Hi, first of all, thx for your great work!

Just tested v0.10 and the reported RPM stops around 3700-4000, it is spinning to slow by the sound of it.

After I have noticed that, I checked with v0.9 and reported RPM is around 32000 (empty 5S 1750KV), sounds right again.

ESC Config is on defaults.

Bluejay version: 0.10 (24 & 48 kHz)
ESC variant: C-H-40 (Mamba F405 MK2 Stack)
Bidirectional DShot: On
FC firmware: BF 4.2

If you need me to test something, I am up for testing.

Hi, thanks for the report!

That sounds strange, having the rpm protection setting very low could cause this, are you sure it was at default of 9x? If that's the case I will have to examine the C layout more closely.

@KingKone Can you confirm this happens with the default settings?

I'm using the same mamba f405 mk2 stack, and for me 0.12 (test1) has been working and flying perfectly fine on defaults.

@koen352003 Thank you for the report!

I don't know what could have caused this issue other than the mentioned setting, so it's strange using v0.9 would work - maybe the settings were not the same for some reason. Anyway, I think we can close this for now then.

Same here. Today, experimented 4x1 Mamba F40HV ESC with C-H-40, 0.12, 48 kHz, Bluejay (BETA) with 6S battery with success! Params:
