thanks problem solved

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.

Thanks, but from screen shot you can see that the serial port is ttyS0 (though the last digit 0 is cut off from the picture)

@Rongzhong Li please advise if you have met this issue as for previous message screenshot. Furthermore I found out that by replacing the USB cable the WIFI adapter and USB loader (programmer) operate properly. I apologize for bothering. Finally while testing WIFI adapter I realized that the IP address indicated in the manual https://docs.petoi.com/modules/wifi-esp8266 192.168.4.1 did not work. I connected the serial port of USB loader by cable to the Ubuntu *with WIFI adapter connected to USB loader as for instructions) and opened the Arduino IDE serial port and read the correct address 192.168.88.33 In this way the control panel commands on mobile phone work smoothy.

Test result: the full cycle is executed by Bittle with Battery ON. Response is still empty or with incorrect characters, as for below picture

@Struzck @Rongzhong Li I found the problem: Serial master folder was not located in the correct location, that is not into pyBittle-Master folder. Now it works, but there is still a problem as you can see from following screenshot, after running python3 exampley.py The top part is run with RPi powered and Bittle connected but with battery OFF. The bottom part is with battery ON. Whereas with battery OFF the full script is executed, when Bittle actually moves and carry out the instruction, it stops after the 7. step. Additionally on top you can see the 'Response' in full, whereas on the bottom 'Response' is empty. Any hint ?

@Struzck @Rongzhong Li I followed pyBittle installation instruction on RPi (Buster OS) as for https://enriquemoran95.gitbook.io/pybittle/user-guide/installation, However when running last command 'pip install . ' I receive following error: AttributeError: 'PosixPath' object has no attribute 'read_text'. Is there anything I am missing ?

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

I purchased the MU Sensor and I checked instructions at https://morpx-docs.readthedocs.io/en/latest/MUVS3/MUVS3_Arduino/MUVS3_Arduino_Guide.html#connect-to-arduino. Yet I think I will need to connect the MU sensor to RPi and through the serial port instruct Arduino for Brittle movement. If it is the case what are the MU sensor setting ? Additionally I read in another post to check in github petoi/trackball to test it. However I cannot find the file in opencat github. I appreciate if you can indicate a link to related instructions, possibly also to software with implemented examples. Finally I read from above comment that MU module for Bittle was order made: is my understanding correct ? thanks

@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 ?

@Rongzhong Li I just tried using FTDI232 (programmer module is defect). The result is as for reply to @John Winger below

@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 ?

WIFI Adapter module issue: I need to flash the ESP8266WiFiController.ino into the WIFI Adapter module. How can upload it without USB loader from the Ubuntu desktop (I think you refer to it when you write keyboard) ? Please expand, thanks

Thanks it works now. Yet I need to add MU Vision sensor, gesture recognition module and possibly speak recognition. Is the switch still to be set on Arduino ?

@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.

@DJ S your project looks impressive. Could you please share it as you intended ? I believe it will be useful for many in the forum. Thanks!

@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
