我第一次尝试了使用arduino nano 33iot和经典arduino ide的示例echobot。我使用botfather创建了一个机器人。我已经把例子的代码上传到了板子上。串行监视器告诉我它已连接到wifi，并显示了SSID, IP地址和信号强度，但当我试图使用电报机器人写一些东西时，什么也没有发生:我在机器人聊天中没有收到回声消息。有人能帮帮我吗?
这是代码:
/*******************************************************************
A telegram bot for your WifiNINA devices that responds
with whatever message you send it.

您需要将Telegram根证书添加到Wifi模块。使用Wifi101/WifiNINA固件更新程序.
