Hi @xefiji,
Your example is about LoRa point-to-point connections while this forum is about The Things Network (TTN) and LoRaWAN. With LoRaWAN nodes send messages to gateways which forward the messages to a central TTN backend server where they are picked up by user applications.
LoRaWAN does not support point-to-point connections and latter are not supported on the forum.
Thank you @bluejedi ok iāll try somewhere more appropriate for my use case (SO or Github) .
Hi guys,
Does anyone made a platformio port of https://github.com/kizniche/ttgo-tbeam-ttn-tracker ? Or does anyone know where to find it ?
Iām trying it myself but Iām getting stucked in converting issues.
And why should I re-invent it when somebody else already has 
Thanks
There are not so many changes in schematics / parts of the most recent T-Beam v1.1 revision for paying attention to.
However, the PCB layout has been altered a little bit. Which makes older 3D enclosure for v1.0 to be no longer appropriate for v1.1
This is an illustration of all the āexteriorā updates:
More details are available at this Thingiverse page .
I have a question regarding the frame counter check. Do I have to reset the counter every time I restart the t-beam? I am using hottimucs mapper.
Is this the frame counter?
LilyGO direct AliExpress store has started to process orders on a new variant of the T-Beam board with most recent Semtech SX1262 LoRa radio IC:
It is expected to be Semtech āLoRa Spaceā friendly in:
This improved T-Beam is known to work nicely with TTN by means of port of BASICMAC (successor of LMIC) LoRaWAN library for Arduino IDE.
I need help in case of OTAA. It just stays on EV_JOINING. I am using the hottimuc mapper. It works with ABP, though. What could that be? The frame counter looks a bit odd, too. Do you still need to reset frame counter when using OTAA? When I choose SF8 it says āOP_TXRXPEND, not sendingā, what does that mean?
Sorry for the black bar on the top, thatās due to the refresh rate of the display.
In the LilyGO Aliexpress store I noticed a new offering for the T-Beam V1.1 (8th August 2020).
I see now that there is a variant of the V1.1 board with an SX1262 radio module. 
Iām facing exactly the same issue with this repo:
Iāve edited the configuration to use the European frequency and i can see the join request on my gateway with the right device code app etc etc and i saw that the network server accept the join request but it seems nothing received back by my device.
I canāt succeed in running the Paxcounter for ttgo t-beam v1.1. I donāt understand how to actually setup the files. Is there any other detailed example ? Could you please provide a mini tutorial with steps ? thanks in advance
@Amedee I donāt understand what have you highlighted in that link? How should I get my EUI for ttgo T-beam instead of generating it in the TTN? Thanks.
I managed to upload the default code. Steps are:
platformio_orig.ini file (or create new one) with the platformio.ini name.src/paxcounter_orig.conf to src/paxcounter.conf or create new onesrc/lmic_config.h as you needsrc/loraconf.h (after the src/loraconf_sample.h)src/ota.conf
The code was successfully loaded on my board, even though I still canāt manage to actually write my own code. I would like connect a BM sensor for temperature and send data trough TTN. I did something similar with cubecell but it was easier. I would like some help regarding how to write code on this board (now that I have the paxcounter project running, what should I do next?).
Do you have a working Visual Studio Code with PlatformIO?
The Basic Steps after the Download of the project as Zip file are:
Unpacking the Zipfile
Rename or copy platformio_orig.ini to platformio.ini
Open the directory with VS Code
Edit the board section in platformio.ini comment out generic with a ; in front
and remove the ; in fornt of ;halfile = ttgobeam10.h
check /src/hal/ttgobeam10.h if settings
check and edit /src/lmic_config.h if your region is active
Rename or copy loraconf_sample.h to loraconf.h
Edit OTAA or ABP Keys with the keys from the TTN Console
Rename or copy ota_sample.conf to ota.conf (There is no need to edit the file, it is needed to get the project compiled)
Rename or copy paxcounter_orig.conf to paxcounter.conf and edit settings for your needs.
Save all edited files (by closing the tabs)
Change to PIO with the āBugā symbole on the most lefthand row -> Press Clean-> Press āUpload and Monitor Allā
Thank you, Iāve successfully uploaded the project onto the ttgo t-beam v1.0 board. The problem is that I donāt quite understand how I have to modify (and where , and which is the API) in order to attach a sensor to the board and start sending packages to the TTN. I would be glad if you could help me with this problem also. Thanks and Happy Holidays!
Last answer was to slow.
But you manged it by reading the manual.
Copy the section for your BME Sensor from /src/hal/generic.h in your ttgobeam10.h and uncomment the ā#defineā lines
So basically in my main.cpp the only header I am using is the ttgobeam10.h?
P.S What if I have a BMP sensor ?
There is no need to edit the main.cpp to get the BME/BMP sensors running.
I canāt succed in using the ttn-otaa example. With COMPILE_REGRESSION_TEST defined, I get errors like LMIC_getSessionKeys' was not declared in this scope and also EV_TXSTART, EV_TXCANCELED etc. What should I do ? thanks
Check that you are using the latest stable versions of Arduino IDE (or PlatformIO), that the ESP32 support package is updated to the latest version, same for MCCI LMIC library and take care that you use the examples included with that MCCI LMIC library and not one from a different version or from a different library.
Your errors indicate a possible mismatch between example and LMIC library.
I donāt know how to do this. The thing that I tried was to follow this tutorial for installing ESP32 by Espressif Systems (I think the problem comes from this , because in rest I have all versions up to date, and a single LMIC-master-library installed in my /Arduino/libraries).
