Hello,
Thank you for maintaining this great software.-
We have recently acquired an amazing Milesight SG50 with external 45W solar panel.
We are facing an integration problem :
Milesight SG50 does not support Chirpstack > v4.0.0 when using MQTT regional topic f.e. “eu868” topic prefix.
The possible solutions and drawbacks.
1.- Implement a service which republishes everything bellow gateway/xxxxxx to eu868/gateway/xxxx. This solution add an extra service with additional costs and maintenance requirements.
We have implemented the microservice but we can’t still see the gateway ONLINE.
This is a WORKING kerlink gateway STATS Message :
eu868/gateway/7076ff005606xxxx/event/stats {“gatewayId”:“7076ff005606xxxx”,“time”:“2024-06-05T14:43:08+00:00”,“rxPacketsReceived”:76,“rxPacketsReceivedOk”:72,“txPacketsReceived”:1,“txPacketsEmitted”:1,“metadata”:{“mqtt_forwarder_version”:“4.2.0”},“txPacketsPerFrequency”:{“868300000”:1},“rxPacketsPerFrequency”:{“867900000”:1,“868500000”:2,“868100000”:18,“867100000”:1,“868300000”:50},“txPacketsPerModulation”:[{“modulation”:{“lora”:{“bandwidth”:125000,“spreadingFactor”:7,“codeRate”:“CR_4_5”,“polarizationInversion”:true}},“count”:1}],“rxPacketsPerModulation”:[{“modulation”:{“lora”:{“bandwidth”:125000,“spreadingFactor”:12,“codeRate”:“CR_4_5”}},“count”:3},{“modulation”:{“lora”:{“bandwidth”:125000,“spreadingFactor”:7,“codeRate”:“CR_4_5”}},“count”:69}],“txPacketsPerStatus”:{“OK”:1}}
Notice : SG-50 is sending the gateway id in protobuf format.
This is a FAILING Milesight SG-50 gateway STATS Message processed by topic switch microservice :
eu868/gateway/24e124fffef9xxxx/event/stats {“gatewayID”:“JOEk//75APk=”,“ip”:“10.56.26.4”,“time”:“2024-06-05T14:41:36Z”,“location”:{“latitude”:88.0xxxx,“longitude”:2.1xxxx,“altitude”:88.0,“source”:“GPS”},“configVersion”:“”,“rxPacketsReceived”:12,“rxPacketsReceivedOK”:9,“txPacketsReceived”:0,“txPacketsEmitted”:0}
2.- Connect using semtech udp/1700. This solution is not feasible as gateway uses celular network with CGNAT (carrier grade nat) , no public IP , no able to reach gateway udp/1700. unsecure , unencrypted.
3.- Downgrade to <4.0 chirpstack version.
Could you provide .deb pas for <4.0 chirpstack version ?
Milesight SG-50 for > 4.0 chirpstack with MQTT integration is not going to be supported till 2024 Q4 !!
