difference between protocols about esp-smartconfig-dart HOT 5 CLOSED

Use esp_smartconfig_set_type function, and set type to SC_TYPE_ESPTOUCH_V2. Then, before calling esp_smartconfig_start function, provide crypt key into smartconfig_start_config_t configuration struct.

Your code for setting SmartConfig to use EspTouchV2 with encryption key should look something like this:

...
esp_smartconfig_set_type(SC_TYPE_ESPTOUCH_V2);

smartconfig_start_config_t start_config = {
  .esp_touch_v2_enable_crypt = true,
  .esp_touch_v2_key = "SecretKeyHere123",
};

esp_smartconfig_start(&start_config);
...

Rest of the code should be the same as in your example.

Hi @mralperem

TL;DR: V2 is more secure than V1.

In V1, data is transmitted in plain mode, so if anyone in network intercept your data (ssid/password), he will be able to read it. In the other hand, EspTouch V2, uses key to encrypt data. When you initialize V2 protocol you need to provide key in format of string. ESP device needs to have the same key in order to decrypt received data.

thank you for your response. When i looked at your code i understand the difference but when i looked at the code for esp8266 provided from espressif system both protocol use the same code and there is no decrypt method. Could you provide a link for the esp8266 code you have used for esp touch v2. I might be looking at the wrong code.

thank you for the answer. I was able to find understand it. But do you know if does it support esp8266 or only esp32?

from esp-smartconfig-dart.

You'r welcome. It supports 8266 as well. Here is SmartConfig docs for 8266 RTOS SDK.
