New firmware release 1.6.7.b1 (LoRaWAN Nano Gateway with TTN example!!)

@rskoniec I'm also seeing those and I'm investigating the cause together with Espressif.

OK, thank you @daniel I hope you'll find the cause of those.

@Movsun just change the bandwidth (to make it 250 KHz) argument in the LoRa constructor for both LoPy's.

[jomifo]

@daniel +1 to see code adapted for US frequencies.

Hello Daniel,

You promised weeks ago (around build 1.3.0) that you will enable frozen bytecode. When this will happen?

[johncaipa]

Is there anyone who has tested how many nodes could be received in practice with the nano-gateway?

[Colateral]

@johncaipa So far we tested with 7 nodes .... but not with pycom nano-gw example.

Hello Daniel,

The scripts look great, but I don't seem to get them working.
I have created a gateway in the TTN console, but the gateway doesn't connect.
I have a WiFi connection to my router, so that is not the problem.

In your config.py:
the GATEWAY_ID = '11aa334455bb7788'. Where did you get this ID?
I created my own ID when I registered a gateway at TTN console.
Can I leave the LORA_DR = "SF7BW125" # DR_5 unchanged?

In the nanogateway.py:
def stop(self):
# TODO: Check how to stop the NTP sync
# TODO: Create a cancel method for the alarm
# TODO: kill the UDP thread
self.sock.close()
I have no idea how to handle those TODO's.
Can you give some examples?

Hopefully you can help a newbee to get this working.
Thanks

GerkeZ

@gerkez you can put there in the Gateway ID that you created when registering it to TTN.

Can I leave the LORA_DR = "SF7BW125" # DR_5 unchanged?

Yes.

Don't worry about those TODO's, those will be taken care of on a future update of the nanogateway scripts.

Cheers,
Daniel

@gerkez
also make sure you have selected the "packet forwarder" protocol when registering the gateway in TTN. I think your ID question may relate to this.

[gerkez]

@daniel
Thanks. I'll try it and let you know

@jmarcelino
Hi. Thanks.
I deleted my gateway and registered a new one with the "packet forwarder" protocol.
It generates a Gateway ID based on the EUI (eui-70b3d54991ae49e8).
I tried both ID's in the config.py.
eui-70b3d54991ae49e8: script runs but the console displays "not connected".
70b3d54991ae49e8 (without prefix eui-): script runs but restarts all the time.

Here is my config.py:

GATEWAY_ID = 'eui-70b3d54991ae49e8' (not working)

GATEWAY_ID = '70b3d54991ae49e8' (infinite loop, restart)

SERVER = 'bridge.eu.thethings.network'
PORT = 1883

NTP = "pool.ntp.org"
NTP_PERIOD_S = 3600

WIFI_SSID = 'my ssid'
WIFI_PASS = 'my passwd'

LORA_FREQUENCY = 868100000
LORA_DR = "SF7BW125" # DR_5

[daniel]

The correct gateway ID to use is: 70b3d54991ae49e8

These 2 parameters are incorrect:

SERVER = 'bridge.eu.thethings.network'
PORT = 1883

Please use the same as in the example, which are:

SERVER = 'router.eu.thethings.network'
PORT = 1700

Cheers,
Daniel

Hi Guys,

Thanks a lot for helping.
I have a connection to TTN, but is seems that my lopy reboots all the time (every 30 -60 seconds).
I hav put a red led for 3 seconds in main.py and I can see this red led light up all the time and than I lose my connection (wiFi as well).
Hope you have an idea what's going wrong

@gerkez
What you got on UART REPL?
Put info here - there can be some usefull info

[gerkez]

@livius
Hello Livius,

My pymakr doesn't work. Connection errors.
So I use Putty. Problem is that the device reboots all the time, so I don't see anything on the UART REPL

[livius]

@gerkez
Try Arduino IDE -> COM port monitor instead

@Colateral
My problem was that password was not long enough. Once I changed it, it worked fine. It would be better if some indication was given about a problem from WiPy, but no big deal, once understood...!

[gerkez]

@zmrzli
Which password do you mean?

[Shaun]

@gerkez Are you using a custom base PCB (your own) or are you using the Pycom expansion PCB?
I ask, as you may be running into the WiPy resetting due to rf reflections issue.

[gerkez]

@Shaun
I am using a pycom expansion board with LoPy
