I have a small question.

[codingwithmeow]

Hello,

So I want to send an email using Raspberry Pi Pico W I tried your examples and it did not work. You are saying it can be used in RP2040 can you explain how?

Thank you in advance

Hi, here my example ` /*

• EMailSender library for Arduino, esp8266 and esp32
• esp8266 Gmail send example with 2 attach loaded in LittleFS
• You must change on library file EMailSenderKey.h this line

• define DEFAULT_INTERNAL_ESP8266_STORAGE STORAGE_SPIFFS

• in

• define DEFAULT_INTERNAL_ESP8266_STORAGE STORAGE_LITTLEFS

• The base64 encoding of the image is slow, so be patient
