    Hi Hiro,

    Regulatory settings is done via settings of country code. At appendix C of SWRU455 is a table of regulatory domain for country codes.

    For CC3235 device you can also manually control offset of power for 2.4GHz and 5GHz channels. This can be done via Uniflash software (see chapter 6.8 of this document).

    Hi Jan D-san

    Thank you very much for your reply.

    I have some addtional quesion for Insertion Loss.

    What the value to set for TX(DB) and RX(dB), Antenna Gain (dB)?

    For example, Channel = 36ch

    our Board with CC3235MODASF  TX -10 dBm, RX -65dBm

    Reference board TX 0 dBm, RX -40dBm    

    Insertion Loss

    U-NII1

    TX (dB) 10.0

    RX (dB) 25.0

    Antenna Gain (dB) 0.0

    Is it correct ? 

    Generally, how to get difference between reference specification and our bourd for Insertion Loss? 

    Best Regards,

    Hiro

    Hi Hiro,

    I am sorry, but I am not able answer your question. Please wait for answer from TI.

    But I am little bit confused. CC3235MODA have antenna on module but at LP you tested which antenna (SMD at LP or your antenna connected using uFL connector)?

    Hi Jan D-san,

    I'm sorry. I develop software on CC3235MODASF.

    I confirm nessary setting for software.

    Does your confusion mean the following?

    Because CC3235MODASF include antenna,

    LP setting is not required.

    Best regards,

    Hiro

    Hi Hiro,

    What is your reference board? It is LAUNCHCC3235MOD? I was just curious what antenna were used at LAUNCHCC3235MOD (SMD antenna at LAUNCHCC3235MOD or external connected to uFL connector). Different antenna type may to explain different measurement results (e.g. more directional antenna). Another explanation may to wrong PCB layout (e.g. ground below antenna at CC3235MODA).

    But for more detail answer please wait for TI engineer.
