How to add Dragino Lora/gps HAT to V3

End Devices (Nodes) Dragino
126

@Jeff-UK That was going to be my first question too.
@mauriceatkinson That snippet of the log file simply indicates the device hasn’t joined yet, it would have a devaddr if it had.

I would need to see ALL the log file for the session (get rid of previous stuff and start clean)

In the past, before I got my gateway back on V3, I had a similar problem. My transmissions were seen 11Km away but the replies well, probably bounced off some buildings and went into space. Fixed as soon as my gateway was back up and running.

My project is on hold for the moment - the local council are not the fastest at implementing anything so it’s been about 5 months since I last revisited this code and am a tad rusty.

@Jeff-UK the sensor and the ttn gateway are in adjoining rooms. The rssi is -51

@bnnorman see below the test.log

Most common reasons for nodes not joining, the RSSI is to high causing channel bleed and overloading the RX front-end. Move the node 10m to 15km from the gateway and preferably if the distance is short have a brick wall inbetween. RSSI need to be below -60 or so preferably.

129

@Johan_Scheepers thanks for info. The sensor was about 500m away from the gateway today and it was still not working. I brought it indoors to debug.

130

Look for RSSI values from -65 to -95, reality is -50 to -112 ‘should’ be ok but helps eliminate any uncertainty.

How is node configured/registered in TTN console - RX1 & Rx2 windows set the same both ends?

131

How are the gateway connected to the internet? If the latency is to high the downlink arrives after the node have stop listening for it.

I would check this to make sure it is acceptable.

132

my rak 7268v2 gateway is connected to my home router via ethernet. The internet speedtest shows 92mbps download and upload speed with ping time of 12ms. The internet looks good to me

Ref this entry …

2023-02-26 18:00:45,801 - saveCache - 495 - INFO - Saving MAC settings failed Object of type bytearray is not JSON serializable.

Something is corrupted here. this is raised by the json.dumps() call, I think.The cache contains the MAC settings for joining and caches the devaddr when joined. This hasn’t happened because of the corruption.

I’m guessing that something in your Dragino.toml file is causing this.

Ok, so in the file dragino/MAChandler.py at line 484 you will find the method saveCache(self). If you put a print statement as below and re attempt we should get an idea what is blowing it up.

def saveCache(self):
        """
        MAC commands received from TTN alter device behaviour
        """
        try:
            self.logger.info("Saving MAC settings")
            print("CACHE:",self.cache)   # <---------------- Add this line

``

Alternatively let us see your dragino.toml config file.

Is anybody using a decent replacement for the Dragino lora/gps hat for the pi? It is no longer available to buy so looking for something new.

136

I made one with just an RFM95 on a breadboard HAT - no GPS - it works. Check board_config.py for CS & DIOx pins. The DTOverlay determines the SPI pins IIRC

The wiring is simple, it’s just SPI but they chose BCOM pin 2 for the CS.

I made a KiCAD pcb design (not actual PCB) for a dragino with GPS. This will give you the pins.

Without GPS you only need RST,MOSI,MISO,SCK,DIO0,DIO1,DIO2,NSS

Not in Aus but Raspberry Pi LoRa/GPS HAT - RobotShop is expecting 868 versions in on 12th Sept. So ought to be available. They are being made by seedstudio.

I thought the sx127x would run at any frequency 100-1000mhz so I don’t know why they are sold as 868 maybe its just marketting.

RF components on the output side usually - 868 & 915 are generally close enough for a non-optimal board.

139

Uputronics have a board for both full size & zero formats:

Totally recommended.

I might buy one…next month…to investigate it.

I am seeing a reoccurrence of this issue again. Last time I changed the dragino board and the problem resolved itself. I have now changed out two dragino boards and the problem still occurs running the ./test.py command. Of course it could be two faulty boards but these were both new and working ok before suddenly stopped with this error.

any ideas much appreciated!!

I replied to this at least two weeks ago on a PM reply to your PM but I have not heard back. Have you fixed it.

For the benefit of other readers:-

Somewhere in your version of the code you are trying to put the RFM9x to sleep using mode 0 (Key Error: 0), which isn’t a LoRa sleep mode listed in Constants.py. It should be 0x81 (i.e. MODE.SLEEP is defined in Constants.py as 0x81 not 0x00).

MODE.lookup[mode])

Would then return a string and not fall over.

143

sorry I never saw your dm reply.

The workaround I used was to swap out the dragino board and this worked for a couple of days before the problem reappeared. I then swapped out the board for the orginal one and this worked again (and is still working).

I looked at the code in LoRa.py and see this section with MODE.lookup[mode]) but I dont see this defined as 0x00.

In Constant.py the MODE.SLEEP is defined as 0X80

So I suppose I cannot find what you are saying needs to be changed, what am I doing wrong?

    def set_mode(self, mode):
        """ Set the mode
        :param mode: Set the mode. Use constants.MODE class
        :return:    New mode
        """
        # the mode is backed up in self.mode
        if mode == self.mode:
            return mode
        if self.verbose:
            sys.stderr.write("Mode <- %s\n" % MODE.lookup[mode])
        self.mode = mode
        return self.spi.xfer([REG.LORA.OP_MODE | 0x80, mode])[1]
144

When writing to the SX127x mode register (0x01)

0x80 = Sleep
0x81 = STDBY (Idle)

145

This should mask the problem but it would be better to know where the code is getting a mode value of 0 from when it should be 0x80

sys.stderr.write("Mode <- %s\n" % MODE.lookup[mode | 0x80])

or we could try raising an exception which should give a traceback showing where the value of mode was set to zero.

 def set_mode(self, mode):
        """ Set the mode
        :param mode: Set the mode. Use constants.MODE class
        :return:    New mode
        """
        # the mode is backed up in self.mode
        if mode == self.mode:
            return mode

      if mode==0:
            raise Exception("Invalid mode value")

        if self.verbose:
            sys.stderr.write("Mode <- %s\n" % MODE.lookup[mode])
        self.mode = mode
        return self.spi.xfer([REG.LORA.OP_MODE | 0x80, mode])[1]

I find it hard to believe the Dragino RFM95’s are developing faults.
