We will have to add a new api endpoint to the TTN Mapper ingress API which handles the V4 json format. I'm not sure when I'll get around doing this.
What would help me a lot is some example uplink json events from real world networks. Access to a V4 network, application and device would be very helpful too.
OK, I have now used
tcpdump -vv -e -A
to get a real life example. So, this should be exactly how the communication reaches the ttnmapper. I changed some ID (mostly to 0) and hostnames/etc for privacy. I hope this is what you requested - otherwise contact me again. Thanks!

Hi, chirpstack has updated to v4. https://www.chirpstack.io/docs/ I tried the integration as suggested with your documentation. As far as I know Orne Brocaar tried to make chirpstack more ttn syntax like (at least the device decoders are). The data object is also different from before.
See https://www.chirpstack.io/docs/chirpstack/integrations/events.html for updated event data-structure: e.g. see up-event - mind the
object
-object:{ "deduplicationId": "3ac7e3c4-4401-4b8d-9386-a5c902f9202d", "time": "2022-07-18T09:34:15.775023242+00:00", "deviceInfo": { "tenantId": "52f14cd4-c6f1-4fbd-8f87-4025e1d49242", "tenantName": "ChirpStack", "applicationId": "17c82e96-be03-4f38-aef3-f83d48582d97", "applicationName": "Test application", "deviceProfileId": "14855bf7-d10d-4aee-b618-ebfcb64dc7ad", "deviceProfileName": "Test device-profile", "deviceName": "Test device", "devEui": "0101010101010101", "tags": { "key": "value" } }, "devAddr": "00189440", "dr": 1, "fPort": 1, "data": "qg==", "object": { "latitude":0.00, "longitude":0.00, "altitude":0.00, "hdop":0, "satellites":0 }, "rxInfo": [{ "gatewayId": "0016c001f153a14c", "uplinkId": 4217106255, "rssi": -36, "snr": 10.5, "context": "E3OWOQ==", "metadata": { "region_name": "eu868", "region_common_name": "EU868" } }], "txInfo": { "frequency": 867100000, "modulation": { "lora": { "bandwidth": 125000, "spreadingFactor": 11, "codeRate": "CR_4_5" } } } }
BEFORE (version 3. https://www.chirpstack.io/application-server/integrations/events/ ) it has been like this - mind the
