Im getting this error and cant figure out what is it, Im trying to use nodemcu esp8266 (12-E) board :

i got the same error when using arduino ide. i ended up using the flash_download_tools to upload a bin file

[Josepaezra]

And how could i get the binaries to upload to flash download tools, if i cant compile it (from the Arduino ide)? I´m sorry and thanks.

[coldfire0101]

firmware.ino.nodemcu.bin theres 2 binaries in that folder

[Josepaezra]

At what directions did you saved this files? Which ones you used?

[coldfire0101]

https://szsmart.readthedocs.io/en/latest/zhRobotArm/HumanoidRobot/ViViRobot/ViViUseInstructions.html#

scroll down to 2.2.8.5.3. 3. you will have to use translator as it is mostly in chinese

[coldfire0101]

did you have any luck

[coldfire0101]

ok so far i think from what i cant tell firmware.ino creates a mesh network allows calibration but doesnt contain any motion files, firmware-7-3 contains everything but it isnt creating a wifi ap at least on my board

[Josepaezra]

Hello Sorry for not answering back at the moment. I m printing the robot chasis now, im halfway through, Im continuing now. There is ways to upload the motions to the board. You could google translate this whole document in chinese to english: https://github.com/Nicholas3388/ViVi-Robot/blob/master/%E5%8A%A8%E4%BD%9C%E6%96%87%E4%BB%B6%E7%83%A7%E5%86%99%EF%BC%88%E6%A0%BC%E5%BC%8F%EF%BC%89.pdf
In where is shown a method.
There is also a software that seems to be for this purpose in here: https://github.com/Nicholas3388/ViVi-Robot/tree/master/%E5%8A%A8%E4%BD%9C%E6%96%87%E4%BB%B6%E8%B5%84%E6%96%99

I uploaded firmware.ino and a led next to the wifi antenna starts blinking, but i cant see the device board reflected on the wifi panel of my phone.
I downloaded a serial port assistant but i havent verify the status of the board in it, I set the parameters: Configure the baud rate, data bits, parity, stopbit; receive and send setting in ascii, and then send the message "$pm26" but got no message back.

I have a question, what is the purpose of the bluetooth module? Because i dont have one, coulnt i connect to my phone through the wifi antenna?

[coldfire0101]

when it is running it should start wifi ap you connect to with 123456789 for password, when that is done go to the control app and use search button and it will connect(should connect)

[Josepaezra]

Ok, i´ll keep trying. Now, if you disconnect the bluetooth module are you able to connect via wifi and do the normal calibrations? I m asking because i dont know the purpose of it.
Also, did you manage to upload the motions through the motioninstaller.exe app? Using firmware.ino as you mention.

[coldfire0101]

i dont have a bluetooth module, only have wifi. i had no luck with the motioninstaller

[coldfire0101]

1 step forward 2 backwards. just found you can flash firmware.ino.nodemcu over the top of ViViRobot_7_3 firmware which stops the robot crashing when trying to do a movement but i calibration does not work properly so back to square one.
what pcb are you using, mine does not have anywhere for Bluetooth

[Josepaezra]

I havent figure out how to flash it correctly yet so i can connect via wifi. Im using an nodemcu esp8266 v2 (with ESP-12E), with a pca9685, i looked at the circuit diagram and figure i could use them. Which one are you using? I m also using mg90s servos, i found a 3d model for them.
We have to keep pushing until we manage to make it work, salute.

[coldfire0101]

im using the official 8266
