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.

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.
Bye Renzo

[Renzo Mischianti]

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.

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.

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)

Hi Poe,
try to pass

char type[3] = "NDX";

and give us feedback.

Hi Marco,
I can’t reproduce your issue; for me, the library works correctly.

What version of core do you use?

Bye Renzo

[Renzo Mischianti]

Hi William,
I write to you by EMail.
Thanks Renzo

[Renzo Mischianti]

Hi Peter,
I have the same error when I do wrong wiring or power supply problem,
Can you verify this?
Bye Renzo

[Renzo Mischianti]

Hi William,
the project It’s interesting, would you like to publish an article about that?
Bye RM

[Renzo Mischianti]

Hi Marco,
Normally, problems like this one are generated by a low power supply to the module or a problem with the M0 M1 wiring.
Check It and retry.
Bye Renzo

Hi Anabel,
If you can’t configure the device with the EByte board and the relative software, I think the devices have some problems.
Try to change the software with the version I put on Git Hub here.
Probably, the FTDI does not have sufficient power to control the device on configuration storing.
Give me a feedback.
Bye Renzo
