Join Lora network via OTAA With RN2483

[Asier Galech]

Hi,
I’m using conduit gateway AEP with the RN2483 module from microchip. I’ve defined the NetworkEUI and Network key correctly in the gateway. Also, I’ve added the node with the command “node add [DevAddr] [Class] [DevEUI] [AppEUI] [AppKey]”.

In RN2483 I’ve executed the following commands:

mac set devaddr 00000002
mac set deveui 0004a30b001b266a
mac set appeui yyyyyyyyyyyyyyyy
mac set appkey yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
radio set crc on
mac save
mac join otaa

RN2483 shows the message “denied”.

Upon looking at the log node-red, I’ve seen that the gateway responds “Send Join Accepted”:

Hi Asier,

Have you tried to activate it using manual mode ? Instruction is at the following link:

Thanks,

BT

Hi Bryan,

Yes, I’ve followed these instructions. With the Join AEP, it worked correctly but with Join OTAA it still returns “denied”

Thanks

Asier

Asier,

1. Do you have ‘public’ mode enable on the Conduit ? Also, can you ssh into the Conduit and issue the following command:

/opt/lora/lora-network-server –version

If it is not at 1.0.8, please upgrade them.

http://www.multitech.net/developer/downloads/

Please, make sure you have download a correct file for your model.

2. What is the value return when you issue the command – ‘radio get freq’

3. Also, if you web into the device and go to Lora Network server -> Network server log -> Select TRACE. Click on ‘Submit’ button. Then ssh into the Conduit and issue the following command:

tail -f /var/log/messages | grep lora

This will get you more debug messages.

Thank you,

BT

Hi,

1. Public mode is enabled. The version wasn’t 1.0.8. I upgraded it but the Join OTAA still return “denied”.

Upon looking at the log lora-network, I’ve seen that the gateway responds “Send Join Accepted”:

2. The command ‘radio get freq’ returns the value ‘869500000’

Thanks

Hi Asier,

Could you please issue the following command to the RN2483:

radio set freq 868500000

And see if it helps ?

Thank you,

BT

[Asier Galech]

Hi Bryam,

The same problem in applying the command.

Thanks

Asier

[Bryan Tran]

Asier,

Can you check with Microchip to see if they have any latest firmware and see if it helps ? I am using the following firmware version:

invalid_param

mac get deveui

0000000000000000

mac set deveui 0204A30B001A53B2

ok

mac get deveui

mac set appkey e9b99fe1c9ba8d3efa562eb1ac02c331 <–YOUR-NETWORK-PASSPHRASE3

ok

mac get appkey

invalid_param

radio set crc on

ok

mac save

ok

radio get freq

868100000 <–May be try with 868100000 and see if it helps ?

mac join otaa

ok

accepted

mac join otaa

ok

mac join otaa

ok

and it is working fine for me.

Thank you,

You have to be on latest RN2483 firmware to get OTAA.
I have tested with customer who is using OTAA.
We have also tested downlink to RN2483 all workin.

[Asier Galech]

Hi,

With the latest RN2483 firmware, OTAA worked correctly.

Thanks
