Occasionally while having my 20s connected to my SR10 connected to multipoint pairing (second phone) my radio transmissions come across like a Cylon robot - very distorted. The only solution is to reset everything - turning it all off and then on again. I had that problem too with my SMH-10. Cannot seem to find a triggering event when it occurs, but it has been very annoying over the years. Used different radios without success in eliminating the problem. Everything is paired correctly and I have done both factory resets and hard resets for both units in trying to eliminate the problem. The problem is frustrating as it is occasional in nature but crops up in the most unopportune moments making things very unreliable. Anyone with similar problems or a solution?

Brian Whitaker Same issue, multiple units, also seems random. Funny that my buddies talk about this audio distortions as 'cylon mode' and agree that power cycling the SR10 is the only way to reliably fix the issue. Digging through the tank bag w gloved hands to hit the tiny button on top plus the big button is frustrating and dangerous.
Sena -- I volunteer to help debug. I happen to be a wireless hardware engineer. Who is your BT vendor? CSR? Broadcom? -
ANDREW MISPLON Hi Ken and Brian
For what it's worth, I had some testing success with an SMH10R by pairing the phone under multipoint pairing (HFP) and pairing the SR10 as the phone (A2DP).
In normal pairing (SR10 under multipoint) I was able to recreate the robot voice issue reliably in a testing environment. In reverse pairing (SR10 paired as phone) I wasn't able to recreate the issue any longer.
However, this week my friend reported the robot voice issue even with the reversed pairing. So...if you're still using a SR10, perhaps give that reversed pairing a try.
(Ideally, we need Sena to make a new SR10 with Bluetooth 4.1 or BT 5 and not BT 2.1 released in 2007! I can dream.)
-
Brian Whitaker Andrew -- I never heard from Sena on this. I'll have to read up on the "reverse pairing" concept. You are saying that you could not reliably reproduce the problem, but you did have the problem in the field?
-
ANDREW MISPLON Using the SMH10R headset and pairing the SR10 adapter under multi-point pairing I could recreate the issue at home with two radios. I could recreate the reliably, every time.
Switching the SR10 from multi-point pairing to phone pairing reliably resolved the problem in testing. I could no longer recreate the issue.
All of the above said I've now had one report that my solution didn't work for a friend of mine this week.
It's pretty quick if you want to give a try, you'd clear all pairings on your headset. If you wanted to, you can clear all pairings on the SR10 by holding down the top button for 10 seconds, when it flashes red only, press the top button once more, the unit then shuts off. When you turn it back on, you'll have no pairings on the SR10 and can re-pair to your headset.
Or, I guess, you could just pair over the existing pairings.
-
ANDREW MISPLON For the 20s though, I think we might be talking about the first and second mobile phones. At least that's the case on the newer 10R headset. If that's the case, you could try pairing the SR10 as the first mobile phone and your phone as the second mobile phone.

Bruce Littlefield Hi all, I am having the same intermittent garbled transmissions with my sr10 hooked to my DWO-5 helmet. I believe I am tracking this down to a possible thermal problem with the sr-10. Just did a long ride from California to Boise, and in the cool weather it took 5 hours to fail, coming back it was hot and it failed in 6 minutes. Cycling power will bring it back for a while. Has anybody looked into a thermal related problem with this transmission issue?

ANDREW MISPLON Hi Bruce
I haven't noticed a relationship between heat and this issue occurring. Going off the Sena site it sounds like the DWO-5 has the same functionality as the SMH-5. You could perhaps try pairing your SR10 as the mobile phone, the first pairing slot (if it isn't already) to see if that helps. So far the most reliable Sena to Sena combination I've tested is the SR10 paired with a Sena 10R, the updated low profile headset not to be confused with the SMH10R headset.
(Currently, I'm using an Icom F52D paired with an SMH10R headset. There are one or two oddities like the radio needs to be turned on first but overall it's working well. It took some setting up in the Icom programming software but I got there eventually. The F52D outputs a shriek when paired with the newer 10R headset and held close to the headset when transmitting. I'm not sure if it's because of the FM radio in the 10R or the newer Bluetooth protocol.) -
Bruce Littlefield Thanks for your input andrew. As part of this thread, I think you mentioned that one of your friends did the reverse pairing but also had the transmission problem. Did I read that right, I think you were talking to Ken and brian. I'm going to try using a heat gun and slowly warm up the sr10 and if I get a garbled voice I'm going to put it on blue Ice and see if it goes away, it just seems that as the temperature increased, the failure mode increased. I've asked Senna about this, but I'm still waiting for the reply as far as whether it could be a thermal problem or not. I'm not sure they'll own up to it if it is a thermal problem, because it probably either means a heat sink problem or components internally are getting too warm, and that means a hardware recall.. I'll let you know what I find!

ANDREW MISPLON Hi Bruce
Sure, no problem.
Yes, we have heard the issue once using reverse pairing. The setup that time was the SMH10R and the 10R. Reverse pairing should either eliminate the issue or hopefully reduce how often it happens. It was recommended by Michael at Sena support in Germany. The downside is you lose the ability to play music with your phone and use Siri or similar.
Good luck with the thermal testing. Please, let us know how you get on.
Cheers :) Andrew

Bruce Littlefield Thanks Andrew for your feedback. Good to hear that Sena gave you that information as well. Only problem is I like music, navigation and CB because I lead a lot of bikes with cbs.. I'll let you know about my thermal test! Do you know how often this problem occurs on the sr10? Like sooner or later everybody has his problem or do I just have a marginal unit.
-
Bruce Littlefield Hi guys, I did a check for any thermal issues with the SR-10, I performed the following test:
I did a heat soak test, lasting a half hour, with an initial SR-10 case temperature of 72 degrees and slowly heated the unit to between 130 and 140 degrees. I let it soak for 10 minutes. I continued to transmit during the complete test with no voice degradation during transmission.
I suspect my problem is most likely not heat related. I have a Sena tech suggesting some resets and updates with my SR-10 and DWO-5 Sena helmet transceiver.

ANDREW MISPLON Hi Bruce
Thanks for posting your testing process and results, appreciate it.
Let us know how you get on with the software updates and resets.

ANDREW MISPLON Hi Bruce
Do you know how often this problem occurs on the sr10? Like sooner or later everybody has his problem or do I just have a marginal unit.
I have access to four SR10's. Using the SMH10R and SMH5 headsets, I can recreate the issue with all four SR10's I have access to. The issue doesn't occur using the 10R headset. I'm not sure if all SR10's encounter this issue, all of the units I have access to do with particular headsets.
-
Bruce Littlefield Thank you Andrew, that is a very good data point.. I have updated and reset both my helmet and sr-10, and we'll see what happens when I have a long ride...
-
ANDREW MISPLON That's a good place to start! Cheers for now :)
-
Bruce Littlefield Well Andrew, I believe I tracked the problem down to the pigtail cable.... No problems since I changed it out.....
-
ANDREW MISPLON Hi Bruce.
Thanks for the update.
I'm really glad to hear you've made progress! The SR10 cable to the radio can be really tricky as it ages. A friend of mine has gone through a few cables in the past. The issue is that they don't necessarily fail in an obvious way. My recommendation is to occasionally fiddle with the cable on both ends to see if it's causing the radio to transmit. The issue in our case was my friend's radio would transmit accidentally due to the cable failing and clog up the frequency. I didn't know about a potential cable link to the robot voice issue. Good to know!Cheers for now.

Bruce Littlefield You described the cable problem exactly! Exactly what happened, and exactly how I figured out the problem. It will be interesting to see if the robot voice situation occurs again, I'm hoping not. Thanks for your help!
-
Bruce Littlefield As a follow-up, I have used the sr10 with my ham radio VX 7r, and of course it has a different pigtail, and I never had the robot voice. Possibly indicating it's not the sr10 unit itself.

ANDREW MISPLON Thanks for the updates. Hoping everything stays working without issue! Good to know about your Yaesu and the SR10.
All the best. Cheers for now :)
