Hi Yang,

You can change the max_pwr_db_val to required max value and then set the desired tx power using API wiced_bt_dev_set_tx_power(). There is no need to use a modified cgs file.

Hello Yang,

By 'output setting values', would you please describe which parameters you are talking about? Also, what do you mean by measurement conditions?

Sorry for cutting in.

I'd like to know how to configure the power class 2 for CYBT-343026-01 in WICED Studio 6.4.

I think we should set 2 to max_power_db_val in wiced_bt_cfg_settings_t.

Is it correct ?

And, is there anything setting what we need to do ?

Hello MaMi_1707981​,

max_pwr_db_val parameter is to set maximum power level, therefore it is set to 12 in application.

I don't think you need to set any other parameters for class 2 power measurement.

Hello SheetalJ_96,

For power consumption and backward compatibility for previous products, we would like to use it as "CLASS 2".

If max_pwr_db_val = 12, does the power class become 1 ?

My sincere apologies Yang & MaMi_3520196, I would like to correct my response.

For class 2 power measurement, you need different configuration file (.hcd). The one provided in WICED is for class 1.

Please check thread- How can I set the 20706 to class2?

Hello SheetalJ_96,

I would appreciate that you show the link.

I will ask local FAE it.

Hi SheetalJ_96,

We confirmed with local FAE.

The current version( WICED Studio 6.4) does not require a different configuration file (.hcd).

The maximum output can be changed by changing the value of max_pwr_db_val.

Is this correct?

Thanks,

Yang
