Downlink and Uplink over SPI in bridge mode

Hi leapslabs,

I made modifications on the user application part of the tags’ firmware and now tags are capable of reading and processing downlink iot data, thanks to USER_DATA_EVENT interrupts. Therefore, I need to regularly send downlink data to the tags. There are some questions about this:

  • How can I make sure that my iot data message is received from the tag? Can there be missed packets?

  • In a large network with multiple bridge nodes (assume 3 gateways, one is proxy-server host, as in DWM1001 Gateway Quick Deployment Guide, Figure 15), who delivers the downlink data to the tag connected with the bridge node G3? And to which broker address and port the downlink data should be sent for this tag?

Thanks in advance.
