Ok, I found the solution. I use bad Python program. Now I found the good one, all works! Thanks

# This example demonstrates a UART periperhal.

# This example demonstrates the low-level bluetooth module. For most
# applications, we recommend using the higher-level aioble library which takes
# care of all IRQ handling and connection management. See

# Helpers for generating BLE advertising payloads.

# A more fully-featured (and easier to use) version of this is implemented in

# Advertising payloads are repeated packets of the following form:
#   1 byte data length (N + 1)
#   1 byte type (see constants below)
#   N bytes type-specific data
