No supported Arduino maybe.
Faulty device.
Device not wired correctly or soldering issue as described by the original poster.
Did you also try the ‘MCCI LoRaWAN LMIC’ library ?

I tried both with Arduino Uno and Nano Every and I get the sane error. I’ve tested MCCI LoRaWAN LMIC, too. Beside the oslmic.c:53 error in the serial monitor, I get a pinmap error in the compiler. Wiring is ok, so I guess I have to accept that it’s a soldering problem, due to my terrible soldering skills. I’ll post some pics of that.
Your Gnd joint looks like it could be a dry joint.
I’d touch each of them up looking to remove the excess solder and make sure it flows like a liquid. The soldering iron tip can not transfer any heat by itself, there must be a small amount of solder on it to do that for you. But not so much that you can start sculpting with it.
I think you’ll see it’s a warning about you having to define the pin map, not an error.
I’d stick with the Nano Every - far more room for both program and variables.
You don’t need to test MCCI LMIC, it definitely works (I was coding on it most of the weekend), you just have to tell it which pins are being used for NSS, DIO0 and DIO1. Once you’ve got that going, you can focus on the EUI’s & AppKey.
With the appropriate 5V to 3.3V Logic level conversion circuits I presume.
That device does not look like any of the Hope RFM95s I have seen. Hope normally have a different marking on the RF chip they use RF95.
I would alse be very cautious wiring LoRa modules up like that, if the antenna wire becomes disconnected when you attempt to transmit it could let the devices magic smoke out.

Thank you. I’ll proceed with the soldering tips you gave me, trying to fix it. And then try again with LMIC. I’ll update you. (By the way, I’m using a “single channel” Raspberry Pi 4 Lora Gateway, I saw in the forum that it’s not a good idea)
Eeeehm, nope. I am not using a logic level converter… I saw video on youtube of people not using it… By the way, I also have a Hope LoRa module, but I think I’ve damaged it.
So not only, zapping 3.3V module with 5V and solder bridges but also …
We don’t say it’s not a good idea, we say they should not be used due to the disruption to the network. And you have to alter LMIC to be able to cope with a SPCF which isn’t trivial.
Please disconnect immediately and read: Single Channel Packet Forwarders (SCPF) are obsolete and not supported
If you want to make some progress, get a TTIG for a gateway and buy a board supported by LMIC-node. I’d normally recommend the Adafruit Feather M0 with RFM95 but in this instance, as it requires some delicate soldering, maybe best to pick something else. 
Thanks for your rapid answer and kind suggestions! Do you think I still can make it with Arduino Nano Every, 3.3 to 5 V logic level converter and a Hope module?
I’ve a test device with a Nano Every and I have my own PCB with an ATmega4808 + RFM95 on it, it works fine with LMIC once you know LMIC.
You may want to use a breadboard & jumper cables until you’ve refined your soldering technique.
You still need a proper gateway.
I have the same problem with Dragino Lora Shield + Arduino Uno.
When I use your program, I get only this.
I am not told weather the lora device is found or not.
Any advice for me?
There are no writes to the LoRa device, something strange there.
Look at the code, It has to print found or not found;
if (begin(NSS))
{
Serial.println(F("LoRa Device found"));
}
else
{
Serial.println(F("No device responding"));
}
Which TTN library have you tried ?
An additional comment: Some of the registers are not what the should be, so it looks like there are read problems over the SPI bus.
As per the program notes the startup should be:
2_Register_Test Starting
LoRa Device found
Device version 0x12
Frequency at Start 434000000
Registers at Start
Reg 0 1 2 3 4 5 6 7 8 9 A B C D E F
0x00 00 09 1A 0B 00 52 6C 80 00 4F 09 2B 20 08 02 0A
etc.

Thanks for the reply, I think I purchased a faulty dragino lora shield. Even the light on the shield was not turning one, once it was connected to power.
I think it was a faulty one.
Good morning,
I am using an Arduino Mega 2560 board with a LoRa Shield RFM95W radio module. However I use LMIC to send my data to a Dragino LPS8N gateway.
And when I upload my program to the Arduino board nothing happens and I get the error displayed on the serial monitor:

Help me please.

What does it say on this line of the code?
Sorry, my screen reader can’t cope with images and neither can the forum. Please post text as text formatted using the </> tool. But don’t worry, I already know what’s on that line, I was wondering if you did.
But as, like others before you, I don’t see any thoughts on what it might mean.
Ok I will put the code using the </> tool. No I don’t know what exactly I’m a beginner on LMIC.
Do you have a solution for this problem

The entire file, really?
And text posted as text isn’t an option, it’s helping with the forum search, which you could try …
As well as reviewing the README relating to radio cfg as implied by the lines around 689 …
You could just paste the few lines concerned in stead of the entire file…
Can you use search? This isn’t the first time a question has been asked about this error. The last time was less than a week ago… also googling what an assert is used for might enlighten you what is wrong.
Hint, controller seems not get the right result from the rfm module. Are you pin mappings correct??
Sorry I thought you asked for the whole file.
I’m a debutant here.It’s my firts time on forums.
