| Dec 1, 2020 at 16:31 | comment | added | Peter Paul Kiefer | To which voltage 3.3V or 5V do you pull up the SCL and SDA line? Is the MCU a 3.3V controller? Just connecting D1-SDA D2-SCL is not enough. If the electrical setup is OK, you could remove all the Wifi and JSON code from the MCU prog and try I2S alone. Another strange thing: you call client.begin("http://..."); each time you call the getCode() method without client.end(). Perhaps this crashes the connection to the server. I don't know if the client.begin is safely callable twice without calling close before.. | |
