Thanks. The thread above is slightly different. it was asking for 40Mhz operation in 2.4G. My question is for 40Mhz on 5G. The data sheet said so but the command does not work
The datasheet does indeed state that the BCM43341 chip supports 40MHz channels. However this mode of operation is not fully supported in the WICED SDK.
Thanks for looking into this. We will not evaluate this feature at this point then.
