const DefaultClassBTimeout = 10 * time.Minute

DefaultClassBTimeout is the default time-out for the device to respond to class B downlink messages. When waiting for a response times out, the downlink message is considered lost, and the downlink task triggers again.

View Source 
const DefaultClassCTimeout = 5 * time.Minute

DefaultClassCTimeout is the default time-out for the device to respond to class C downlink messages. When waiting for a response times out, the downlink message is considered lost, and the downlink task triggers again.
