Async downlink #134

Open ShiawasenaHoshi opened 7 years ago

ShiawasenaHoshi commented 7 years ago

Hi, guys! There is one line in this readme https://github.com/CongducPham/LowCostLoRaGw/blob/master/gw_full_latest/README-downlink.md : "the lora_gateway.cpp program will check for a downlink.txt file after each LoRa packet reception. This behavior can be disable with --ndl option" but I'd like to check downlink independent of packet reception. Is there any ready-made solution or I need to make it by myself? Or at least send downlink after 100-1000ms gateway receive packet.

There are 2 levels for downlink, the post-processing level and the low-level gateway (i.e. lora_gateway.cpp). At post-processing, it is as you said asynchronous. At the lora_gateway level, it is triggered by packet reception. You can change this latter behavior by implementing it in lora_gateway.cpp but it has little interest as end-device may be sleeping most of the time.

regards,
