AT firmware: raw tx

[Chris Schramm]

Dear All,

I’ve just received our mDot and Micro Dev Kit. Connection via UART is successful and I wonder if there is any AT command for sending raw loramac packets. I know there are already recent threads about LoRa mode but they’re not specific to the AT command firmware which I prefer to use to keep things simple.
Use case: we have a Laird gateway here in our office and for the testing I just want to have the mDot 100m away from the office and repeatedly send some data w/o the LoRaWan overhead (I don’t care about encryption etc)

Sorry, there is not a command to send raw LoRa packets in the AT firmware or libmDot libraries.

Closest thing would be to set in MANUAL mode
AT+NJM=0

The ADDR can be set with
AT+NA=00112233

Uplink counter can be adjusted with
AT+ULC=1

And disable encryption of the payload
AT+ENC=0

The header and MIC will still be in the packet

thank you for the really quick reply!
Alright, is there any really simple example for sending raw messages?
