Hi,
all worked well until this morning, when my 840 updated to 21.16.
See below the chart from Assioma BLE - periodic disconnects every ~100s
Has anybody experience similar and managed to find a workaround?
Thanks

Kinda the opposite. My crank spindle PM kept disconnecting and reconnecting every 10-20 seconds on ANT+ and I had to switch to BT to get it to stay connected. I haven't tried it again since just updating to 21.16 so don't know if it's fixed or not. Crank ANT+ continues to work fine on my 820, which can't do BT anyway.
I can confirm no drop-outs using ANT+ connection with Assioma.
Two things still bugging me:
(I removed the sensor from 840, powered it off/on, re-added sensor .. no change, still have to manually connect each time )
But at least it works during the ride - hopefully it stays like that
