Wistoolbox and confirmation of message?

LPWAN Modules / EVBs RAK3172
1

Newbie here,

I am playing with the things stack sandbox and a RAK3173.
My gateways are about 500m away.
Sometimes the messages I send through WisToolBox are not visible on the life data in the sandbox. I do monitor the current usage through the power profiler Kit II (and setting the voltage to e.g. 3.0V).

Any idea how I can get a confirmation in WisToolBox and if there is no acknowledge, can WisToolBox retransmit?

Can you give more details?

How are you using WisToolBox to send packets?

What gateways are you using? If RAKwireless Edge Gateways, can you check in the packet log if the packets are showing up?

Hi Bernd,

I use the ttn sandbox look at the image

I type in the message see jpg.
There is also a bug in wistoolbox: The receive port is set to 0. I cannot send to that port from the sandbox.

Anyway,
Now you have some info.
I use RUI_4.2.0_RAK3172-E as firmware.

Any idea how I can get a confirmation in WisToolBox and if there is no acknowledge, can WisToolBox retransmit?

A few days ago, I could not join any local ttn gateway, only packets showed up in the sandbox from a gateway 15km away. No join confirmation. Then I used KPN network and that one worked flawlessly. KPN even showed my location using estimated time of arrival from 6 -10 gateways. But KPN wants to get money for usage.
Question? Is the TTN network reliable?

WisToolBox does not show uplinks. It is a tool to setup devices and test basic communication.

LoRaWAN allows ports starting from 0, it is not a bug in WisToolBox that it shows that port number. You have to set the port you want to use before sending a packet.

If you want to see confirmation, you will see them only in the WisToolBox console.
I am using a “normal” serial terminal app to communicate with my devices for testing.

AT+SEND=2:aabbccddeeff

will send over fPort 2 the payload aabbccddeeff
then you will see in the serial terminal the feedback for it

I have no problems with TTN’s LoRaWAN server, but I have my own gateways for testing.
15km distance could be a problem with the connection to the gateway you are using.

But honestly, I am prefer to use self hosted Chirpstack LNS on a VPN and my own gateways. In my region there are no TTN (or other free network) gateways at all.
