I get much errors durring compiling in plattform io #218

Open martinmmi opened 1 year ago

martinmmi commented 1 year ago

Hello :)

Iam martin from germany and i try to connect my ttgo v21 boards with the the things network. Unfortunately I get a lot of errors in platform io so I don't know how to start. :(

Here are my steps so far:

  1. New Project in plattform io
  2. Clone the "arduino_lorawan_esp32_example.ino" into the new projekt
  3. Install the following libs from the example via the internal plattform io lib installer:

MCCI Arduino Development Kit ADK 0.2.2 MCCI LoRaWAN LMIC library 4.1.1 MCCI Arduino LoRaWAN Library 0.9.2 LoRa_Serialization 3.2.1

  1. Added the files secrets.h and LoraMessage.h according to the description in the source code / git.

  2. include in each file

  3. Try to compile.

Here a screenshot from the errors: errors

Here a screenshot from the secrets.h and loramessage.h: loramessageh

secretsh

Can you give me a small support via discord?

Here is the repo, what i opened for this project: https://github.com/martinmmi/ttn_mqtt

Well, I'm afraid I cannot provide this kind of support! And normally I reject any questions concerning PlatformIO, because I'm only using the Arduino IDE - but today is your lucky day!

Please remove your src/LoraMessage.h. This hides a file with the same name provided by the library LoraSerialization. The correct board definition is provided by some magic from platformio.ini.

Then change platformio.ini as follows:

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

    ; -D CFG_in866=1
    ; -D CFG_kr920=1
    ; -D CFG_us915=1

The first thing was that the SPI library was missing - it's built in with the Arduino IDE, but here it has to be provided explicitly.

Then we have some LMIC specific stuff - parts of it more or less easy to understand (defines for the radio module and the LoRaWAN region), other parts of it... not so obvious (proudly copied from here: https://github.com/lnlp/LMIC-node/blob/main/platformio.ini).

Finally we have two warnings which have to be fixed:

  1. Warning: main.cpp: no return statement in function returning non-void [-Wreturn-type] Fix: please change

    bool uplinkRequest(void) {
    m_fUplinkRequest = true;
};

    to

    void uplinkRequest(void) {
    m_fUplinkRequest = true;
};

  2. Warning: ttn_mqtt/.pio/libdeps/ttgo-lora32-v21/MCCI Arduino LoRaWAN Library/src/Arduino_LoRaWAN.h: control reaches end of non-void function [-Wreturn-type] [Ln370, Col25] Please see mcci-catena/arduino-lorawan/pull/204

Good luck!

BTW: You can safely ignore this warning: #warning "You must replace the values marked FILLMEIN with real values from the TTN control panel!" [-Wcpp]

Omg. Thank you so much! Seems like it's working!!! itworks

martinmmi commented 1 year ago

One more question:

How can I connect to the follow gateway id (its only 500m left from my home): Gateway ID: oi-lej-gw01 How can i say that my device connect with this gateway? Or will it do this automatically?

And I have much authenification id's on ttn. Which one i have to use for appeui in the abp mode?

deveui[] = { 0x3D, 0xD4, 0x05, 0xD0, 0x7E, 0xD5, 0xB3, 0x70 }; LITTLE-ENDIAN appkey[] = { 0x20, 0xD9, 0xAB, 0x7A, 0xD7, 0x60, 0x4A, 0xC5, 0x6E, 0x6E, 0x3B, 0x35, 0x38, 0x92, 0x3F, 0xAB }; BIG-ENDIAN

appeui[] = NwkSKey ???

ttn

matthias-bs commented 1 year ago

Hi Martin,

I don't know if you can restrict the connection to a specific gateway. AFAIK, if a node is received by multiple gateways the network handles it in the proper way (e.g. avoiding transmission of duplicate payload messages)

Regarding the IDs, have a look at https://www.thethingsindustries.com/docs/reference/glossary/ or in the TTN console, select your device, go to the tab "General settings" and hover over the help in the sections "Network layer" and "Application layer". The "S" in some of the IDs stands for "secret" - you should not expose those to the rest of the world...

Normally (unless to have hardware/software restrictions which prevent this, which is not the case with ESP32 and LMIC-based SW)), you should use OTAA instead of APB. You can find an explanation why on the excellent TTN website as well.

Cheers Matthias

matthias-bs commented 1 year ago

BTW: You can at least use LoRaWAN specification 1.0.3. The regional parameters are selected automatically in this case. Not sure if a later version would also work...

martinmmi commented 1 year ago

Okay, thank you so much. It works! I coulded connect with the gateway oi-lej-gw01.

13:42:52 Forward join-accept message 13:42:51 Accept join-request

Is the example based on abp mode, or?

https://github.com/mcci-catena/arduino-lorawan/blob/master/examples/arduino_lorawan_esp32_example/arduino_lorawan_esp32_example.ino

When i like to try the otaa mode, i have to use this example, maybe? https://github.com/mcci-catena/arduino-lmic/tree/master/examples/ttn-otaa

Thanks so much!

matthias-bs commented 1 year ago

The ESP32 example uses. OTAA.

kadirozdinc commented 1 year ago

I try to make the sketch work but I got an error. I use ESP32 DOIT V1 dev board and HopeRF RFM96 868mhz Radio module. I made those changes mentioned above I could compile successfully but esp32 restarts itself continously.
