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

[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

[gerkez]

@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

[Shaun]

@gerkez Ok, then you should not be experiance problems from rf reflections, and should be able to rule it out.
I doubt you are working on a conductive table ;-)

Hello,

first of all, the LoraWAN Nano Gateway works great!!

I used the HTTP Intergration of the TTN it post the received data to my PHP script and the PHP script placed the data in my own database.

I have used the HTTP intergration below.

https://www.thethingsnetwork.org/docs/applications/http/

I see that is possible that I can receive also the Latitude, longitude and altitude of the device. without place this in the payload, but this is not implement in python script.
Is it possible to implement this in python without put this values in the raw payload?

"latitude": 52.2345,               // Latitude of the device
"longitude": 6.2345,              // Longitude of the device
"altitude": 2                            // Altitude of the device

Best Regards,
Mark

Hi,

Will the nano gateway work with any node or just Lopys? For example, will Multitech's mDot work?

Javier

@daniel
I just upgraded my board and see - but no info about this version

(sysname='WiPy', nodename='WiPy', release='1.6.8.b1', version='v1.8.6-504-gff1098f6 on 2017-03-13', machine='WiPy with ESP32')

also after upgrade i now have:

OSError: I2C bus error
