#83063 I have problem, that there is not "ready" after start. I have only in 74880bps:

ets Jan 8 2013,rst cause:1, boot mode:(3,6)

2nd boot version : 1.7(5d6f877)
SPI Speed : 40MHz
SPI Mode : QIO
SPI Flash Size & Map: 16Mbit(512KB+512KB)
jump to run user1 @ 1000

rf cal sector: 507
freq trace enable 1
rf[112] : 03
rf[113] : 00
rf[114] : 01

SDK ver: 2.1.0(ace2d95) compiled @ Oct 24 2017 12:04:16
phy ver: 1134_0, pp ver: 10.2

I have IO0 in high state (also tried in float)
Everything was worked to moment when i sended to device:
"AT+UART_DEF=57600,8,1,0,3" so i turned on flow control.

Anybody have idea what is wrong?
What for is IO15? should it be in low or high state? (i tried both but program doesn't started).

The command you sent dropped the baud rate to 57600, so you will need to change the tty speed in order to see more output after that

There is not any more data. with tty on 57600 i see only garbage. Earlier, before changing baudrate (there was 115200) there was "ready" after garbage.
