mDot_LoRa_Connect_Example join problem

[Bernaud Benjamin]

Hello,

In the 1st time I used the AT command to work on the mdot_lora.
Now I want to use the mDot_LoRa_Connect_Example.

In the 1st case (with AT command) the join and the send are available
Now (with the example), I don’t receive join accepts. My programme is blocked in the dot->joinNetwork().

But, when I subscribe at all topics with mosquitto I can see the same message:
Lora/xxxx/packet_recv {…}
Lora/xxxx/joined (null)
Lora/xxxx/packet_sent {…}

And in the gateway I log in max (100). I check the behaviour (tail -f /var/log/Lora-network-server.log). In the AT case the server understands the request, but not in the mDot_LoRa_Connect_Example case.

So, I’ve a join request, but I don’t receive the join accepts. What is the problem?

Thanks,
BERNAUD Benjamin

Hi Bernaud,

1. Which firmware version do you have on the Conduit ? Make sure you have upgrade them to a latest firmware.

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

For the mLinux: Download and install the following:

– Download Lora Network Server 1.0.8 (Changelog | Upgrade Instructions)
– Download Lora Packet Forwarder 1.4.1-r9 (Upgrade Instructions)
– Download Lora Query Utility 1.0.2

For the AEP: Please, download and install the following:

– Download version 1.1.2 (Changelog | Upgrade Instructions)
– Download Lora Network Server 1.0.8 (Changelog | Upgrade Instructions)

2. Which firmware version do you have on the mDot ? Make sure you have a latest firmware on it.

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

The AT command firmware is:

– Download version 1.0.8 (Changelog | Upgrade Instructions)

For the mBed online/off line version:

– libmDot-1.0.8-1

3. If after upgrade them and you are still having a problem, please post the configuration of both mDot and Conduit.

a. ssh into the Conduit and do the command:

cat /var/config/lora/lora-network-server.conf

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

opkg list | grep lora

b. For the mDot:

With AT command firmware, do:

ATI

AT&V

With mBed online firmware, we need the output of the function:

logInfo(“version: %s”, dot->getId().c_str());

static std::string config_network_name = “xxxx”;
static std::string config_network_pass = “xxxxx”;
static uint8_t config_frequency_sub_band = x;

Thanks,

BT

Hi Bryan,

I use mLinux and mBed online.
I take this libmDot 1.0.8-1:
https://developer.mbed.org/teams/MultiTech/code/libmDot/rev/5fddfa2b85aa

In my gateway the problem is resolved. It understands the request and resend the accepts. But I always blocked in the join Network function.

Thanks for your help.
Benjamin.

Hi Benjamin,

The mBed online version is setting – the ‘Public’ mode to True by default. So, try to set your /var/config/lora/lora-network-server.conf on the Conduit to True too and see if it helps.

———————————————————————
…

“network”: {
“public”: false, <–Set this to true
“leasetime”: 0, /* time until mDot join expires (minutes) or 0 for no expiration */
“name”: “my Name”,
“passphrase”: “my Pass”
}

….
——————————————————————–

And then do: /etc/init.d/lora-network-server restart

Thanks,

BT

This appears to be a problem with recent versions of mbed-rtos. Use the revision tab in the online compiler to revert the library to revision 111.

[Bernaud Benjamin]

Hi Bryan,

It’s successful.
I changed in public mode, but I must use the appEui and appKey to connect my Mdot and my gateway.
So I use this code in bed online: https://developer.mbed.org/teams/MultiTech/code/mDot_LoRa_Connect_Example_APP_EUI_KEY/

Thanks you very much for your help.

Benjamin.

[Bryan Tran]

Hi Benjamin,

Can you try what Jonathan suggested and let me know if it helps ?

Thanks,

BT

[Bernaud Benjamin]

Hi Jonathan,

I try your solution with the name and the Passphrase, in private and public stats. The revision doesn’t work. My gateway understand, but not my mdot (version: 1.0.8-1-g7ae9ef7). It’s blocked in join Network ().

Thanks,

Benjamin.

Bernaud,

v111 and v107 are known to work.
