hi, I am new to OpenMQTTGateway and very impressed so far.
i use two boards of Lilygo Model: T3 V1.6.1 20210104,
I programed two boards with this repository:
as sender and receiver and worked correctly.
then i download openmqttgatway directly from web by lilygo-rtl_433 to the receiver borad and confige, it connect to wifi and mqtt broker correctly but i can not receive my flasher messages from another board, while openmqttgatway receive more than 10 lora sensor from around!
it is a view of mqtt explorer:
thank you for your quick answer.
my board is 433/470 MHZ, it means i can’t use this for LoRa Gateway?
I upload two environment ( ttgo-lora32-v1-868 and ttgo-lora32-v1-915) but no work correctly and i cannot connect to wifi and configure.
Thanks a lot, I uploaded ttgo lora32 v21 and OMG runed properly. I changed Frequency in WeBUI → LoRa config to 433 MHZ and saved then restarted the OMG.
I uploaded on another board LoRa Sender From this repository :
I have a similar situation, needing to use my LiLiGo LORA32 T3_V1.6.1 board as the LORA gateway to MQTT. There is another alternative I just found. It involved building the project in VS Code PlatformIO, but it seems to work for me. The hint I needed was in the (Option 3) Upload your configurations section of the Build page. What I did was:
Clone the Github repo
Change the branch to v1.6.0 (Really important! Wasted a few hours on failing builds in the default “development” branch)
Add my own liligo_lora_env.ini file to the top level directory
In that file, I have:
default_envs = ttgo-lora32-v1-433
extends = env:ttgo-lora32-v1-868
'-DZwebUI="WebUI"' ; enable WebUI as a default for all ESP32 builds ( the module only enables for ESP32 based builds )
You may need to tweak the LORA radio parameters other than SPREADING_FACTOR to match your transmitter. That happened to be the only one I needed to change to get everything working.
I also spend 3+ days to figure it out, I used also some sender github reps +gateway firmware was picked up based on this totorial:
with this board: LILYGO® TTGO LoRa32 V2.1_1.6 Version 433 - I see lot of neightbor sensors;
LILYGO® TTGO Meshtastic T-Beam V1.2 ESP32 LoRa Development Board 433MHz - with this I did not managed to get it work with firmware that is told to use in that YT video. ( [lilygo-rtl_433] lilygo-rtl_433 - ttgo-lora32-v21)
ttgo-lora32-v1 - it boots up, in web UI I see LOA settings, sat to 433… but in mqtt explored no RTL_433toMQTT, seems it does not receive anything, either issue with board or wrong firmware. But it works with Meshtastic (messhaes goes in/out on primary chennel).
also, noob question, any chance to add Meshtastic (device as sensor) to see it in OMG? I have only two boards, not sure does my T Beam works, maybe board issue as it does not appead as sensor.
Hi I would just like to help the case along, also in my own interest .
I use the same two boards of Lilygo Model: T3 V1.6.1 20210104, only the 868mhz edition. I programmed the two boards with the same repository as mohamad_saleh_Ebrahi and sending and receiving packages worked fine.
As suggested by 1technophile I tried ttgo-lora32-v1-868 (which seems to just be ttgo-lora32-v1 now) and it did not work on this board. Seems like the scripts are in constant development so:
Then tried ttgo-lora32-v21 which I could hook up to Wi-Fi and mqtt, so far so good.
Logging into the gateway and looking at the console it seems to receive the lora packages but there is still a fault:
E: LORA packet deserialization failed: InvalidInput, buffer capacity: 768
E: Empty JSON, not published
