I agree with you. I bought a Fire and a Core2 with two Lora modules, in the Fire it fits perfectly and in the Core2 it does not. Now it will force me to buy another Fire if I want to use another type of module. I have not been able to use them.

I don't think it's a good policy, in the same brand, not to make everything compatible. This is my personal opinion

Thank you for your response. You are absolutely right it doesn't look very good. It looks like all text is in bold 12 and accented characters in plain text 10. Not a very elegant solution.

I don't know, I am not an expert in Lora. But you talk about a distance of (300m - 2km max) and the article, without external modification, is 20m if I remember correctly.

How can I tell IUFlow that the document is in Unicode? This is the original:

Doncs no...però jo l'aniria a buscar!
Barça - compañía aáàâä

and this is what appears on the screen, read from the SD card,

Doncs no...per jo l'aniria a buscar!
Bara - compaa a

Thanks in advance

Take a look at this lesson to see if this Lora module is right for you.

Hola @sinzapatillas

COM.LoRaWAN is a LoRaWAN communication module in the M5Stack stackable module series, supporting node-to-node or LoRaWAN communication. The first is only point-to-point and LoraWan allows you to connect to the network.

Here is a link to an article by Philip Stewart to make it clearer to you.

Hola @felmue

I just saw your photos on the Core2, but I don't think it all fits together. For the moment I leave it on hold, I just installed IUFlow on the Fire and I'm going to practice a bit with it.

Hello @felmue

If you remove the white board from the Core2 and want to insert the Lora module, the slot is too small and does not fit. You will have to have some modules for the M5Stack, I hope all models are compatible, and other modules for the Core2.

In short if I want to use Lora I have to buy another Fire or similar.

Thanks for your information and link @felmue

My initial idea was to buy two TTGO LoRa32 but I preferred these two cores because I saw that they had Lora modules. For the moment I'm going back to the NodeMCU that I find much more comfortable and in a few months I will look at the M5Stack again.

Thank you for your time

I have an M5Stack Fire and a Core2 and two Lora modules. The idea is to use one to send and the other to receive. The examples LoraSender and LoraReciber are only for M5Stack,
is it possible to use the Lora module between a Fire and a Core2, or can they only be used with the M5Stack?

Thanks in advance
Carles

Thanks for the reply @wa-berlin. I see that each core is different and the way to calculate the battery level are completely different between Fire and Core2. Particularly I think that being from the same company should be similar programming with the prefix difference of the core, ie: M5.Power.xxxxxxxx = M5.Axp.xxxxxxxx

Thanks again @world101

I have seen it. But I think it would have to be in the model documentation, if it is I missed it.

Have a nice day

Hello @felmue
I would just like to know if the values were correct. Thank you for your explanation.

If I am not confused, my English is not good, there is no function like in Fire M5.Power.getBatteryLevel(), to know the percentage or actal battery level.

Thanks for your time
Carles

I have to pry it out of the two slots it has? Remove the screws with a screwdriver?, the one with Fire does not work. Another way?

Thanks in advance,
Carles

With the Fire using the function M5.Power.getBatteryLevel(); gives you the battery level. With Core2 it is not clear to me. I have used a number of functions connected and not connected to the USB. I detail them below:

USB:
float batVol = M5.Axp.GetBatVoltage(); // 4.21
float batCur = M5.Axp.GetBatCurrent(); // 14.00
float batPow = M5.Axp.GetBatPower(); // 0.00
float batCha = M5.Axp.GetBatChargeCurrent(); // 14.00
bool charging = M5.Axp.isCharging(); // 1

Without USB:
float batVol = M5.Axp.GetBatVoltage(); // 4.16
float batCur = M5.Axp.GetBatCurrent(); // -88.5
float batPow = M5.Axp.GetBatPower(); // 462.39
float batCha = M5.Axp.GetBatChargeCurrent(); // 0.00
bool charging = M5.Axp.isCharging(); // 0

I see very different values depending on whether it is connected or not. Can someone explain to me if this is correct or if there is a problem with the unit?

Thanks in advance

Thanks again @world101 , solved. Ho I'm really bad looking for M5Stack documentation, or documentation is missing.

I understand that the contacts have to go on the bottom front, or am I wrong. As the front, where it carries the pins, is narrower, than the back goes in crooked (twisted) and I don't want to force it.

I hope you understand my English is not very good.
