Not getting Sensor Readings in Pysense with FiPy Module

[jcaron]

@archana-kadam are you sure you correctly re-uploaded the modified file?

[Archana Kadam]

@jcaron
Yes i re-uploaded the modified file.
Earlier it was #your_data = "Hello"

[livius]

@archana-kadam
Quite impossible on line 15 where you store text (connect to your device by ftp and look like your file really is)

but do you have host 192.168.0.109 and especially do you have something which listen on that host on port 2345?

@livius
Here is code which im using to connect to the server.

from network import WLAN
import machine
import socket

wlan = WLAN(mode=WLAN.STA)
# wlan.ifconfig(config=('192.168.0.105', '255.255.255.0', '192.168.0.1', '192.168.0.1')) - you can ommit this line if you need to connect by DHCP
wlan.connect(ssid='ssid...', auth=(WLAN.WPA2, 'passs...'), timeout=30000)

while not wlan.isconnected():
	machine.idle()

if wlan.isconnected():
	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	s.connect(socket.getaddrinfo('192.168.0.109', 80)[0][-1]) #IP of your computer(192.168.0.109) in the same network as your Fipy and port(80) of socket in listen mode on your computer
	#your_data = "Hello"
	s.send("your_data")

Yes i have the same IP address and the port is 80. By using the same code im getting an error is
Traceback (most recent call last):
File "<stdin>", line 15, in <module>
OSError: -1

@archana-kadam said in Not getting Sensor Readings in Pysense with FiPy Module:

strange because line 15 is just comment line

add this lines before socket connect

print(str(socket.getaddrinfo('192.168.0.109', 80)))
print(str(socket.getaddrinfo('192.168.0.109', 80)[0][-1]))

and put result here

Here is and code and we are getting the same errors i,e

Traceback (most recent call last):
File "<stdin>", line 14
IndentationError: unindent does not match any outer indentation level

check if you do not mix indentation as tab and space

PS. use forum formating http://commonmark.org/help/ e.g. triple ``` around the code

We are trying to run the LoRa Nano Gateway code provided in the pycom documentation. We are using three PC's and three fipy boards. In one pc we are running the Gateway.py , second we are running Node.py and in third pc we are running the RawLora.py codes. But we are getting an error in Gateway.py code in Line 26 i,e buffer too small. Is the procedure we are doing is correct? Please reply us soon as possible.
Thank You

@archana-kadam
WIthout the code i can only gues that you try to send to big data throught Lora. It is very limited. Check how much data is really sending.

[Archana Kadam]

@livius
I used the codes from provided pycom documentation. Here are the links of the code
https://docs.pycom.io/chapter/tutorials/lora/lora-mac-nano-gateway.html
https://docs.pycom.io/chapter/tutorials/lora/lora-mac.html

[livius]

@archana-kadam
in documentation gateway line 26 is empty...
You have some modification which i do no see ;-)

[Archana Kadam]

@livius
recv_pkg_len = recv_pkg[1] is this declaration correct in gateway code.

[jcaron]

@archana-kadam Please share the actual code you are using, no sense trying to guess what you have in your code. In the gateway code as posted in the docs, I don't think it's possible to get that error on that line with the test just before it...

Please make sure your code is properly formatted when you post it (add ``` on a line before and after the code).

@jcaron
I am attaching the file of gateway and node code please go through the file and please check update me as soon as possible. Your help will be appreciable.1_1522300805718_Node.py 0_1522300805717_Gateway.py

[Archana Kadam]

@jcaron
We tried the gateway code and node code provided in the documentation, we connected one gateway and one node. The communication between two boards has been created but we are enable to fetch the device number,package etc. So please update for this solution.

Thank you

[Archana Kadam]

@jcaron
Please update to soon. Your help will be appreciable.

Thank You

[Archana Kadam]

Please reply as soon as possible, waiting for your solution. Your help will be appreciable.

Thank you

@administrators
Which type of LoRa module your are using in pycom board. Can you please share us the schematic of Fipy development module.

Thank you

Have you had a look at my forum thread?
https://forum.pycom.io/topic/2908/creating-a-json-structure-for-pysense/9

This has me reading all PySense values, packing them into a bytearray for LoRa transmission and the unpacking them at the other end with some simple JavaScript on a Node-red environment.
