Hi Guys, I’m new to this and its doing my head in!
I have a doit.com ESP13 WiFi Shield - I can connect it to my home WiFi, I can send and receive data via the Serial Monitor so I knw the sheil is working, however I can NOT get it to work with any of the Blynk sketches!
I have setup the app, i have my token, I followed the instructions but no joy.
This successfully connects to my home WiFi, I can send and receive serial data to the remote IP and see the data with TCP Console and Serial Monitor. I can switch a LED on/off with this remote setup.
When I then run BlynkBlink sketch it uploads OK but the serial monitor displays
“[0] Blynk 0.4.0 on Arduino Uno”
“[0] Getting IP…”
When I run LED_Blink I get the same result
After a minute or so it returns [130466] DHCP Failed!
Hi Mate, thnx. Good timing, I’ve been doing that just now.
ESP8266_Shield
I // out the lines for Mega etc
I include the lines for software SER for UNO, the sketch compiles and uploads OK
SER Monitor shows . . .
[[19] Blynk v0.4.0 on Arduino Uno
[520] Connecting to GoTigers!
[1536] Failed to disable Echo
If I manually configure the shield I can connect to WiFi, port forward, send/rx data etc.
When I reset the shield then try to connect with the sketch it does not work.
It appears the sketch is not uploading the data to the shield?
No, you’re wrong here. It shows basically the schematic of your shield. You don’t need to wire like that - your shield does it for you. You just need to take correct pins and baud, and update them in Blynk example.
The link is ALL about shields it’s just that there are different versions of shield. The diagram is a shield. The USB-UART TTL is needed for many shield users but not yours.
Study the AT commands in the link, check which firmware you have etc.
