Hi There,
Bought an Acrobat ESP8266 ESP-12e and been having issues getting up and running. Using Kali Linux with port ttyUSB0 set at 9600 baud.
1) Tried Adruino IDE with simple Blink program using recommended board settings but fails to upload code with following error - error: espcomm_open failed.
2) Then install ESPlorer but just times out when - Communication with MCU.............
3) Next installed Esptool.py to flash firmware. Again cannot connect to board when running the following:
python esptool.py --port /dev/ttyUSB0.SLAB_USBtoUART write_flash 0x00000 /home/xxxx/Desktop/v1111ATFirmware.bin
Error msg: serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttyUSB0.SLAB_USBtoUART: [Errno 2] No such file or directory: '/dev/ttyUSB0.SLAB_USBtoUART'
Verified the USB port with the terminal command:
XXXX@XXXX:/home/xxxx/Desktop/esptool# ls -la /dev | grep ttyUSB0
crw-rw---- 1 root dialout 188, 0 Aug 13 10:55 ttyUSB0
Sometimes when I plug in the ESP-12e board, the blue led lights up but most of the time it doesn't. Tried interchanging several USB cable but doesn't make a difference. Tried on Windows as well as other Ubuntu Linux box but same issue. Done lots of reading online and tried many different ways to troubleshoot but stuck.
Any suggestions on how to get the ESP-12e working would be greatly appreciated.
Thanks,
Steve
