Hi all,
I created an account recently as I desperately need to get my ESP8266 WiFi module working. I've looked around a lot and have been trying on and off for a week or so now, and I can't quite get anywhere with it. So far, I've tried a number of things, including;
- Downloading ESP8266 from the board manager
- Connecting IO0 to GND when flashing
- Checking RX and TX are wired correctly
- Using flashing software to test connection (the connection itself seems to be where the problem lies)
- Using AT commands (no response)
- Using different ESP modules (I've bought two sets from different sellers, with zero luck)
I'm still trying to work out what the problem could be. Further, the pins on the module read as usual besides two; EN (I've heard this is in place of CH_PD and means the same thing), and 3v3 (I'm guessing this is just VCC). I don't think this changes anything but I thought it might be worth bringing up anyway. The code I'm using when trying the AT commands is just the blank sketch which looks like;
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
I'm not sure what could be causing the problem. I feel like it's all wired correctly (I've followed the tutorials online), and I don't know what else to suggest that could be the problem. I'm especially lost on this one (and it doesn't help that I'm not particularly good with hardware stuff / Arduino in the first place).
Just some other things to note beforehand;
- I'm fairly certain the issue isn't the COM port (this works fine with other sketches)
- The MEGA itself seems to be in fine shape
- I bought the hardware recently and so assume it's not a problem with that (though it's a possibility that it was defective, I don't see the likelihood of this occurring twice from completely different sellers)
- My breadboard is quite busy. I don't know if this changes anything though
The only alternative if I can't get this to work is to find another WiFi / networking solution altogether, which is my last resort. Also, please let me know if there are any more details that are required.
Thanks,
S.
