We are using LBEE5KL1DX Module with external antenna. Due to design and space constraints we are unable to use PCB antenna design used by LBEE5KL1DX Module for FCC ID and leverage the same ID in our application. Because of this we need to update the power table or power limits in NVRAM file to pass FCC limits with external antenna. Also we need to generate NVRAM file with updated power limits and program in the device.

Does Cypress has the utility to update Tx power in CYW4343W during FCC compliance testing and generate NVRAM file? Also kindly provide steps to flash NVRAM file in the device.

Murata doesn't support that kind of special request for broad market. Please contact your local Murata person to get further assistance. There are several way to pass FCC.

Could I ask that you reach out to Murata to discuss an equivalent antenna which leverages their existing certification via a Class 2 permissive change? If you must negate their certs completely with an entirely new antenna design, we would have to refer you to a Engineering Services partner that could assist with the re-certification process as that's not something we support within the broad market or on the community.
