Very poor RSSI when changing from ACCST to ACCESS

After flashing some of my R-XSR receivers from ACCST to ACCESS 1.1.3 (Taranis SE 2019 firmware 1.13) there has been a SIGNIFICANT drop in RSSI and I am getting a RSSI alarm (set at 40) when only 10 yards away in Range check mode.

When I reflash the R-XSR back to ACCST the range goes back to normal. I have the same results with several receivers. Have I missed something or is there a serious problem with the ACCESS 1.13 firmware?

Currently I am unable to use the receivers with ACCESS firmware

I am not aware of any issues with Access and the problems you describe.  All of my Access equipment is performing faultlessly.

Hi Cliff,

many thanks for your input, I have tried 6 x R-XSR receivers and they all become virtually DEAF when moving from ACCT to ACCESS.

I am sure that my X9D Plus SE 2019 transmitter is OK as the RX6R receivers I have work well with ACCESS

The RSSI levels on ACCESS read alot lower, Frsky advised to change them to:

Low alarm: 35

Critical alarm: 32

I have done this with all my Access receivers now.  It does make difference!

 

Also if you alter the precision of the altimeter censor from o.o to 0.--  The readings are far more stable!

Do you have a source for that matter?

 

I have the same issue as the author of this thread. I own:

- X-Lite S transmitter, with latest ACCESS firmware (EU-BLT)

- R-XSR with latest ACCESS F.Port firmware (EU-LBT)

- G-XR8 with latest ACCESS firmware (EU-LBT)

 

Comparing the two receiver in exactly the same circumstances:

1 meter from receiver: R-XSR: 75, G-XR8: 99

standing in the room next door: R-XSR: 44 (low signal warning already in 5 meters), G-XR8: 86

 

I did do a range test with the R-XSR and I've gotten the first failsafe in 40m, which is not that terrible. But still, G-XR8 is also an ACCESS receiver, but yet it's RSSI reports are just fine. How do you explain that? And should we really set our warning lower? 32 db is very silent, there's not much leeway after that.

Have you read my post?

Your claim is incorrect, because on G-RX8 (ACCESS) they read just fine! 

 

Can you show me a source where FrSky released that recommendation? There's nothing about that in my instructions or anywhere on their page (that I could find).

Firstly it is not my "Claim" as you say.

Frsky told all the dealers to issue this info.  I have done it with all my receivers (G-RX8) and it has made a difference!

Okay, thank you for your information about the source of this claim. 

What do the others think about that? To me it seems very fishy. Since they just said that ACCESS reads lower values, and this is not the case with all ACCESS receivers. My assumption is that R-XSR's ACCESS firmware is faulty. So hopefully that means that RSSI values are wrong and not that range is also affected.

I think I'll have to do some driving to really test out the full range of the two receivers I have.

FrSky have done some tests on the RXSR and will release new firmware in a weeks time

Thanks for that information too! Can you tell us something more? Especially, will this fix the RSSI levels or is the range affected also?

I'm only asking to know, whether I should be more careful when using this RX? Currently I don't really have the confidence that other receivers give me. BUt if you say that only the numbers are off, then I can just ignore the warnings.

The RSSI is not going to affect the performance of the receiver!  It is only telling you the level of the transmittion of signal for telemetry.
