Description

This data field connects to an ANT+ external (auxiliary) heart rate monitor, displays and records the data to a FIT file for comparison and analysis: heart rate, min/avg/max lap/session HR, HR zone, AntID, alias. If you like the app you can thank me by sending a beer: https://paypal.me/GavrielF and writing a positive review. If the DF crashes (IQ! icon) then try to disable the recording of some of the FIT fields. Garmin only allows 16 fit fields to be recorded and if other DF uses too many it can cause a crash. FAQ: https://t.ly/aIdTQ Support Forum: https://t.ly/K3kL Note: you shouldn't pair the HRM with the watch via ANT! (You can pair via Bluetooth) (To disable ANT pairing: Menu ≫ Sensors & Accessories ≫ [Your ANT HRM] ≫ Status ≫ Remove or Off) ### Terms - "internal", "watch", "WHR", "OHR" sensor is used for either the built-in wrist heart rate sensor or an external (ANT or Bluetooth) sensor that is paired and connected to the watch (Menu ≫ Sensors & Accessories ≫ [Your HRM] ≫ Status ≫ Connected) - "external" or "HRM" or "auxiliary" is used for any ANT sensor that is not connected to the watch but is broadcasting and the watch is receiving it's signal. It can be a chest EKG sensor or optical armband or even the training partner's watch that is set to broadcast HR on ANT (Menu ≫ Sensors & Accessories ≫ Wrist Heart Rate ≫ Broadcast During Activity ≫ On) Initially, the strongest external sensor's signal is picked up and remembered throughout the activity. To avoid tracking the wrong sensor (for example during a race where many people run with ANT HR sensors), the ANT ID can be fixed in the data field settings. ### Use cases - Comparing an auxiliary heart rate sensor (i.e: chest strap or armband) to the internal optical HR sensor of the watch - Compare two external sensors (one connected to the watch via ANT+ or BT vs one not connected/paired to the watch) to see the difference and analyse them - Monitor and record a training partner's HR for pacing during an activity. My device natively connects to my HR sensor and this data field connects to my friend's, so during the activity I can see how hard they are going while pacing in the front, and still - in parallel - see and record my own HR - Coaching: trainer can see the HR of the trainee - Monitor a horse's HR during a horseback ride ### Settings - Only connect to ANT ID - If set, then it will only connect to that device. Set to 0 to search and connect to the closest device. - Set name for connected ANT HRM - Enter an alias for the currently connected sensor. This alias will be saved & displayed in Garmin Connect in any activity recorded using this sensor. You can save multiple users. - Name - ANT ID - HR Zones - "u" - use user's HR zones | "m:{maxHR}" | "z:{minZ1},{maxZ1},{maxZ2},{maxZ3},{maxZ4},{maxZ5}" - Low/High HR Alert - alert when below/above given zone/HR - (0 - off | 1..5 - when below/above zone | 30..255 - when below/above HR) Enable alert screen: Activity(i.e: Run) Settings ≫ Alerts ≫ Add New ≫ Connect IQ Data Fields ≫ ANT+ HRM ≫ Edit data field settings? ≫ No The display format can be set using 2 format strings. The watch will automatically adjust the font size and place the 2 parts in 1 or 2 lines depending on the available space. Format for both parts: AntHR:{H}, AntZone:integer(i.e: 2):{Z},fraction(i.e: 2.34):{z}, AntName:{N}, OHR:{o} - Display format part 1 - i.e: "{H}" - Display format part 2 - i.e: "z{z}" - Show field label - Show HR zone gauge - Show HR zone color - color background according to zone - Delay Low HR Alert - don't alert on low HR for X seconds at the beginning of the activity FIT recording: If the data field crashes when you enter the activity, then disabling the less important fields can help. - Record invalid HR - when disabled "--" is displayed, 0 is recorded to indicate invalid HR (i.e: drop in connection, strap removed). When enabled invalid HR value is displayed, recorded to fit: flat line
