Hi Andreas Zolliker,

Can you refresh the web page – LoRa Network Server and see if it will display with more options on this page – i.e: ‘channel plan’ option ?

If so, could you make sure to set it to ‘EU868’ instead of ‘US915’.

If not, try to reboot the unit and check it again.

Also, what firmware version on your mDot ? Issue the command: ati

Otherwise, create a support portal case at http://www.multitech.com

Thanks,

BT

Ok the refresh actually enabled more options on the conduit. I changed the channel plan option to EU868 there.

As on the mDot I have FW mdot-firmware-1.0.8-1 installed. Although the DETAILS.TXT says:

Version: 0221
Build: Apr 29 2015 13:11:12

But ati shows:

ati
MultiTech mDot
Firmware: 1.0.8-1
Library : 1.0.8-1

Anyway, changing to EU868 did the trick – thank you!

I am having the same issue “at+join Failed to join network ERROR”.

I have upgraded the mdot and conduit software.

I have verified my network ID and Password with the conduit.

My at&v is exactly as above except for the network ID and Passwphrase.

My lora network configuration is same as here : https://picload.org/view/rdooopcg/server_config.png.html except for the network ID and password.

I have moved the conduit and mdot near each other for reducing the possibility of inereference.

Still i get the join network error.

Hi Sandoche Balakrichenan,

I am assuming that – You have tried what Andreas Zolliker did above (refresh the web page to reveal more options in Setup -> Lora Network Server web page – and set the ‘Channel Plan’ option (either EU868 or US915) according to your MTAC-LORA card) and it still did not work for you. If so, have you tried the following:

a. Factory default the Conduit and reconfigure it.

http://www.multitech.net/developer/products/conduit/resetting-the-device/

b. Factory default the mDot with the following commands:

at&f

at&w

Then reconfigure it

c. If it is still not helping, please create a support case at http://www.multitech.com

Thanks,

BT
