ESP-WROOM-32 built in antenna specification for CE certification

[kbw@zonith.com]

We are in the process of getting a solution with the ESP-WROOM-32 module CE certified and the test facility engineer asks for the follwoing:

Antenna specification for RF Testing (EN 300 328 (BT 4.0) EN 300 328(BT2.1 EDR)

I cannot find any documentation about such information like Frequency Range, Gain, Antenna pattern (radiation pattern), etc.

Could you please direct me to right documentation.

Thanks in advance
