Hi. I have problems initializing the module “DollaTek LORA32 433Mhz ESP32 Sx1278”. It is a clone of the TGO LoRa32 SX1276 / 78 module. I cannot initialize it with the library <RadioLib.h>. There are problems with the pins. However, I can initialize it with the <Lora.h <library, and I can send and receive packages. The problem is that <Lora.h> does not use pins D0O1 and D0O2, it only uses it like this:

//define the pins used by the LoRa transceiver module
#define SCK 5
#define MISO 19
#define MOSI 27
#define SS 18
#define RST 14
#define DIO0 26
#define BAND 433E6
En el void Loop()
SPI.begin(SCK, MISO, MOSI, SS);
//setup LoRa transceiver module
LoRa.setPins(SS, RST, DIO0);

With this configuration the module works and starts perfectly with lora.h, BUT I NEED TO USE <RadioLib.h>

// SX1278 has the following connections:
// NSS pin: 18
// DIO0 pin: 26????
// DIO1 pin: ¿??
SX1278 lora = new Module(18, 26,?);

With this setting of <RadioLib.h> I cannot initialize the module.

I need help to initialize the module with the <RadioLib.h> library and be able to send and receive packages.
Can somebody help me?

make a custom case to hold all the motherboards of all the playstation consoles. ps1/ps2/ps3 and ps4. one box, all original hardware.

nice overview, wondering what kind of power consumption you're getting with LoRa and GPS enabled. Thinking of using these for light industrial use , and wondering if using the ESP32 deepSleep and waking every 1 hr the 18650 would last a reasonable time?

URBN CTRL

You get approx 24h use time from one battery charge. Solar or usb extends the use time significantly

Great video. Thumbs up and thanks for the reference to the new board.

One recurring issue though is that a lot of the antennas that are out there are actually not even close to being tuned for the band that they are supposed to operate on. I wonder how well the antennas on those boards really work at 915MHz? Of course your testing indicates that they are at least reasonably usable, but it's possible and probably even likely that there is a lot to be gained with a well matched antenna...

Proto G Engineering

I may end up trying some directional antennas.

Since it has a GPS, you can use the transmitter to send its GPS position, and use the receiver to calculate the distance between the received position and the receiver's GPS position.

V Ng I had thought about that. Maybe I’ll use the haversine formula in the code.

Just discovered your channel because ESP32 retweeted one of your tweets. I really like your setup.. very pleasing for the eyes. Your bench is very well lit. No camera shake, etc. Keep up!

Thank for your video and code.
Which IDE did you use to compile the code?
I tried the Arduino IDE with EPS32 addition to compile the GPS code and got errors

Thank you Gary

Marcelo Cheves

Thanks for the overview man, do you know how many free pins left on the esp32 for I/O use? thanks.

Nikola Balint

Hi, does this firmware works on version v.1.1 of boards? And can you change transmit power?

Hey, i'm using the ttgo t-beam board and i wanted to ask u somethings. How can i contact you? I've tried to message u on instagram though

Claudio Barca

Can I connect this board with a GPRS module to send data via HTTP (es. Thingspeak) the LORA received data ? If yes what module can be use ? Thanks

just a heads up the display pin outs from the one I got have ground and vcc backward

This is a cool project, links for the boards and screens?

Thanks, I just added it above in the pinned comment.

hello. When I try to install in to Arduino i'm getting an error Specified folder/zip file does not contain a valid library. Please help

Ihsan Amir

can anybody suggest for me, which frequency should i bought for using in south east asia country such as Malaysia?

jonathon triplett

what core are your using as i'm trying the gps.ino and getting uart serial errors i'm using the t-beam board from https://dl.espressif.com/dl/package_esp32_index.json 1.02 version and having issues running the default sketches i'm just trying to get the basic gps to display on serial and not having much luck:( getting "core\core.a(HardwareSerial.cpp.o):(.bss.Serial1+0x0): multiple definition of `Serial1'" which tells me that some thing is screwed up in my core files"

Did you try to go into sleep mode and low power consumption on GPS?

Haluk YILMAZ

how you get higher rssi?

Thom D'Auria

How do you have your iFixit kit set up to stick or hang on your bench rack like that? I was just thinking about trying something similar yesterday and happened to stumble across this video

I’ve been trying to figure out for like a half hour now what the hell the application for this would be other than a regular esp32

Terry Phan

Gps tracker over LoRawan is one of them.

can it connect to flow sensor ? sf402

Abu al-Sous

Good job
Thx man

Proto G Engineering

Thank you!

XenoContact

Looks fancy but what it is this good for?

Proto G Engineering

Yes, Team Black Sheep Crossfire uses LoRa for longe range RC flying.

XenoContact

Oh I see, now that sounds very practical ! Would the radio transceiver response time allow for it to accurately drive an RC plane over long range(>20km) ?

Proto G Engineering

It is a microcontroller with WiFi, Bluetooth, GPS and a long range radio transceiver. There are countless applications for something like this. Sensor networks, robot controllers, gps locator beacons, and so on.

YouTube’s Andreas Spiess got 200km on his with a proper set of the little antennas. Sounds like yours aren’t the right ones.

Proto G Engineering

6y↑9

His videos are great but that was direct line of sight and a world record that he broke by carefully choosing the two highly elevated points. He also had to use the SF12 reduced data rate of 250bits/s to accomplish that range. Depending on your application, that may not be acceptable. The example from the video is using the default data rate of 11,000bit/s which is a lot more data and the default transmitter power. The SF12 he used is also a much longer transmitted pulse than the default SF7 which will give you better range at the expense of max payload. You could definitely use better antennas than this but there are a lot of options for improving range through software. You can adjust TxPower, Spreading Factor, and Signal Bandwidth as well as other configurable settings.

Could you at least show how to program it....

Christopher cobb

I have a question I purchased the ttgo I soder every thing then i connect the antenna and power it on red light blinks but the screen is not powering on do you have any advice

crazymohawk86

Where exactly did you solder the display

mountassir Boumazoued

When i burne the code l lost wifi and bluetooth you have any idea bro

should of made them both rx and tx and put a kb on there you go, now try again and do it right this time....

you don't really have how to on instructables site. all you have is clock setup but not exactly how you accomplished the packet count. could you share that please ?
