Sorry for the late reply and thanks for your answer!

the problem I was having was that i wanted to send hex values like {03 01 01} via CLI.
that worked fine, but when i meant to send something like {03 0A 01}
The CLI interpreted that '0A' as I had finished the command sending only '03' instead of sending the full {03 0A 01}

You need to put space instead of new line before you put a new argument. Pressing enter - producing '\r' or '\n' or '\r\n' - this basically how all command line tools works (enter means - "I finished my command, please execute it").[/quote]

I was able to find the correct file to adapt the CLI code HERE,

[quote userid="5630" url="~/f/nordic-q-a/42308/nrf52840-cli-udp-mqtt-sn-commands/165632"]Do you mean that you want to have CLI based MQTT-SN commands? If yes, then i suggest you to take a look on this API to register custom commands. You can't just use "udp send" command to emulate MQTT-SN behaviour. You would need to map MQTT-SN API to CLI commands.[/quote]

Yeah, I was planning to do something like that, but now I'd like to go further and try to that by implementing the spinel protocol

Thanks again!

Hello Tiago Morais,

First of all, thank you for using nRF5 SDK for Thread and Zigbee!

I'm not sure if i understand the nature of the problem, so i will just list couple of thoughts after reading your post.

1. The "udp send" command is documented in the README_UDP.md file. You need to put space instead of new line before you put a new argument. Pressing enter - producing '\r' or '\n' or '\r\n' - this basically how all command line tools works (enter means - "I finished my command, please execute it").

2. You can configure your serial communicator (e.g. Putty) to use any of the mentioned above new line breaks.

3. You said:

[quote userid="76337" url="~/f/nordic-q-a/42308/nrf52840-cli-udp-mqtt-sn-commands"]I don't want to keep the mqtt-sn client inside the nrf52840, I'd like to put it in a microcontroler.[/quote]

Do you mean that you want to have CLI based MQTT-SN commands? If yes, then i suggest you to take a look on this API to register custom commands. You can't just use "udp send" command to emulate MQTT-SN behaviour. You would need to map MQTT-SN API to CLI commands.

4. Anyway, if i didn't understand the problem correctly, you can always make some modification to the CLI application and update OpenThread libraries inside SDK.

Łukasz
