Greetings,
i’m using the ec200-u cnaa module evb for a mqtt example provided for mqtt. When using the quecOpen example. Im experiencing data call error. When i flashed another firmware (EC200UCNAAR01A05M08). data connection works well on the Qnavigator application. The opencpu sdk version is (EC200UCNAAR02A02M08)
.After the flashing quecopen applciation_merge file I’m also unable to run set module apn activate internet via Qnavigator. I think the issue might be because of sdk version but anyways please help me out in getting to work the mqtt example. I have tried the ble example with the sdk and it works ok
