Can't connect FiPy via LoRa

[weingami]

Hello there,

currently I'm trying to connect my FiPy via LoRaWAN with OTAA to Pybytes, but it's not working. As gateway I'm using a "The Things Gateway".
Previously I was able to connect my FiPy via Wifi, which worked perfect. But with OTAA it's not even connecting.
This is what I get at Atom's Pymakr console:

Firmware: 1.18.1.r7
Pybytes: 0.9.2
Pybytes configuration read from /flash/pybytes_config.json
Unable to connect to Pybytes: 'NoneType' object has no attribute 'nvram_restore'
'NoneType' object has no attribute '__connection_status'
'NoneType' object has no attribute '__connection_status'
Pycom MicroPython 1.18.1.r7 [v1.8.6-849-ac2b18f] on 2018-12-17; FiPy with ESP32
Type "help()" for more information.
>>>

main.py:

from pysense import Pysense
from SI7006A20 import SI7006A20

py = Pysense()
si = SI7006A20(py)

pybytes.send_virtual_pin_value(True, 1, si.humidity())
pybytes.send_virtual_pin_value(True, 2, si.temperature())

Is there eventually anything I've been overlooking/doing wrong? I'm glad for any help regarding this issue.

Hey, Could you try upgrading to the latest 1.20 rc and confirming it still exists there?

@weingami My bad... something I messed up in the latest firmware. I'll fix this as soon as possible.

In the meantime you can use the beta firmware updater to downgrade to the previous Pybytes version 1.18.0.r1 (Enable the field for "Show Advanced Settings" in the Communication window).

Please excuse my late reply.

The Errormessage seems to be gone now.

Data is received acording to the dashboard

Though none of the data seems accessible:

any ideas regarding what could be wrong here?

Heya, We recently rate limited messages to pybytes to 1/second. Sadly it seems to cause issues sending multiple pin values at once in quick succession (Were working on it).

Does it work ok if you put a sleep between the calls to send_virtual_pin()

from pysense import Pysense
from SI7006A20 import SI7006A20
import time

py = Pysense()
si = SI7006A20(py)

pybytes.send_virtual_pin_value(True, 1, si.humidity())
time.sleep(1)
pybytes.send_virtual_pin_value(True, 2, si.temperature())```

Unfortuneately the issue still persists in the same manner. (It is indicated but not shown in the signal graphs) I even tried a five second sleep or just sending one value and the results were the same.
To verify everything else was working correctly I also let my FiPy connect via Wifi which worked perfectly.

Also after adding a microsoft Azure integration it came to my attention that when data is delivered via wifi azure IoT Hub indicates that data has been received, but it does not seem to receive any messages when any data is sent via LoRa even with 1.18.0.r1

@weingami I just checked with the Pybytes team they will deploy a hotfix for this on Monday.

@xykon
Sweet, that's quick customer service. Thank you!

@weingami Hi, I deployed hotfix and tested wifi, sigfox and lora connections. I correctly received the data.

We need to test more things and there are a few more bugs, that we know and we're about to fix now.
