Esp32-wrover-e default software

[stokersoft]

Hi,

We are using the Wroom-02 module and its very reliable and effective. It comes with AT command software preinstalled, and we control it via the uart from our devices.

Now we need to extend with Bluetooth and Ethernet, and are looking at the ESP32-Wrover-e.

We bought a sample but it seems like there is no software. What should we expect for default software, we were expecting we could just control it with AT commands out of the box, but this is what we see, over and over, when we attach a USB-ttl adapter:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff
invalid header: 0xffffffff

Are we wrong when we believe it can just accept AT commands like the Wroom-02 module out of the box? Or is this normal? We purchased a new Wrover device, but same result.

On my ESP32-WROOM-32E the same effect.
Before that I had ESP32-WROOM-32D and it was working fine.
In both cases I use olimex ESP32-Gateway demo board.
Anyone has any idea?
