But, If I want to use a openwrt I have two folders:
Both has differents app, but if I want to run the concentrator, they started but I dont have connection to ttn servers. I did run the follow commands:
1.- I change global_conf.json to US frequency 915Hz and ttn servers.
2.-Run (i modify eth0.2 for the wan connection) ./update_gwid.sh local_conf.json
3.- I reset pin on folder: /usr/bin/lora/
4.-start concentrator on folder /usr/bin/packet_forwarder
and run ./lora_pkt_fwd
5.- The Concentrator start but I dont have any ACK:
I made a duplicate sd (and some backups) and stopped the Loriot gateway after booting the duplicate.
There was no uninstall.sh although they mentioned it.
I manually moved/renamed the /opt/lrt and rebooted.
The TTN gateway was easy to install with the link you provided.
I can swap the sd cards now to choose the network Loriot or TTN.
We made same testing but pls note we put the antenna in vertical position on table. The performance should be fine.pls see the snapscreen! Can we resend an antenna to you for testing again if you like?
hello! I was working with this model of RAK 811 LoRa enabled chip and, tried to use this forum and the hackster one; neither had the information as i needed, so im going to try to put it clearly so everyone else can make the node work without all the hassle:
first of all you need to flash the correct firmware to the RAK811 board, this is the link where you can find all the software and the firmware to do this: https://github.com/RAKWireless/RAK811/tree/master/AT Firmware
then you shoud use an arduino MEGA if for some reason you can´t find one you can use software serial but be aware that you need to use it as a separate function to call it when necessary and for the software serial to be able to interrupt whatever the arduino is doing at the moment.
when pluging the board to the arduino bend all the pins in the right side( the one side that has the rx and tx) and then proceed to connect a jumper cable from the rx2 and tx2 of the mega(in my case i decided to use rx3 and tx3 due to space constrains on the device) or the pins that you defined as the software serial to the shield this way:
where tx3 is connected to tx pin and rx3 is connected to rx pin on the rak.
the jumpers on the board should be connected this way:
so the voltages on the arduino wont damage the shield and the commands sent by the arduino make it to the actual chip and not the serial monitor on the usb line of the arduino.
@audorva Well, that's not too easy to answer. If you got a good rssi (singal strength) but much noise (low snr), you won't receive anything. Same if you got no noise (good snr) but the signal is too low (bad rssi). You can look at the link budget for a hint.
