Working with ESP8266 (ESP-07S)
Working with ESP8266 (ESP-07S)
I have noticed this version of the ESP8266 features an IPEX connector for an antenna. I was wondering if it differs in any other ways from other chips and if there are any issues with it or anything else I should know?
Re: Working with ESP8266 (ESP-07S)
Should be the same ESP8266EX chip in all of the ESP-xxx modules.
Some are configured with more flash memory.
Some expose additional pins.
Some have a metal can / shielding.
See http://esp8266.net/ for more specifics.
IPEX / U.FL connectors are only rated for a small number of reconnects. Maybe 20-30x reconnections. That's the main concern.
They are also 50 ohms impedance, as with bigger (RP-)SMA connectors.
Short U.FL -> SMA pigtails are fairly common and cheap.

Re: Working with ESP8266 (ESP-07S)
Hi Sir,
Receltly, I also got my ESP07S. originally, I used ESP8266-12E with arduino IDE (Node MCU 1.0-12E setting) to do code, burn and test. Everything was fine. Thing wend weird when I switched to ESP07S. I also use arduino with Node 1.0-12E setting to do code and burn, it can be burned without any error. I also follow ESP07S user manual GPIO and write a LED blink via GOIP, it cames out with error and board keep resetting. I check my code. It is really easy without any extra code below.
burn this code and ESP07S keep resetting !!
Did I do anything wrong ? Or I need to do some parameter change for NodeMCU 1.0-12E setup ?
Can you help me with this ??

Code: Select all
void setup()
{
pinMode(10, OUTPUT); // GPIO-15 ( according to ESP07S user manual, page 6 )
// https://www.rfsolutions.co.uk/downloads/1494602250ESP-07S_Datasheet.pdf
}
void loop()
{
delay(1000);
digitalWrite(10, HIGH);
delay(1000);
digitalWrite(10, LOW);
}

Re: Working with ESP8266 (ESP-07S)
This is the Micropython forum. Your code is C.
But your problem is that you should use the GPIOxx names as pin and not the physical pins of the board.
