WiFi (esp8266) robot

#1

Hi!

Has anyone tried to connect a typical ESP8266 module in the bluetooth socket of makeblock? I suppose that properly supplying the ESP8266 module you can use the same Tx and Rx pins of bluetooth makeblock socket, right?

Here is a link where shows the circuit schematic of Makeblock Me Wifi module. You may check if the info helps to your application.

Thanks, but I was wondering if it’s possible to connect a third-party ESP8266 (http://benlo.com/esp8266/ESP8266-ESP01.jpg) in the makeblock Bluetooth socket (not in sensor sockets), just manually wiring TX, RX, Vcc and GND connections of ESP8266.

(I edit: I’m using the basic mbot)

Thanks!

I saw online that the Bluetooth socket of mcore is directly connected to serial communication, so would it be possible doing a connection like this?

Thanks!

For this kind personal DIY application, we may don’t have enough ability to support.
Maybe some one who has similar project can share it.

Finally I went ahead and tried to connect a third party ESP8266 directly to RX/TX pins in the board…

Now I have an IoT controlled robot :robot:!

I have similar project to work with… have you been able to send command from esp8266 to mcore and vice versa?

#8

Yes, the RX/TX pins are directly connected to mcore, so you can connect a serial device and communicate them.

In mcore you must use: SoftwareSerial mySerial(0, 1); // RX, TX

You must disconnect serial devices when uploading code!

Javi, did you you the wiring as in the diagram above?

#10

Yes, in my case I used a Wemos D1 mini. So I just connected:
Wemos Rx --> mcore Tx
Wemos Tx --> mcore Rx
Wemos 5V --> mcore 5V
Wemos GND --> mcore GND

#11

Thank you… i will try it hopefully it works

#12

I tried to code the program using arduino ide but mcore doesn’t accept programs from arduino ide, I have to program it from mblock but there’s limitation I can’t include some functions such as SoftwareSerial x(0,1) …, how did you upload it??

#13

What version of Arduino IDE are you using? mcore is detected as Arduino UNO, so you select corresponding usb port and upload code

#14

i’m using 1.6.12 but there’s no option for arduino uno board

#15

I have both Arduino IDE 1.6 and 1.8 and I have the option of Arduino UNO, check in tools, boards

can you share your sample sb2 or ino file?
