I purchased this module from dx.com
http://www.dx.com/p/esp-07-esp8266-seri ... QYFPFV95hE
There is little to no support for how to get this thing working.
I have it wired up to an Uno board, VCC to 5v, GND to GND, Tx to Rx and Rx to Tx on Arduino
Although I have tried mixing up Tx to Tx and Rx to Rx as well.
Have tried to flash, send AT commands, various things, none of which seem to be working.
I can see an AP called "ESP_03890B" when it is in UART mode, which I can connect to and get an IP address, so I assume DHCP must be working on it (192.168.4.2), but if I try to connect to 192.168.4.1 via browser, it finds no site.
I do not have a USB to UART cable, and there is unfortunately no micro USB on the board to connect directly.
I cannot flash the firmware, I cannot upload sketches, all I have had is occasionally:
- Tx blinking on arduino (in UART mode)
- Rx blinking on arduino (in UART mode)
- these obviously change when I swop the TX and RX wires - It's coming from Tx on the 8266 unit
- Gibberish in the serial monitor when changing baud rates or resetting unit (at 300, 9600, 19200, 38400, 57600, at 74800 I get THIS:
ets Jan 8 2013,rst cause:2, boot mode:(3,6)
load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d
v09f0c112
~ld
Nothing at any speed higher than that
I am really lost....
