LoraWan OTAA example without antenna
-
Hi Everyone,
I am trying to run LoraWann OTTA example from the documentation. I made an application on TTN and pasted the app eui and key in the code. I accidentally run the code without antenna attached.. Now when i plugged the antennas and ran the code again its not showing anything and lora.has_joined() is alwasy false. Is running the lora without antennas damages the lora ? or its just some other problem? Thanks... -
Hi,
We don't recommend running the LoRa radio without an antenna because it does have the potential to damage the radio. Personally, I have done this multiple times by accident and have never managed to damage the radio. I would recommend double checking your settings, frequencies, IDs etc to rule out the issue being with something else.

@seb Thanks for the reply, i am using this code
https://github.com/Bucknalla/lopy-raspberrypi/blob/master/lopy/main.py
After registering to the TTN network , when i run the code with my eui and key the status at the ttn page is connected and i get activation message at the data tab after every 15 or 30 seconds.. but on the lopy console lora.has_joined() is always false... -
Just to verify, have you updated your device to the latest firmware? And how far away are you from the gateway?
-
@seb Yes i updated to the latest firmware, and i dont have my own gateway.. I just know that i come in the radius of the nearest gateway in TTN..

Hi @hsn548,
Which country are you in please? (Or LoRAWAN region if you know)
The radius of the nearest gateway in TTN also tends to be very optimistic. Have you tried it outside?

@jmarcelino I am in Stuttgart, Germany.. I just put it near my window.. :|

@jmarcelino Is the activation messages after every 15 or 30 seconds normal?
-
@hsn548
What do you mean? Activation messages where? -
@jmarcelino The activation in the data tab of TTN application.. https://ibb(dot)co/kk3AFn

@hsn548
If you only see the activation messages 30 seconds after you're probably too far away from the gateway and it's only picking up some of them. -
@jmarcelino yup, thanks a lot.. i tried it outside and succeeded in getting the payloads as well..
