Thanks effesud,
This looks great for prototyping. I just ordered one, but will have to wait as it is not in stock.

Hi Tim,
i have undergo a same punishment that you…
You can change EUI device and others parameters with using putty but you must change length in receive string in your source code (usb_user.c ) For example in line 1886, change " if (strlen(pcInStr)!= 29)" by 28 and do not 29. Anothers lines must be changed.
For ST team, check you document ! You have recently update release version to 2.0.1, and not the text in projects (Ex: Readme.txt)
Is the firmware defaulting to EU frequencies? Do you have to reflash it to set the frequency to the US bands?
Hi KE6MTO,
yes, the firmware is by default configured for EU868 frequency band.
You can change it to US915 in the compiler preprocessor options.
Just connect device with my Android mi A2 phone using the provideded USB-C cable. I can use Serial USB Terminal app to connect the device via CDC driver. This will give both charging and terminal features.
Following this thread and various sources online, I have manged to get the tracker going without compiling the firmware using the following method:
Program & Verify
and select the file from the downloaded software package: /STM32CubeFunctionPack_LORA1_V2.0.1/Projects/STEVAL-STRKT01/Applications/LoRa/Asset_Tracker/Binary/STEVAL_STRKT01.bin
!deviceeui-xxxxxx
!joineui-xxxxxx
!appkey-xxxxxx
!ntwkkey-xxxxxx
!sysreset
Hi All,
I finally received my TTIN gateway, and got my first connection.
So thanks again, effesud, that was a good move.
Now I need to decode the payload. I suppose that there is something for that, but the doc is not very clear.
After a while I understood that one has just to check in
Cayenne LPP in Applications -> Payload Formats,
and everything is automatic as it ahs been properly encoded
in main.c, lines 1319 – 1363
I have now
{
“accelerometer_4”: {
“x”: 0,
“y”: -0.029,
“z”: -0.97
},
“analog_in_5”: 3.89,
“barometric_pressure_0”: 1009.3,
“digital_out_6”: 0,
“gps_3”: {
“altitude”: 106.64,
“latitude”: 48.xxx,
“longitude”: 2.xxx
},
“relative_humidity_2”: 37.5,
“temperature_1”: 29.2
}
which looks OK.
Hope this will help someone.
and as a streched goal get it to run Mbed OS 5
Note that this is the same module as on the DISCO-L072CZ-LRWAN1 board so compiling for that target from Mbed CLI / Online Compiler should give you a binary that can also run Mbed OS on this module. There seem to be drivers for the GNSS module as well from ST: TeseoLocation.
I have received my TTIG, and I am experimenting with a
STEVAL-STRK01, sending a message every minute, but I see that several packets are lost.
Packets are received more like every 2 mn.
And more important, after a while (33 packets) everything is stalled.
Where does the problem come from ?
this is not related to TTIG imho…
I dont understand what you mean.
I wrote that I received 33 packets : so it worked.
The problem is that after a while ( less than one hour), the packets are no longer forwarded.
I see… ok, TTIG is working fine (here) so it must be your node (code)
-is the green led flashing when its no longer forwarding ?
-are you moving around with the node ?
The green led is fixed.
The node does not move.
I want to know how steady the connection can be. Up to now, it is not very successful.

It seems that packet 4 is missing. Why ?
can you try move it further away from TTIG ?
I move it a little bit further

The Payload is 37 bytes
what is ADR ( and where ) ?
what do you mean by “lower the interval” ?
