does this mean GW accepted the join requires? but i always got reply from RN2903 radio shows “denied”, here is what i did in the RN2903 radio
————–
RN2903 0.9.5 Sep 02 2015 17:19:55
mac set deveui 0123456789ABCDEF
ok
mac set appeui 0200000000eeffc0
ok
mac set appkey 2B7E151628AED2A6ABF7158809CF4F3C
ok
mac save
ok
mac join otaa
ok
denied
———–
follow the RN2903 description of “denied”, it is caused by GW rejected join requires. can you help me figure out what is wrong in there? thank you

Hi,

I’m using the RN2483 and have the same problem. Currently no solution using the default lorawan server.

Frederik

Hi,

Have you tried to activate it using manual mode ?

Conduit:
——–

mLinux:

ssh into the Conduit and issue the following:

# nc -u localhost 6677

Then add a node like this:
# node add [DevAddr] [APPEUI] [DEVEUI] [NwkSKey] [AppSKey]

Example:
# nc -u localhost 6677
node add 00000005 0011223344556677 8811223344556677 2b7e151628aed2a6abf7158809cf4f3c 2b7e151628aed2a6abf7158809cf4f3c

AEP:

a. Web into the Conduit and go Setup -> Lora Network Server -> Click on ‘Enable’ -> Public -> ‘Enable’ -> Name: YOUR-NETWORK-NAME -> Passphrase: YOUR-NETWORK-PASSPHRASE.

b. Click ‘Submit’ button.

c. ssh into the Conduit and issue the following:

nc -u localhost 6677
node add 00000005 0011223344556677 8811223344556677 2b7e151628aed2a6abf7158809cf4f3c 2b7e151628aed2a6abf7158809cf4f3c

Microchip:

mac set devaddr 00000005

mac set nwkskey 2b7e151628aed2a6abf7158809cf4f3c

mac set appskey 2b7e151628aed2a6abf7158809cf4f3c

radio set crc on

mac save

mac join abp

mac tx cnf 1 123456

Thanks,

BT

thanks for your replies, i have success joined the GW with OTAA and ABP mode with RN2903 radio 🙂
i don’t know why, i used serial console to input commands of RN2903 to join the GW with OTAA, it is hard to get it Joined, but when i use program (serial program to connect to RN2903 serial port), i can join the GW, it is weird. but anyway, now RN2903 working for me now 🙂

Hi,

I’ve been following these notes but I’m still having issues with sending data. Joining does not appear to be my issue but sending data does.
I’m manually adding node using SSH and using node add instruction but can you point me to a remove instruction – I would expect some documentation around this but I can not find it.

By the way, this is references RN2483.
