Hi shramik, I checked the board is working with the example codes and getting detected when I use sample codes. But when coming to cayenne usb serial library, I am using the nano Serial connection library. I am getting the issues.
warning- warning: #warning “Cannot detect board type” [-Wcpp]
#warning “Cannot detect board type”
\Arduino\libraries\CayenneMQTT\src/CayenneArduinoMQTTClient.h:133:56: note: suggested alternative: ‘FPU’
publishData(SYS_CPU_SPEED_TOPIC, CAYENNE_NO_CHANNEL, F_CPU);
should I need to change everything according to the errors?
