Technical Parameters of ESP-WROOM-32

[Sai Teja]

Hi, I are using ESP-WROOM-32 in an application. Please provide the following details regarding ble transmission of ESP-WROOM-32.

1) modulation bandwidth ,
2) frequency channels and
3) data rate.
4) Tx Power

Can we change above parameters programatically? If yes, please tell how to change these values? If no, please tell what are the default values of the parameters?

I am using Arduino Core for ESP-32 for programming.

We need the information quickly, please respond as soon as possible.

Awaiting your reply.

I think *you* need to do some work; begin to reading the technical specifications!

Then post again when you have done that; and post a list of what you have read and if any questions still remain this is a good place to ask for help.

Hi,

For "frequency channels", if you mean changing the channel when ESP32 is advertising, please try to call this function.
TX power can be set by calling this function.
The other two parameters are given by the Bluetooth spec and cannot be changed.
Let me know if you have further questions. Thanks.

Hi ESP_Lvxinyue,

Thank for your information.

Please tell the default values of modulation bandwidth and datarate.

And regarding frequency channel , you referred function related to starting ble advertisement. I would like to know frequency channel for ble transmission.

Awaiting your reply.
