Hello Community,
I am totally new to this community. I am facing a issue which may be really common issue.
I flashed my Heltec Esp32 Automation kit with "espruino_esp32.bin" Upon flasing I saw below console message.

esptool.py v3.2
Serial port /dev/ttyUSB0
Connecting....
Chip is ESP32-D0WDQ6 (revision 1)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
MAC: 3c:71:bf:ff:11:f0

Hard resetting via RTS pin...```

Which according to documents looks normal.
But then when I tried to connect the board with 
"espruino" command I am getting the following error same error I am getting while connecting to web IDE  below is the error.

Using first port, {"path":"/dev/ttyUSB0","usb":[10,null],"description":"Silicon Labs"}
Connecting to '/dev/ttyUSB0'
No result found for "process.env" - just got ""
Unable to retrieve board information.
Connection Error?
Connected```

I am using Heltec Automation WiFi Kit 32 V2 and attached is the bin file I used

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
