As an IQ programmer can I modify BLE transmitter power?

Former Member over 5 years ago

In our application I have a sensor complex mounted on a persons back; this is "connected" to our Garmin IQ app.

We have a constant chatter between the watch and our sensors and functionality relies on this link.

I have seen in test that we are seeing connection holes where the connection is lost for a period before being restored. I a 40minute test in the "wild" I did yesterday I saw approx 5 periods of significant connection loss of durations between 14seconds and 49 seconds (the worst).

The body is a significant cause of radio wave attenuation; could this be my problem; or it may just be black spots in the area I have tested.

I have the option to ramp up the BLE transmitter power in our sensor complex; at the hit of increasing battery drain; but do I have the possibility to ramp up the transmitter power of a garmin watch?

Any ideas of how to minimise the bad effects we are seeing (other than moving sensors closer to watch)?

You don't have the option from the CIQ side. Based on what I understand, you are seeing the same issue as is seen with a watch and music, where based on the location of the watch vs headphones. I have one pair that gets drop outs if my arm is behind my back, and another where if the receiver is set to be on the right side vs left side when the watch is on my left arm.

:-( Kind of thought that's what you would say Jim. Only solution I can think of is a bit of caching and delayed data transmission.

Or look at having the Ble antenna in a better spot, using something like a separate ble radio with a better antenna, so doing something like having the actual sensor detached from the unit and worn on the back, while the processor/ble is worn on the chest.
