Telemetry sensors (vario & current) not working together

[GoogleCodeExporter]

Which board (stock / gruvin9x / sky9x / Taranis) are you using?

Taranis x9d

What is your openTx FW version?

opentx-r2834

What is your openTx EEPROM version?

215

What's the problem 

When I connect the new FrSky VARIOMETER sensor alone to the Smart Port of X8R 
... telemetry data are well displayed onto the TARANIS
When I connect the new FrSky CURRENT 40A sensor alone to the Smart Port of X8R 
... ... telemetry data are well displayed onto the TARANIS

But when I connect both sensors ... then is no more telemetry data displayed 
onto the TARANIS

What steps will reproduce the problem?

1. Connect the 2 sensors via S.Port

What is the expected output? What do you see instead?

Expected : telemetry data of both sensors displayed

I have 2 setups using both the high precision vario and SPORT FAS-40 (one with 
the old square FAS-40, one with the new slim one) and they work fine together 
with the current openTx release version.
What exact sensors do you have and where did you get them? One or both may be 
badly configured so that both share the same physical ID and step over each 
other's communication.
But it's definitely not an openTx problem.

Thanks for feedback.  I'll investigate to check whether, for any reason, both 
are sharing same physical ID
