Answer
No, not in the initial release of firmware. Only a single message can be submitted for transmission. If subsequent messages are submitted, they will overwrite the existing message until it has been transmitted.
This might not be an issue for event based reporting but could be an issue if multiple messages or packets need to be sent in quick succession.
We will be adding extra functionality to better manage message queuing in time. Please check the firmware release notes for fuirther information or contact support@lairdconnect.com
