Radio setup: lost of time

Post by Raythegreat »

Hi,

I have the Taranis X9D and the latest openTx firmware 2.2.1.
In my radio setup I have lost the time and date a few times since I updated in the 2.x.x versions.

Today my date was at 1970 with the wrong day time as well.

I have corrected the time and date a few times since the last year.

BTW: I have not removed the Tx batteries and they were never fully discharged. The Taranis TX works fine otherwise.

Any reason why this can occur? A wrong settings?

Thanks,

RTG

Update on the timer problem.

Now my Taranis cannot keep the time anymore after every power off and back to power on.
The date is always reset at 1970-01-01 and time at 00:00

What can be the problem?

How old is the radio? There is a small lithium battery on the main board that keeps the clock running when the radio is powered off. If the radio is quite old, this my need replacing.

Hi Mike,

Yes indeed Mike, the RTC Lithium battery is almost dead. Need to change it. It is the CR1220 3V.
My Taranis has 5 years so it is about time.

Thanks

I have this same problem... same reset date/time....
I hadn't noticed when it started, but it was at least 'months' ago.

I changed the RTC battery and it still does it.
1970.01.01 00:00
Every time you power it off then back on (whenever later).

Whether it flukes timing that is began on a certain OpenTX version or not I don't know.
I have 2.2.1 2018-01-24

I have the same problem. Replacing the battery did not help. I found discussion for an older Taranis radio (2015-2016) about fixing a similar problem with “beefing” up a capacitor. Can’t find a similar one on my x9d.
Any ideas?

Ditto here :| Early X9D but also Horus X12S Beta, professionally upgraded by vendor. Both running Opentx v 2.2.3, original PCB batteries.

As a test, you could try flashing ersky9x (after backing up your existing firmware and EEPROM).
I have some code in that puts the processor to sleep on shutdown so it cannot affect the RTC.

Both an early X9D and a beta horus could be expected to have their batteries dead by now.

Funny, all my radios still have the first battery.. And that includes my 9XR-PRO that is older than any of those radios.. Do they use lower capacity batteries?

Mine too but some people previously reported empty batteries after a year or so, so they could totally have been using cheapo batts on some batches.

Hi all,

My taranis RTC date and time problem was immediately fixed then I changed the battery. My Taranis had 5 years.

Kilrah is right, some batteries are cheaper than others and are worse, not up to their 100% capacity at shipment so the problems may occur at any time.
