how to get custom data from phone to esp32 via ESPTouch V2

[vominhmanh]

on the app ESP Touch on tab ESPTouch V2, I see an input for custom data , but on ESP32, I don't find out any function to get it.
Can you show me function to get it, thanks.

Hi you can try something like this
uint8_t rvd_data[33] = { 0 }; if (info.sc_got_ssid_pswd.type == SC_TYPE_ESPTOUCH_V2) { ESP_ERROR_CHECK( esp_smartconfig_get_rvd_data(rvd_data, sizeof(rvd_data)) ); }
then you can use rvd_data elsewhere

@edg2411 why rvd_data[33] ? As I see the app can send upto 64 charcters. Is the 33 or 64 a soft limit or a hard limit?

Hi I have honestly no idea of the internals.
