OLED display with GT911 touch controller (gesture mode) how to use it

[up8051]

I have such Winstar OLED display (mono128x64, LCD controller SSD1309, touch controller GT911):

Display is connected to ATMEGA4809 by SPI and I2C
I can disply any data and use GT911 controller for recognize simple touch and relase.

GT911 controller has the ability to recognize gestures but I can't use it.
After sending command 08-switch to gesture mode (write to register 0x8046 and 0x8040) the panel does not react to any touch.
Data sheet for GT911 is very unclear about configure register related to gesture.
I tried to analyze Linux/Android driver but witout succes.

Has anyone used GT911 controller and knows how to use gesture mode?

While i've not used this controller myself , I have seen a lot of it's code in the kernel,
Have a look at this file for some examples of gesture setup
https://github.com/shreshthtuli/Goodix-Gt9xx-driver/blob/master/gt9xx_android_driver_v2.8.0.2_20171214(1)/gt9xx_android_driver_v2.8.0.2_20171214/gt9xx_v2.8.0.2/gt9xx.c
 and then there is also this file which has some pre-set configs you can fire at the i2c and it will setup the device.
