ESP8266 - transfer some bytes PC<>PIC over wifi

[flotulopex]

Amgen,

Would you please share the firmware you've installed?

I tried so many that didn't work....

[flotulopex]

BTW, ESPRESSIF seem to have a firmware, the ESP-WROOM-02 Series that should fit the ESP8266 according.

https://docs.espressif.com/projects/..._binaries.html


It looks very easy to download the firmware to the module since one can choose between multiple .bin files (for the "experts" I presume) or a single .bin file (for th rookie I am )

The download process runs well with the ESP8266 FLASCH DOWNLOAD TOOL v3.9.5 but once the download is done, an error will always occur - must be some data copy check that doesn't accept the final result.

So, still stuck and searching....

If this comes through, here is the zipped 4 files to load and the screen shot for the locations they have to programmed to. I believe all this is still on Jeelabs git pages.
I'm sure you know that the program files need to be referenced in the folder you have put them.

one more edit for you...... if I remember?!@#...... had to check/box the 'DOUT' ... it was little tricky but once you get it it goes easy

Flash.zip

Thanks a lot Amgen, I'll give it a try tonight.

Until then, just a question about your addresses: are these really correct?



...or does it just doesn't make any change if they have one trailing zero less?

Okay, thanks to amgen, I finally successfully flashed my module.

But, still nothing works and sending AT+GMR will return...nothing at all.

Maybe my three modules are just defect...

I think I'm going to leave this by side for a while, go get a beer, and have some fun with something else and come back later

hey man,...... YOU DON'T USE AT STUFF........
What you do next is......1) power up 8266... (3 volts)
2) Look at your live WIFI network list for the ESP device and hook up your computer/laptop to that network, I put screen shot-
3) that opens the onboard web page for all the settings and type of access point (you can figure out) or I will share what I did
4) restart the device with your UART TX,RX connected to pic...... open say Hyperterminal connection type TC/IP winsoc
5) connect to your network ..... 192.X...... or 172.XX.......... port 23
6) once connected, you can send and receive at the baud you have set
....... suggestion, program PIC to serout some crap say once/second,...... then when you connect you can tell if shit is working
