在使用此方法之前,需要将服务器使用的 SSL 证书加载到 Arduino WiFi Shield 101 中。Shield 已经加载了证书,应该可以使用了。要更改或上传新的 SSL 证书,您应该遵循将提供的程序。 connectSSL() 还支持在使用域名(例如:google.com)时进行 DNS 查找。 用法 client.connectSSL(ip, port) client.connectSSL(URL, ...
The Arduino download worked but it is version 2.1.1 while this project (from Dr. Duino website) requires version 1.8.19 for his Mini Weather Station project. The newer version doesn't work on this thing. It's odd that I did download version 1.8.19 once and I still have it open - d...
3. The library which is going to be used to send handle the data with Ubidots uses the digital PIN "JP" of the SIM900 (PIN 9 in the Arduino) to power on/off the GPRS shield. Make sure the JP pad is soldered. The pad of the JP pin can be found next to the ISP port o...
