Thanks for you answer.So I prefer to use deep switches. If I well understand the next step is to have AT commands response but I don't. What may I precisely have to do? Do I need to reflash the ESP? What are next steps?
I don't understand, they said to upload a sketch at the bottom of this page:https://robotdyn.com/uno-wifi-r3-atmega328p-esp8266-32mb-flash-usb-ttl-ch340g-micro-usb.htmlWhat I did. AT commands are not responding and the led of ESP is well blinking.load 0x4010f000, len 1384, room 16 tail 8chksum 0x2dcsum 0x2dvbb28d4a3~ldAT+CIPMUX=1AT+CIPSERVER=1,5000AT+CIPSTO=3600Are AT commands so importants for esp to Arduino communication or I can manage it by another way? if Yes, how can I do?
HiI am a "newbie" and I am stuck. I just purchased the Robodyn R3 Uno wifi. I can find sketches to put on the ESP8266 to connect to the internet and send numbers to Favoriot web page. I can load scripts onto the ATMega328 to read a DHT11 temperature and humidity sensor. I want to read sensors attached to the pins and then send out the data to the internet (e.g. favoriot or php page). I found a tutorial that loaded a sketch onto the ESP8266 that suppose to read a DHT11 and then send it out to favoriot, it did send numbers out out to favoriot, but it was unable to read the DHT11 sensor, it just read "0" (https://github.com/LintangWisesa/RobotDyn_UnoWiFi_Favoriot). I did set the dip switches to 1-2 On 3-7 Off to connect the ESP8266 to the ATmega328.I understand you were able to communicate between the ATmega328 and the ESP8266. I read there are two ways(a) connect the RX and TX pins of the ATmega328 and the ESP8266 with jumper leads. 1) I thought drop down resistors/module must be used between TX of ATmega328 to RX of ESP8266 to drop voltage from 5 to 3 v, is this correct? 2) If I do what is in (1) I guess I can send AT commands to control the Wifi? 3) If I do what is in (1) does any one know of sketches that can read a sensor from the ATmegae 238 (e.g. DHT11) and then send the readout it to the ESP to eventually do a POST to a php page or favoriot?(b) use code to communicate bewteen the ATmega328 and the ESP8266 (1) is see in the code provided was able to send some data to the ESP8266, but then how to you then make is do a POST with this code?Thank you
B) EXTERNAL RX TX WIRED CONNECTIONConnecting RX and TX pins of the ATmega328 and the ESP8266 with jumper leads. I also used a voltage divider when connecting the Tx pin of the AT328 to the Rx pin of the ESP because the ESP reads 3.3v and the Tx of the ATmega328 sends out a 5v signal, so best to reduce its voltage. I tested the divider and I read 3.16v.
