The locations are right.
I rechecked the uploaded firmware. Its working.
I believe, you are putting the ESP in run-mode (GPIO0 pull-up) after RESTting, and the serial baud rate is at 115200.

Anybody else are facing the same issue?

Edit:
However, I am adding fresh copy (V0.6) with little updated feature.
The AT+PINGROOT has been updated to AT+PINGROOT="............" . You can send data to Root node or co-ordinator. Data length is limited to 100 chars.

Thanks

Thank you for your response.

I tried with 0.6 and still nothing. I must be doing something wrong. I'm using NODEMCU Firmware programmer to flash. I connect CH_PD to 3.3v and GPIO0 to GND to flash. Afther flashing, I just disconnect GPIO0 from GND. No AP, nothing on serial, only when I connect RST to gnd I get the same string of garbage... 115200 baud on Arduino Monitor Serial with an CP2102.

EDIT: ok, now I'm getting serial output ( Scan starting...Data Scan Completed !!!! NO AP in MESH.Full Scan will be initiated), but it is not responding to AT commands(can't see the AP either). I flashed the v0.6, and then the files from the first bin.rar you uploaded:

eagle.app.v6.flash.bin --> 0x00000
eagle.app.v6.irom0text.bin -->0x40000

So it seems only with the bin's in "bin_0.6_03032015.rar" is not enough. Am I missing something here?

Again, thank you for your time.

Its interesting!
The eagle.app.v6.flash.bin and eagle.app.v6.irom0text.bin are required when the bootloaders are not required where as the other setup (user1, user2,..etc) are required when to use with bootloader.

Thanks, your exploration proved, there are many things still to know!
I shall look after the matter.
Please do test with multiple esp module. Place those little away (better to use USB extension cable if using same PC or laptop. Connect the opposite sides USB port at least) to avoid interference.

Thanks
