Ingestion API from Particle platform with the board Particle Argon and they publications

#1

Hello

I’m trying to perform a data ingestion from Particle platform publications, which are the data received by connected sensors.

In this case, an AS7341 sensor reflects 11 color bands, all in a JSON array.

I also see the data collected by the AmbiMate sensor and its various sensed data.

When I created the project, I followed these step-by-step instructions: Edge Impulse training data acquisition over LTE with Particle

Without getting any evidence from the Particle Webhook, the following error is displayed when sending events:

error status 422 from ingestion.edgeimpulse.com

And this is the event I sent.

[0.010921,0.015790,0.022148,0.027282,0.000000,0.000000,0.029577,0.028478,0.032318,0.036325,0.121745,0.049110]

Hello @DavidC24,

Could you share how you configured the payload in the extra settings please?

Best,

Hi Louis.
That was the Payload cuntom:

{
“payload”: {
“device_name”: “test-som”,
“device_type”: “msom”,
“interval_ms”: 15000,
“sensors”: [
{
“name”: “Light_Spectrum”,
“units”: “nm”
}
],
“values”: [
{{{PARTICLE_EVENT_VALUE}}}
]
},
“protected”: {
“alg”: “none”,
“ver”: “v1”
},
“signature”: “00”
}

Thanks.

I think I understand the error, I believe you would need one sensor per value.
See the example of a raw requests here: Ingestion API | Edge Impulse API and SDKs Documentation

If you have 11 values you would need to do something like the following:

{
“payload”: {
“device_name”: “test-som”,
“device_type”: “msom”,
“interval_ms”: 15000,
“sensors”: [
{
“name”: “Light_Spectrum_1”,
“units”: “nm”
},
{
“name”: “Light_Spectrum_2”,
“units”: “nm”
},
...
{
“name”: “Light_Spectrum_11”,
“units”: “nm”
}
],
“values”: [
{{{PARTICLE_EVENT_VALUE}}}
]
},
“protected”: {
“alg”: “none”,
“ver”: “v1”
},
“signature”: “00”
}

Let me know if that helps.

Best,

Louis

Passing values as separate sensors like Louis said or if you want to pass it as you had you need to format the Array properly (it was resolving as a String)

Wrong: This passes a String

“values”: [
{{{PARTICLE_EVENT_VALUE}}}
]

Correct: To pass as an Array try:

“values”: [
[{{PARTICLE_EVENT_VALUE}}]
]

Hi, I try different ways to configure JSON and Webhook, but the error persist. That’s the last JSON format to I used:

{
“payload”: {
“device_name”: “AS7341”,
“device_type”: “EDGE_IMPULSE_UPLOADER”,
“interval_ms”: 60000,
“sensors”: [
{“name”: “Light_Spectrum_0”, “units”: “nm”},
{“name”: “Light_Spectrum_1”, “units”: “nm”},
{“name”: “Light_Spectrum_2”, “units”: “nm”},
{“name”: “Light_Spectrum_3”, “units”: “nm”},
{“name”: “Light_Spectrum_6”, “units”: “nm”},
{“name”: “Light_Spectrum_7”, “units”: “nm”},
{“name”: “Light_Spectrum_8”, “units”: “nm”},
{“name”: “Light_Spectrum_9”, “units”: “nm”},
{“name”: “Light_Spectrum_10”, “units”: “nm”}
],
“values”: [
[{{PARTICLE_EVENT_VALUE}}]
]
},
“protected”: {
“ver”: “v1”,
“alg”: “none”
},
“signature”: “0”
}
