Building a WiFi Gateway with ESP-01

[DrKuebel]

Hi all,

I´m trying to build a WiFi Gateway using a ESP-1 with 8 Pins.
Unfortunately I did not manage to wire it up like discribed here:
http://www.mysensors.org/build/esp8266_gateway

The mentioned pins are not named the same way..

• nRF24L01+ ESP8266
• VCC VCC
• CE GPIO4
• CSN/CS GPIO15
• SCK GPIO14
• MISO GPIO12
• MOSI GPIO13
• GND GND

On the ESP-1 the Pins are named:

VCC
GND
TXD
RXD
CH_PD
GPIO0
GPIO2
RST Reset

Could anybody give me a hint?

Thanks

I've been using this image:

from http://smarpl.com/content/esp8266-esp-201-module-first-impressions to map IO ports. Even printed it on paper to make it easy to reference. Maybe ESP-1 is similar enough?

Edit: No, it looks like ESP-01 exposes too few pins to be usable? At least according to http://www.electrodragon.com/w/Category:ESP8266_Basic_Usage

@DrKuebel ESP-01 has not enough general purpose data pins. Besides Vcc and GND you need 5 GPIOs. ESP-01 only has 4.

Thanks...
so I will buy me a new one... wich ESP-?? would you recommend?

Most people probably use the NodeMCU since it is recommended on the build page: http://www.mysensors.org/build/esp8266_gateway

A nice comparison is available at http://blog.squix.ch/2015/03/esp8266-module-comparison-esp-01-esp-05.html (scroll to the bottom for a comparison table)

Depends on. An ESP-12 would be minimalistic. An ESP-201 can be used in breadboards. A node-MCU is a complete development board including the programming interface. But there are a lot of others.

Thanks for the fast help... I´ll try the NodeMCU
