Apart from moving the node, did you change the RX2 settings to the correct ones as well?

LoRa Mac Node - OTAA
Hi, your code works with ABP and does not work on OTAA because downlink fails because the your implementation of RTC is not good.
let’s see if i can help you. but i am sure https://github.com/Lora-net/LoRaMac-node/issues/588 is not a good place.
can you publish your code on github so i can review it?

Can Australian users agree on using a single frequency plan?
Perhaps we should take this offline however I would have thought Toowoomba, with access to all those surrounding peaks, would have been easy to cover with a few strategically places gateways on peaks. In such a scenario I would not have expected power to be an issue assuming the aerials are high enough above the ground to cover line-of-sight limitations.

Can Australian users agree on using a single frequency plan?
Actually yes Toowoomba is ok, we now have about 4-5 gateways in a small city.
I also have gateways in Goondiwindi, St George, Dalby, Muckadilla (outside Roma), Felton and just north of Toowoomba where the range will be determine how many users (farmers) we can include in demonstration trials.
cheers

No lower RSSI than -121 dBm possible in TTN?
How meaningful are the absolute sensitivity figures? Looking at
doesn’t this mean that if the environment my antenna is in has a noise floor around -100dB then the best I can expect is to receive a packet at -120dB RSSI? Whether the receiver has -137dB sensitivity doesn’t really enter the equation, does it.
Now if I could eliminate the noise by turning off some gear, say, and the noise floor drops to -120dB, then I wouldn’t be able to get packets at -140dB RSSI because the internal receiver noise and thus sensitivity is the limiting factor.
Aside from the fact that I’m using a bit idealized numbers that don’t take fading and stuff like that into account, am I on the right track?

BSFrance Lora32u4 stuck in sleep mode
Did you tried to stop the ModemManager service? It takes the serial port on boot. I had to switch it off as udev rules doesn’t work anymore.

No lower RSSI than -121 dBm possible in TTN?
Well, the receiver will typically report a no signal RSSI of between -100 and -105dBm, so at -20dB SNR you would expect the real sensitivity to be -125dBm or so.
I have never seen the receiver report noise of much less than -105dBm, even on remote hiilsides where quite deliberatly I carried out link testing with no electronic devices within a couple of kms, phone off, watch left behind etc.
I wrote this up in a report in 2015, a 40km hilltop to hilltop test, you can caculate the signal strength you are actually getting (because you know the antennas and distance) and by noting the transmit power at which transmissions fail, the report is here;
Semtech LoRa Transceivers – a KISS approach to Long Range Data Telemetry - January 2015
There is this comment on page 6;
“One anomaly that was clear from the results of Howie’s link budget calculation was that the signal strength of a 2mW transmitter at 40km calculated as -114dBm”
This was at SF8, so -10db SNR the comms are failing at -114dBm and not as the datasheet might suggest at -131dBm.

Finished Opensource Raspberry Pi Gateway Hat (SX1301/8 base)
Hi @will3509111,
I’m very happy with my gateway so far. The only problem is that it seems to get halted from time to time. I don’t know if it’s software issue. But it seems so. I reboot the packet forwarder and everything goes back to normal.
Do you have any experience about this?
Best regards,

Beer fermentation bubble counter: Heltec ESP32 Node-Red Thingsboard
Finally I got it to work! So great. Since i do not have internet access in the cellar and I wanted to count the bubbles created by my fermenting beer in order to know when its finished, I thought why not use the Things Network.
The setup is an heltec node with lmic sending to ttn. from there an http integration to my raspberry with node-red and from there an mqtt request to the Thingsboard running on the same device.
Really great stuff…
Here the prototype Sensor on the air-lock of the fermenter
and the dashboard in TB
The beer just started to produce carbon dioxid!!!
