My nodemcu is stopped working properly. i don't know weather this is a hardware problem or something else.
I am able to flash the frimware (nodemcu and espeasy) but i am unable to load any code into it.
errors are as following
1.while using arduino ide-
when press upload sketch then i got
failed sending 1070 bytes
failed sending 1040 bytes
.
.
espcomm_send_command: didn't receive command response
espcomm_send_command: (Flash_download_data) failed
espcomm_send_command: wrong direction /command: 0x01 0x03,expected 0x01 0x04
espcomm_upload_mem_ failed.

after these errors nodemcu stops doing everything (previously it was showing as wifiap)

2. I tried Esplorer lua programming
but after loading any code the board gets unresponsive and shows:
can't auto detect frimware
waiting answers from esp- timed out


When i flash it with nodemcu flasher it starts and also accepts serial communication but after uploading anything into it, it behaves like fainted away.

I'm not sure what's going on to be honest. Are you using the latest NodeMCU firmware (maybe a build from nodemcu-build.com)? Are you connected with 115'200 baud? "can't auto detect firmware" from ESPlorer doesn't mean much, you can safely ignore that.
