I want a forwarder application in drawing. It will listen two ports 1691 and 1692 locally. It will open socket connection to 1681, 1682, 1683, 1684, 1685, 1686, 1687, 1688. All communication would be UDP. * When Lora App connect to 1691 port, get UDP data. If size of data is lower than 150 then discard this data. If size of data is greater then 150 then this data would be like b'\x02D\xde\x00\xaaUZ\x00\x00\x00\x00\x00{"rxpk":[{"jver":1,"tmst":142911235,"tm32":278192252,"chan":2,"rfch":1,"freq":868.5,"mid": 2,"stat":1,"modu":"LORA","datr":"SF12BW125","codr":"4/5","rssis":-103,"lsnr":-10.9,"foff":-60,"rssi":-94,"size":52,"data":"4ErGivr741rV/MdxOOElopwmhaTQySlpiROGn8oBV8JG3/GUBciYK9te3Gjf+eEi1Ae51A=="}]}' Check rssis field. If rssis value is greater than -50. Again discard data If rssis value is lower than -50 then I want to forward this data 1681,1682,1683,1684,1685,1686,1687,1688. We are already opened socket connections to these ports. Before semding data i want to change some fields for each port. RSSIS : [-5, -6, -8, -6, -5, -7, -6 ,-7]; Add rssis value to these for each port LSNR : [0.3, -0.6, -1.8, 1.5, 0.4, -0.1, -0.9, 1.2]; Add lsnr value to these for each port TMST : [22, 13, 69, 34, 15, 11, 44, 55]; Add tmst value to these for each port After changing these 3 field then forward data to these ports. * When Lora app connect to 1692 port, get UDP data. Also, store Lora app connection port. We will use this port in another process. Forward this data directly to 1681,1682,1683,1684,1685,1686,1687,1688. * If any data comes from 1681,1682,1683,1684,1685,1686,1687,1688 connections. Get data Check size of data. If data size is lower than 150 then discard this data If data size is greater than 150. This data would be like b'\x02\x17$\x03{"txpk":{"imme":true,"freq":867.3,"rfch":0,"powe":11,"modu":"LORA","datr":"SF7BW125","codr":"4/5","ipol":false,"prea":null,"data":"4NnJATIzDXSkYMwKYYvqLsfpISJzCsigSNeWPxPFx0YpUDcTbNjT9e9UdqJcWlsKHkQoBQ==","size":52}}' Forward this data directly to stored port at upper process This forwarder application would be in C language. Forwarding process time is very important. Should be lower than 1 ms.

Hi, I specialize in low-latency C network applications and can build your UDP forwarder with precise timing (<1ms), proper socket handling, and dynamic payload modifications as described. Your requirements are clear—just to confirm, should the JSON parsing be fully dynamic in case additional fields appear in future payloads, or strictly based on the current structure? Looking forward to collaborating on this. Regards.
