Hi,
I think that, as described in the error, the problem is that the version of SSL is not supported by SSLClient; try to check the server security settings.

Hi Edge,
to show the frequency as you need, you must put one of these define before the library include.

#define FREQUENCY_868
#include "LoRa_E32.h"

Hi Sachi,
try to post your code so we can try to help you.

Hi Adi,

I don’t think it’s possible for the E22 to communicate with the E32 directly. They use different chips and have different cryptographic systems, which makes them incompatible for direct communication.

Best,
Renzo

Hi Adam,
You are right. The C1 is correct. It is also in the library. I verified that but also checked the other set that must be respected; if you receive that message, you have something wrong or some noise with the device setting. But if it works for the other operation, we will never discover what it is :D.

Ahh! Yes, I already found that some models of E220 have this “issue,” but they’re working correctly.
Sometimes, there is a power supply problem. In your case, it’s more rare, but you can ignore that response.

Hi Adam,
If it’s well connected, there are two other options:

• the power supply is not sufficient;
• the device is broken.

Try to use an external power supply for the module.

[Renzo Mischianti]

Ahh! perfect!
I am waiting for your news.
Bye Renzo

[Renzo Mischianti]

Ahh, wait, you use uart directly to send messages.
If I remember, I applied encoding in the library to prevent problems with not-in-range characters.
Use the library.

No, no, the Arduino esp8266 core.
probably the problem is that you don’t connect the AUX pin, and the waiting time is too long.
I’m going to add some tricks to prevent the brownout.

The structure can’t be the same if you read the first 3 bytes.

Check the last sketch in the link I posted before.

[Renzo Mischianti]

Aaah, no, wait, you read the first 3 bytes, then you try to reread the first 3 bytes again.
You must create a structure for the remaining data.

Check this article that explains how to manage the initial message.

[Renzo Mischianti]

But do you use the same MCU for the sender and receiver?

[Renzo Mischianti]

Hi,
ahh! Yes, the Terminator character.
It’s strange. Try to add this.

#pragma pack(push, 1)
struct LoRaNavData {
    char type[3];
    uint8_t dev_id;
    int32_t latitude;
    int32_t longitude;
    int32_t altitude;
    uint8_t crc8;
};
#pragma pack(pop)

Bye RM

[Renzo Mischianti]

Hi Poe,
try to pass

char type[3] = "NDX";

and give us feedback.
Bye Renzo
