I am limited to 150-180 bytes/s on the transfer speed when I write data from the STM32WB55 to a RPI with read and notify.
I have tested different timings for when the device poll and the advertising interval. Furthermore, I have tested with different buffer sizes between 8 and 22, and the data is corrupted if try to send more data than 22 bytes.

Result from a 30 byte uint8_t buffer of zeros: 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01.

Is this a config error? and can the speed be increased?
