Hi Chi-hsien Lin,
Forcing the pktengine rate before starting it seems to solve my issue.
Thanks!

Hello,
We are having the very same issue using a custom imx6ul board & Murata 1BW. (Same errors messages, ...).
We tried different versions of the BCM43340 firmware available on the "Quick Start with iMX6 Ultralite EVK and Mass Market Modules" page.
Thanks !

Hi kevin_2235601,
Could you please try forcing the rate before the packet engine and see if it still fail?
For example, forcing to mcs 7 -
wl nrate -m 7
Thanks.

Thanks for confirming.
Could you please share how you know about the packet engine command? I would like to make sure the related document gets updated so people will not run into this again in the future.

I was using a Murata document called "Example Subset of WL Tool Commands & RF Transmit Test Sequences" along with some scripts we used to certifiy another product (with a Murata Type ZP).
I don't think the "Example Subset of WL Tool Commands & RF Transmit Test Sequences" needs an update as the packet engine rate is always set before the start of the packet engine on the available examples. We were just doing it wrong on our scripts.
Thanks !
