Blutooth: Transparent UART mode possible?

[mabies]

Hi,
today we use another vendors BLR modul in a so called transparent UART mode.
This modul is initialized via some AT commands and acts like a UART, where one can just drop bytes in and these bytes show up at the output of another modul.
Or just between a Smartphone and this BLE modul.

Does ESP has something similar?

Thanks!
