Unable to get Wifi interface working (Olimex-MOD-WIFI-ESP8266)

[okashira]

Hi all.
I have a tesla Small DU board Ive soldered up myself and im trying to get the Olimix board working.
Ive flashed the STM32 just fine with ST-LINK, that is not a problem so far.

To flash the the Olimex board (ive tried 4 of them) I follow this process:
Solder GPIO 0 to the "flash setting)

1. Connect the Olimex using an FTDI USB to TTL adaptor. COM2 115200 baud. This connects fine in Arduino. 3.3V power.

2. I setup arduino IDE 1.8.0 with https://github.com/esp8266/arduino-esp8266fs-plugin and https://arduino.esp8266.com/stable/pack ... index.json

3. I setup the arduino sketch directory with the "FSBrowser directory, and make a data directory inside and copy the relevant files:
(the arduino sketch directory also has the tools folder for the file system thing)


4. Install ESP8266 library needed in Arduino

5. Select Olimex board in Arduino with these settings:


6. Build and flash FSBrowser

7. Wait 10 seconds then depower Olimex board, wait 10 seconds and repower

8. Run Tools---> ESP8266 Sketch Data Upload.

***both flashing go perfectly according to the logs.***

9. depower and solder GPIO0 back to default

10. Plug into The Tesla SMALL DU board and search for Wifi.

A wifi network of ESP-03F7F4 appears with no password. I am able to connect. But nothing is there.
----The network name is not "Inverter" like everyone says it should be
----There is no password on the network
----192.168.1.4 does not exist.

here are the network i get when I connect:




has anyone been able to flash Heubners web interface to an Olimex board before and get it working? what am I doing wrong?

Maybe this will help you, specifically #10:

----The network name is not "Inverter" like everyone says it should be
----There is no password on the network
----192.168.1.4 does not exist.

Well done on the flashing but some misconceptions:
- The network name is not statically defined in code but saved in a special flash area. It defaults to what you state
- Password: same
- It's http://192.168.4.1

Thank you for the reply. Sorry for the typo. 192.168.4.1 was also unreachable.
I was able to get a connection. I had to force some TCP-IP settings as follows:


It's unfortunate because it means I have to change tcp settings over and over if I switch between internet and the ESP. I don't know how to connect on cell phone.
The other web interfaces do allow for 192.168.4.1 with autoconfig DHCP (i flashed These two and they "worked" (except I had lots of parameter issues))

Is there a way to get DHCP to work properly?

Thank you!

gateway shouldn't be filled with the device IP adress if you do that the device will be forwarded with all network traffic not being for your subnet (that in essence is what a gateway provides. Acces to IP's out of your subnet.

So leave it empty or fill in another number i would say. If the subnet and the IP adress are within the same range communication is already possible.
Leave the gateway configured only on your internet interface.

You can configure the interface for 2 static IP addresses - check advanced button- one which you already received from the DHCP server and one with a subnet for this WiFi module. I assume that you are on a laptop.
