I have 4 dys XS 20 amp esc's all flashed to Revision 16.1 on BlHeli software. Blheli S AH 70 Multi

In Beta flight, under Configuration, there is a drop down box for choosing the esc/motor protocol.

The default that shows up is PWM. I want Multi, instead.

When I change it to multi and hit save, the system beeps and reboots. But when I reopen the configurator the same, PWM is the listed protocol. It seems like the Beta Flight is reading PWM from the esc's. Am I missing something the BLHeli settings?

Much Thanks,

Willie

What version of betaflight and gui? I had similar problems that the changed variables didn't save, when I had betaflight flashed with cleanflight gui and tried to use betaflight gui. This was at the time betaflight gui was released. The fix for me was to flash the board with the latest betaflight and use the latest betaflight gui.

Like Oyvinla said, it sounds like the settings are not saved. ESC detects signal from FC, and doesn't work the other way round for betaflight/BLHeli at this stage.

I have Betaflight 1.8.3

I tried to flash the piko blx fc and it wouldn't. So I watched a you tube video from Furious rc about another way to accomplish it. After using Zadig and the other complicated instructions, it opened.

 But, now I realize, it never did flash where you see the colored band go across the screen . It just opened and I set all the parameters in cleanflight. I hate to think I will have to tear into my build to short the boot pins and reflash. Any ideas? Maybe the little piko blx was flashed at the factory? As I said, I never did have to flash it, it just opened per the Furious rc instructions.  

  I did go back to blheli and check to see if all my esc's are the same settings and they are. Still, I can't get Multi to stick in the motor/esc protocol.

  Thanks for your patience and help,

Are you sure it came with betaflight pre installed and not cleanflight? I did a quick bing search (I'm in transit in China, so no Google here ) and on their website it says that it is flashed with cleanflight and betaflight fw. I find that a bit strange and I assume that there is something wrong. If your fc is flashed with cleanflight and you are using betaflight gui, you can get these sort of problems. I believe that the variable names in the code doesn't match up, that could be the reason why it doesn't save the settings

I think that Betaflight 1.8.3 is the gui version. If you write dump in the cli, you will get the cleanflight or betaflight version for the fc

oyvinla,

  You are very kind. I just wrote dump in the beta flight cli and it shows I have betaflight moto lab 2.8.1     I assume that means I do not need to reflash the fc.

  In blheli, I got all the esc's running the motors the correct direction and all numbers balanced with each other. In the motor tab in blheli and in beta flight, the motors perform correctly, but when I put on props and armed the board the little quad went full throttle and flipped over. I immediately disarmed it..

  I love this stuff when it works and when it doesn't, it's such a mystery. I know there is just something simple that is illuding me.

Happy travels in China,
