I have more or less the same problem with the Rally xc100 reporting power and cadence to my fenix 5. the connection is unstable with drops in the power and cadence data. What to do?

it is not the same issue as Shane posted originally. where is your F5 during the bike ride? on your wrist, or on the handlebar? which type of battery do you use? ( CR1/3N or two LR44/SR44)

I have the F5 on my wrist, heart rate measurement  works flawless. The XC100 has a CR1/3N battery.  I also have a Wahoo Elemnt on the handle bar, this cycle computer measures  the power from the pedal correctly.

I have tried if switching off the wahoo helps, but there is no difference. The X5 still has many drops in the XC100 measurements.

Could it be that simple that the F5 antenna isn't sensitive enough despite the short distance , less than one meter?

OFC that the HR measurement from HR belt is works "flawless", because that has a so-called "error correction" and if there is a signal dropout , it holds the last known value for long period so it is just HIDING the drop issue... (the powermeters have no such a correction, obviously.) The problem is the weak antenna in the F5, your wrist is decreasing the signal strenght heavily, the watch must be faced inside on your wrist or try to put on the handlebar onto a mount. or try to pair your XC100 via Bluetooth to the F5 (maybe that signal is a bit stronger), disable the ANT+ type , and check again. 

hi Luko

I tried your suggestion an faced the F5 down towards the XC100. To my surprise this resulted in a huge improvement, almost no  drops in the power measurements and the few drop were very short.

I've have had this issue up at garmin-support for months , but there is little help from their side though they must be aware of the issue.

I'll try BT as well, you never know.

Thanks so far for your help.

Face the Fenix 5 down towards the XC100 worked for me as well. Before massive drop outs. Afterwards no drop out anymore.
