Connecting to Bittle through WiFi?

How to connect Bittle x to wifi.

Thanks.

thanks, I will test it

@Rongzhong Li I can control Bittle from Webclient through WIFI at my IP address 192.168.88.33 using the control panel. How can I run a script in python run in Ubuntu/Windows through WIFI, for example example.py one that you provide in ardSerial package ? I can run it through RPi wire-connected through serial (RPi-NYBoard), but I cannot figure out how to run the same without RPi and with WIFI adapter plugged into NYBoard. Also I would like to test WIFI from RPi instead of using Ubuntu/Windows.

@Rongzhong Li WIFI adapter works after replacement. Thanks for the quick assistance.

@Rongzhong Li thanks, I just sent out my address in Shenzhen .

@Rongzhong Li is there any retailer in China ? Shipping fees and time make it difficult to justify delivery from US. Alternatively I temporarily stop working on wi-fi and develop python script on RPi for the forthcoming fair.

@Rongzhong Li thanks for the quick reply. In fact I paid attention to it and I connected trying both possibilities TX - RX , shifting the pin connecting positing of the wiring to avoid any mismatch. Any other possibility ? Can it be a WiFi board issue ?

@John Winiger thanks for the input: I was missing this point. In fact I am using a FTDI232 instead of programmer which was defect as already verified. FTDI232 works fine when uploading to NYBoard.

After testing I still receive the following error when uploading to WIFI Adapter. I checked pins connection TX to RX and RX to TX but it gives error. I attach also the picture of FTDI-WIFI connection. Any hint ?

Just saw this picture and can right off say, it doesn't work like that, trust me I tried. Unplug the programmer from Bittle, so you just have USB to programmer and wifi plugged into programmer, then select the wifi adapter as the board you want to program and it should work. After the wifi adapter is programmed just plug it straight into Bittle and it should work.

Your picture shows you are connecting the USB uploader, the keyboard, and the wifi all at one time. It should not be that. Only combine two at one time. Otherwise, there will be three guys taking over the single channel.

You don't need to switch the I2C to RPi. It's only used if you write a completely new firmware on the RPi to over all the I2C peripherals on the NyBoard.

@Rongzhong Li validating the Pi's functionality by jumping wires between the serial ports: Tx to Rx and Rx to Tx. As for follwing picture:

I have following result:

On top of cli Petoi is powered (battery is ON) and the script raises error. On the bottom battery is OFF and the script confirms connection serial port is well. What is the problem ? NYboard is programmed with opencat.ino and I2C switched to RPi.

WIFI adapter issue, hereafter the boards connection to flash the program into WIFI adapter module. I think the issue is the USB loader already verified to be defect. I look forward to your comments.

May I see the picture of how you are connecting the WiFi module? When programming it, you need to remove the uploader from the NyBoard.

The WiFi, Bluetooth, and USB uploader all work with the only serial port of NyBoard V1. The commands are sent to the serial port as string tokens. You can validate the Pi's functionality by jumping wires between the serial ports: Tx to Rx and Rx to Tx.

@Rongzhong Li I could compile successfully ESP8266WiFiController.ino However I cannot understand how to flash it (or upload it) into the WIFI Adapter of Petoi kit. I tried to do it using the uploader and connecting it to the PC, but I receive an error as for following picture.

My intention is following.

Avoid soldering the RPi board on top of NyBoard before I can confirm that all basic control through RPi works. Using SSH on RPi and having WIFI adapted I can test functions before soldering RPi on NyBoard. For this purpose I let RPi control Bittle postures based on RPi camera feed-back signals. pyBittle library will be used accordingly.

I just checked out at https://docs.petoi.com/modules/wifi-esp8266: I found out that not having the original UBS loader (you may remember it was defect and I bought a FTDI module) the FTDI module has not female plug to insert the WIFI. From here the question how can I flash my WIFI Adapter. Question: is there any re-seller in China to indicate to buy the UBS loader ? Or have you got any other module for equivalent function ? Thanks

So WiFi control using the included sketch is working for me. On a quick test, the only issue I had was the instruction would go but the page wouldnt always come up on my phone (like the page still reloading). So i could reload http://192.168.1.#/action?name=hello and get the wave, but the buttons wouldn't come up. Still pretty good for out the box - thanks

Hello, I have been testing the wifi module and suddently, when I send the command FORWARD, Bittle won't listen to any other command and won't do anything. It also happens with BALANCE (I can make Bittle sit and say Hello, but if I send BALANCE command, the gyroscope will be disabled and won't listen to any other command.

Has this happened to anyone else? @Rongzhong Li do you know what might cause this behaviour?

All I have done was sending commands through the API and eventually Bittle isn't listening to commands once I send to go forward or to balance

Connection issue resolved

ESP8266 would not connect to ASUS router.

Go into 2.4ghz setting and change "Wireless mode" to legacy and it connects.

Now that it's all up and connected the next step is how to access it from a browser. Just entering the IP address does not work. Has anyone gotten this to work and are there any tricks?

Mac FIX!

I did a lot of searching and found there is a problem with the package.

I used these commands and I also installed the Mac serial driver and now it works!

cd ~/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1

sudo unlink python3

sudo ln -s /usr/bin/python3 /usr/local/bin/python3

sudo ln -s /usr/local/bin/python3 python3

Getting closer...

I want to add that I seem to have found a sweet spot! Watching the serial monitor I could see it would try to join my network and fail. After that it would revert back to the Bittle-AP, at that point I go to my wifi and join it and then open a new web browser page. This brought me back to the wifi manager page! And on the bottom of one of the pages it listed extra command you can use on the end of the URL.

OK, I have made some progress int he Win10 environment. I had the wifi module plugged into the programmer, and the programmer plugged into Bittle, wrong!

With just the wifi module plugged into the programmer I was able to get things to work a little more!

It seems that if you see ESP-XXXXX in your wifi network list it means the module has not been programmed. After I was able to upload to the module the ESP_XXXXX network was gone and Bittle-AP now appeared! I joined it and then the Wifi management page popped up in my browser. I entered my network name and password and saved it. I have seen times when it does connect to my network but have not figured out how to connect to it.

Also, about it shows the home and action pages, I cannot figure out how to get to those. With the serial monitor open it gives some interesting information and gets to a point where an except happens and it seems to reboot itself.

It might be helpful if I can find a way to reset the module.

Let me know if this is helpful and if anyone has any further idea!

So I setup the Arduino environment on Windows 10 in a VM and tried everything again. I got the exact same errors as shown by @Struzck above.

So any ideas on this would be great and I am going to look into ESP8266 not running the same on the Mac.

I saw that you made an update to ESP8266WiFiController.ino I downloaded and tried it. The verification works without any problem now, but when I try to upload it I get:

pyserial or esptool directories not found next to this upload.py tool.

Might be something you are already aware of but just in case not I thought I would let you know...

I did that and if I try anything with ESP8266WIFIController I get:

Arduino/libraries/WiFiManager-master/strings_en.h:384:7: error: 'wifi_country_t' does not name a type const wifi_country_t WM_COUNTRY_US{"US",1,11,WIFI_COUNTRY_POLICY_AUTO};

Arduino/libraries/WiFiManager-master/strings_en.h:385:7: error: 'wifi_country_t' does not name a type const wifi_country_t WM_COUNTRY_CN{"CN",1,13,WIFI_COUNTRY_POLICY_AUTO};

Arduino/libraries/WiFiManager-master/strings_en.h:386:7: error: 'wifi_country_t' does not name a type const wifi_country_t WM_COUNTRY_JP{"JP",1,14,WIFI_COUNTRY_POLICY_AUTO};

If I go back and switch the board back to the Arduino Uno and try to upload ESP8266WIFIController it says it can't find:

ESP8266WiFi.h

DNSServer.h

ESP8266WebServer.h

I do not have the new M1 chip, just the older Intel.

ESP8266 Community is what I had already installed when I searched for ESP8266...

OK, I'm stuck on this as well..

To start I am on a Mac..

I added the url in Preferences

Added ESP8266 in Boards Manager

Downloaded and installed WifiManager - I did not remove the -master

Under tools - board - ESP8266Boards I do not know if I am supposed to select a board here and if so which one, there is no ESP-WROOM.

Any ideas?

Yes, please check this code. Brief instruction is provided at the beginning of the code.

Any updates so far?

The WiFi module is used for programming, not the simple transparent transport bridge through the WiFi and the Serial.

The English version of the tutorial for the WiFi module is under construction, it will be finished in a few days.
