Sure it is radio 
But it could be interesting to have an access to an historical of your received data associated to their timestamp…

Dragino+pi3 node transmission problems
Code for the Node repository we are using? I linked the repository in my previous post.
Instead of taking a screenshot of my code should I just post the code as text in the form?
Its just a simple python program. Same thing for the Weight sensor. But right now we are just using the RFID sensor until we are able to get everything deployed and verify that its a functioning system. Once that happens we will calibrate and begin reprogramming the weight sensor to start functioning.

Access to previous data in Payload format
Not what you’re asking, but the Storage Integration will keep the last data for 7 days. Setting up some server that uses the MQTT API and its own database will really make your life much easier though.

Dragino+pi3 node transmission problems
I’m not going to try to figure out what I need to look at, at https://github.com/dragino/rpi-lora-tranceiver …
And yes, for posting text see How do I format my forum post?

Connection with a end device don't work
yess, thank you ! 
Now my sensor is connected !
Now in my application data I receive only “Activation”, I d’ont receive some data (0 Frames up)
I don’t understand …
this is my android code : https://github.com/LucasMIRADEC/LoRa/blob/master/LoRaTTN
If somoene can help me…

I attached the entire code file but I am pretty sure this is the only part you need to see. Its the portion of the code where you can change what the payload is, set the freq, SF, and channel.

Dragino+pi3 node transmission problems
…so you’re still using some peer-to-peer bare LoRa software for the device?
You’ll need some LoRaWAN library for the device/node, in which you will also need to configure the device’s DevEUI, AppEUI and AppKey (for OTAA) or DevAddr, NwkSKey and AppSKey (for ABP).
Ah, you already wrote that:
This might help, but I’ve not used it: https://github.com/wklenk/lmic-rpi-lora-gps-hat
(Oh, you mentioned that one too 
Time to get away from the keyboard for me. So, yes: try that!)

Cheap and simple LoRa Node for schoolproject
For my educational nodes I selected a “simple” microprocessor like AVR processor that has good Arduino support and a Microchip rn2483 LoRaWAN module that has embedded stack. This is the Things Uno in my case who has antenna embedded. On top goes a custom made board.
The reason is that I want to eleminate risks and have the higest successrate.
I want to focus in class on my learning objectives and not on debugging nodes and lorawan stacks.
I would select non of them for my purpose.

Upgrade TTN Uno: RN2093 firmware
Hello,
I’m attempting to upgrade from Model: RN2903 Version: 0.9.5 to latest firmware following this guide: TTN Uno - RN2903 firmware upgrade
I created a new topic because that other one seems to deal mostly with Australian customizations. I’m trying to do a vanilla US firmware.
Here is where I’m at:
- I downloaded and opened https://github.com/SodaqMoja/RN2483FirmwareUpdater in Arduino IDE
- I added http://downloads.sodaq.net/package_sodaq_samd_index.json into Arduino IDE preferences
- I uncommented #define HEXFILE_RN2903_103
- When I try to compile I get this error regarding LORA_STREAM not being defined. I fixed that by doing #define LORA_STREAM Serial1 (no idea if that’s the right way to fix that).
- The second error I get is this:
exit status 1
'Uart' has not been declared
I don’t know how to fix that one.
Also, I have no idea if I’m picking the right firmware.
//#define HEXFILE_RN2903_098 I’m guessing this might be mine
//#define HEXFILE_RN2903_103 Or this one
//#define HEXFILE_RN2903_SA103 I’m guessing this is south america (I’m in Canada)
//#define HEXFILE_RN2903_AS923_105 I’m guessing this is Asia … not me
What does 098 and 103 mean? And how do I know which one is right for my particular TTN Uno?
On my Uno the chip says: “RN2903 16401MY”
On the box it shows model: TNN-003-915-1.0
Thank you,
Tomas

What is the lowest TX power you have measured using the RFM95W?
Got it. OK, so it’s normal for the unit to have only about 33% to 25% efficiency when transmitting?

Things Uno - Join not accepted: denied
I’m still working on the firmware upgrade … in the mean time I noticed something unexpected. When I booted my TTN uno this morning it does this
ttn.sendBytes(data, sizeof(data));
Sending: mac tx uncnf 1 01
Response is not OK: not_joined
Send command failed
I’m surprised because all day yesterday I did many reboots of it and it consistently did “Send command succeeded”. (I did have trouble receiving at the console, but at least it didn’t fail outright like now) It appears that I somehow lost registration. I tried rejoining, but I’m back to the join not accepted problem (and no - waiting it out doesn’t help, it doesn’t join even after 15 minutes). How does a node lose its joined status?

I would agree.
Those u.fl connected antennas are just about acceptable when used in a cased unit, but as is they wont last 5 minutes in a classroom environment.

What is the lowest TX power you have measured using the RFM95W?
Sure, and if you take a look at the datasheet for the SX127x you will find it agrees as well.

Helec LoRa 32 (V1)LoRaWAN Node
Hello, I’m starting to study IOT and I’m having a lot of difficulties on my first project, can anyone help me? I’ve been working on it for days. I do not know if the problem is in the gateway or in my source code.

Wifi/BLE Paxcounter Project with ESP32 boards
Paxcounter software relies on LMIC stack, and this expects a full LoRaWAN compliant 8ch gateway. Otherwise it won’t work, at least not with tweaks in LMIC stack.

Dragino+pi3 node transmission problems
Haha no worries. We are meeting tonight to work on it as a group, hopefully We are able to make some progress.

please format your post
we don’t like big chunks of copy/pasted code.
after you’ve cleaned up I will move your post to the right topic which is NOT dragino

Do you have a single channel gateway? If so, you will receive just a fraction of the packets, so be patient.
