Hello @binux I know this is a slightly old thread, but i wondered if you could perhaps share your code please? I am trying to do something similar - I would like to run two pytracks accelerometer at or as near the same time so I can record vibrations at two positions and unless trying to reset both at the same time I am unsure how to do so, I thought your code may help! Thanks

@dhblumenfeld1989 This cannot be the full script. At least a two lines are missing upfront, like: from network import WLAN wlan = WLAN(mode=WLAN.STA) And as a side note: The flash size you get with uos.getfree() is not relevant for memory errors. These are caused by RAM shortage. The size of free RAM is told by gc.mem_free(). And for all people trying to help it is useful to know the firmware version, which can be obtained by uos.uname().

@dylan The nano gateway uses the Semtech standard protocol which is uses UDP on port 1700, this is very different from your usual WiFi traffic and likely to be treated differently by your institution’s network policies. I guess you can ask them what is their policy for long running UDP sessions on port 1700 but in my experience, unless you are able to talk to core networking staff, you might not get a straight answer. Since UDP is a connectionless protocol the LoPy has no idea about the state of the connection either, by definition UDP is a “send packets and hope for the best” protocol. What you can do is point the nanogateway at another server, maybe some server you control outside of your institution network and have something listen on UDP/1700 there, can be as simple as Netcat: netcat -u -l 1700 Then wait that half an hour and see if the nanogateway messages still arrive there. Doing a packet capture (tcpdump) on port 1700 will probably help. If the packets stop arriving - the gateway will always send status packets even without LoRa traffic - you’ll know at least that you have a networking problem and nothing related to LoRa. You should also monitor the nano gateway, ideally over Serial to see if no error messages pop up.

@misterlisty if i understand corectly you talking about hostname? If yes, this is included in pull request created by @illysky https://github.com/pycom/pycom-micropython-sigfox/pull/100 And i suppose it will be avaiable in next firmware

Hello, I'm having a similar problem when trying to connect using EAP-PEAP. Has anyone gotten any results? Thank you.

Can you please run the following code after connecting to WiFi and post the output? import socket s = socket.socket() print(socket.getaddrinfo('time-a.nist.gov', 13)) s.connect(socket.getaddrinfo('time-a.nist.gov', 13)[0][-1]) s.read()

@soren said in Socket having to close and reopen: You close socket on server side then you must close it also on client side(it is closed already but..) Question is what problem do you have with the code? Is it working, if yes, do you ask if there is some better way?

@soren did you add code that affects the antenna switch? This is on GPIO16

Can you please check your firmware version? import os os.uname()

@robert-hh Number of concurrent transfers didn't make any difference. But the command line seem to work, and more importantly for me, it works from python with ftplib. I'll just stop using filezilla...

@this.wiederkehr Thanks, I will try that later tonight.

@reader-uk said in VLC Radio - IP remote control via Wipy 2.0: Originally I tried keeping this socket open and forced open. This was problematic and found its just as quick and efficient (and correct?) to open the socket, send command then close the socket. If it work then this should not be modified ;-) You can try to leave it open e.g. for 10 minutes and close if no command to send. Something like session timeout. Nice project :)

you have to restore your all wifi password credentials before resetting them, always chose unique password so that it could not be decrypted easily.

@RobTuDelft It's proprietary. I am writing raw HTTP data to TCP socket and then reading and decoding POST data (JSON).

Android and WiPy I' m working with this app from 2016 without problems. Remarks!! The used Android apps that I am using from the 2016 are the one that I find when I faced the same question that you have. Install(*) from Google Play Store the Mocha Telnet free application to open a micropython REPL session. To load drivers on WiPy boards, install AndFTP ( in my case) . Connect to WiFi WiPy network using www.wipy.io as password. In order to get the Python REPL, open MochaTelnet and from the menu select Telnet Settings and enter the IP 192.168.1.1 ( for WiPy 1.0) or IP 192.168.4.1 ( for WiPy 2.0 and LoPy) and the Telnet port number 23. Now return to main menu of Mocha Telnet an select Connect and at the login prompt in telnet terminal enter micro and at password prompt enter python. That is all. Federico Monaldi -July 10 2016

@chrisi yes, you can use the USB port (as a serial port) and have access to the REPL or to update files using Atom/Pymkr for instance. An alternative would be to include code which enables Wi-Fi on some specific event, such as a press of the button on the expansion board or Pysense.

Even with an External Antenna the BLE seems to have quite some problems. Sometimes it doesnt find anyhting at all.
