[solved] LT-33222-L LoRa I/O Controller - AT_ERROR

End Devices (Nodes) Dragino
1

I’m having troubles configuring a LT-33222 from Dragino using AT commands. On every command I get the response “AT_ERROR”.

I entered the password and the device responded with “Correct password”.
AT commands without a “+” in it like “ATZ” work fine. Commands like “AT+NJS=?” fail.
So it might be a problem with the encoding/terminal type.

If somebody has a working connection, please share your settings here.

Tnx,
Christian

Hi Christian,

it’s a brandnew device if I’m right … can’t even find the manuals online.

something else… are you ‘stuck’ ?? :wink:

I’ts very new, can’t find much about it.
Documentation is avilable here: http://www.dragino.com/downloads/downloads/LT_LoRa_IO_Controller/LT33222-L/

Stuck? - No, but the first attempt for a meetup failed due the lack of interest…

ah ok… hope it will work in the future… you’re So close becoming ‘official’

  • how do you send the AT command to the UART… with a terminal program or connected to an MCU ?
  • what voltage / speed

I know, we give it another try before Christmas :wink:

I’m using a TTL USB Serial converter attached to a Mac, 9600/8/N/1
All good with other devices, attached an Arduino to capture serial output -> data is fine.

It have a second device, going for a try with this one too.

HA! Second device is doing fine an has a newer firmware.
This one is woking fine: DRAGINO LT-33222-L Device Image Version: v1.0

I’m now going to reflash the first one with the same firmware…
