RAK5205 WisTrio kit problems

I have a RAK5205 WisTrio kit and a RAK7258 gateway.

I was able to update the firmware on both the kit and the gateway from the Rak downloads site here:

I have the gateway set up and the WisTrio connected to it. I get messages in the live data feed on the gateway from the sensor but they are lacking any real information. I see temp, humidity, acceleration, and pressure in the RAK Serial Port Tool but do not see any of that at the gateway.

Here is what I see as a message at the gateway:

“applicationID”: “1”,
“applicationName”: “RAK Test”,
“devEUI”: “9c912623c37b6fff”,
“deviceName”: “RAK811”,
“timestamp”: 1566970348,
“fCnt”: 5890,
“fPort”: 3,
“adr”: true,

“location”: {
“latitude”: 0,
“longitude”: 0,
“altitude”: 0
“txInfo”: {
“frequency”: 927500000,
“dr”: 13

Here is what I see on the Serial Tool:

Wake up.
Battery Voltage = 3.795 V

Humidity:42.0 %RH
pressure:999.0 hPa

[LoRa]: Send out
[LoRa]: Unconfirm data send OK
Go to Sleep.

Also the GPS refuses to turn back on with the AT command:


Hello, @cowbear. Thank you for the post.

Could you please share a link to the instructions you are following? Any resources to recreate your issue will be helpful.


I’m using these for the sensor instruction:

And these for the gateway:

I found that the gateway is actually getting the data based on the RAK52025_V3.x_Packet_Decode.pdf but is not parsing it into the message information in any way. I found that my device was not responding to any AT commands so I erased it, reburned the boot loader and reflashed it with the newest firmware. I don’t know how to recreate the issue with it not responding to AT commands.

After reflashing and reconnecting it, I was able to get GPS when I went outside but noticed it would always resend the same GPS information every packet. Under what conditions does it try to get new GPS coordinates other than a restart?

@cowbear As per the documentation: https://github.com/96boards/documentation/blob/master/iot/wistrio/installation/linux.md

For getting the AT command response, Local echo needs to be turned ON. On minicom, this can be achieved by Ctrl + A, E. After entering the AT commands, press Ctrl + J

I’m not using Linux. I am using windows with the RAK Serial Tool. The sensor started out taking AT commands and at some point stopped until I reflashed the firmware.
