Hi,
I am a new user of the ESP-01.
I constantly getting an error while uploading a sketch or even trying to communicate with it.
When I try uploading the sketch I get this:
"Sketch uses 246,319 bytes (49%) of program storage space. Maximum is 499,696 bytes.
Global variables use 32,276 bytes (39%) of dynamic memory, leaving 49,644 bytes for local variables. Maximum is 81,920 bytes.
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed"
When I try serial communication I get all kinds of letters and signs (like when it is not the right baud rate) for 115200 baud with both NL and CR.
With the 74880 baud rate I get:
"ets Jan 8 2013,rst cause:1, boot mode:(3,0)
load 0x40100000, len 612, room 16

€€€€€€€€€€€€"
With the 9600 baud rate I get:
"0 ]ŠÌ
ÿa��+çh„á V=ü��™j!šA��3 „DaÀ�A†<@ÃH,Ιºþ
ready
"
I have no idea why i keep getting this. The AT commands don't seem to do anything.
The red LED is on and the blue LED blinks after resetting.
I am connected to an arduino UNO which is not in reset mode (the is no wire between gnd and rst) and I have no idea what kind of esp 8266 -01 I have.
please help!
Thank you
