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

  • @Colateral
    I also wait for this but still do not know how to work with it
    STA work but AP not able to connect

  • If Wipy WLAN is configured simply as STA-AP ... the ftp is not working.

    from network import WLAN
    wlan = WLAN(mode=WLAN.STA_AP, ssid='Cola', auth=(WLAN.WPA2, 'abc12345678'))
    wlan.ifconfig(id=1, config=(', '', '', ''))

    connect to 'Cola'
    and ftp(with micro/python) is connecting on but fails on root dir (/flash)

  • @johncaipa, for sure, I'll work on an example for US frequencies and will add to the same repo where the other are. We'll do our best to get it done today or tomorrow.


  • @robert-hh, no worries, our only focus from today onwards is code maturing and doing the migration to the MicroPython migration. We'll also update our own repo as we were sorting out the way to publish Sigfox libraries.

  • @daniel Hello Daniel, I do not want to impose any kind of pressure on you, since you are doing a great work in imroving the device, but at what time do you plan the next update of the github repository with the micropython files?

  • Someone can help me with an example of how to use it on US or AU frequencies, I still can not do it on my own. Thanks

  • Thanks for the thumbs up!! :-)

  • @daniel Really nice update! NanoGateway and OTAA node works like a charm! Thank you Pycom Dev Team! :)

  • @daniel Thanks! It works!

  • @constantinos please try playing with the public argument in the constructor:

    Before the last 2 releases the default of True for the public sync word was not being honoured, and now it is. Set this value to False and that will most likely make the LoPy work with the RFM95 again.

  • Daniel,

    I lost the functionality of receiving messages from RFM95. It was working with firmware version 1.2.2 and now is lost.

    I just receive nothing at all now.

  • Pybytes Beta

    This is really fantastic news. I immediately uploaded the code to by LoPy.
    TTN Dashboards shows gateway is connected!
    Now I have to test to send messages to it with my other LoPy.

  • Very good news, we were expecting this !. Congratulations to the entire Pycom team.

  • @daniel Congratulations for you and the whole team! I've just upgraded to 1.6.7.b1, and tried the examples (NanoGateway and OTAA node) and... it works like a charm! I'm currently sending my room temperature (from a DS18B20 sensor) on TTN using these examples!

    For now, there is no TTN gateway at range at home, I have to move away from my home to find some signal. The possibility to create a "dev" nano-gateway that connects to TTN allows me to work on my projects from home, this is wonderful!

  • @jmarcelino thanks for the suggestion! I'll include that on the next nano-gateway release along with the other planned improvements :-)

  • @zmrzli the answer from @robert-hh is correct, it just works like that, but some devices take a while to scan for networks again or to update the ssid if the MAC address is the same. Try switching the WiFi of your iPhone on and off as suggested.


  • Hello @zmrzli,
    no idea what you did, but this sequence works for me:
    from network import WLAN

    wl = WLAN(AP)
    wl.init(mode=wl.AP, ssid="My_lopy", auth=(wl.WPA2, "This is a Test"))

    It takes a while before the change gets visible on the other devices, if these do not scan the networks frequently. Sometimes on cycling Wifi Off/On helps.

  • I am not sure why there is no response to this problem... previously posted, so here it is again.
    Am I the only trying to do this, or I am missing something obvious...?

    Is is possible to change SSID of wipi in AP mode?


    import machine
    import os
    import pycom


    uart = machine.UART(0, 115200) # disable these two lines if you don't want serial access

    from network import WLAN
    wl = WLAN()

    #trying to change AP properties:

    original_ssid = "MyNode"

    original_auth = (3,'bewell')

    wl.init(mode=WLAN.AP, ssid=original_ssid, auth=original_auth, channel=6, antenna=WLAN.INT_ANT)

    Does not change SSID visible on my iphone.
    It remains wipy-wlan-xxx
    Am I doing something wrong?

    Or SSID is hardcoded regardless of what says in documentation:

    Get or set the SSID when in AP mode.

  • Wow, great development! :-) This is A LOT better than my simple gateway code, well done Pycom team. This will now run permanently on one of my LoPys.

    Just a suggestion, there is a convention for Gateway IDs on TTN, they're usually the first 3 bytes of MAC address + FFFE + last 3 bytes of MAC address, so I added the following to

    import machine
    import binascii
    CONVENTIONAL_EUI = binascii.hexlify(machine.unique_id()).upper()
    # Set Gateway ID to the first 3 bytes of MAC address + 'FFFE' +  last 3 bytes of MAC address 
    # Alternatively uncomment and change this to your fixed Gateway EUI
    # GATEWAY_ID = '11aa334455bb7788'

  • @this-wiederkehr sorry, we haven't pushed the latest docs. There's a new method called stats, try:


    Which returns a namedtuple that contais the rssi, snr and other usefult data (from the last received packet).
