Hi guys,
I’m trying to schedule a downlink by publishing to mqtt using python. Here is my implementation in Python
but ChirpStack keep throwing the error " Handling downlink command error
dev_eui =6998f55bfbb18223
error =Exception generated by quickjs: []:1 unexpected token: ‘object’". Here is my implementation of the encoder, for now I only want to send a basic “Hello World” back to my Arduino
Does anyone have a clue, how can I resolve this problem? I very appreciate your help. Thank you!
try sending like this… (sorry this is from curl but i’m sure you’re smart enough to see the json in the payload)
mosquitto_pub -d -h mqtt.example.com -p 1883 -u <USERNAME> -P <PASSWORD> -t 'application/<TENANT_ID>/device/<DEVICE_EUI>/command/down' -m '{"devEui": "<DEVICE_EUI (must match mqtt topic)>", "confirmed": true, "fPort": 129, "data": "AgAHAAgBAwADAAF0Cg=="}'
the encodedDownlink(input)
will return data
as an object to to extract this use something like
let data = input.data;
hope this makes sense.
