differ in type, but for sure differ in ID. To switch from one to an other,I do close the channel and reopen channel with different settings. Sensors will work on first channel open after startup, but not on following attempts.

I'm unable to reproduce this. I'm using SDK8.1.0, SoftDevice S210 v4.0.1. I have

ant_channel_tx_broadcast_setup();
sd_ant_channel_open(HRMTX_ANT_CHANNEL);    
ant_channel_tx_broadcast_setup();

in \examples\ant\ant_hrm\hrm_tx
