This video will describe how to configure the Ebyte E32 series LoRa radio module using the UART on a microcontroller. On power up the microcontroller can configure an off the shelf LoRa module wih a configuration profile compatible with the project.

My brain always feels better after watching one of your videos because you communicate so well and evey thing makes sense, unlike lots of things happening in the world that don't compute. Thankyou 0033mer.

This seems like a great idea. The only concern I would have is if the persistent memory on the ES32 LoRa module could have a write cycle limit challenged if the settings are resaved too often. I don’t know enough to know if this is a realistic problem, but it did occur to me. I don’t think I’ll ever work in FlashForth, but I always enjoy your projects. I understand enough that the techniques can be applied to other systems. Thanks for sharing with us.

Yes, that is a valid concern if the LoRa module is going to be power cycled many times. There are a couple of ways around this problem. If you send the control byte $C2 instead of $C0 before sending the 5 config bytes they will be written into RAM, so you would have to do this on every power cycle. You can also apply a jumper that shorts one of the GPIO inputs to ground before power up and the code will see this and send the config packet. I use this method on my solar powered nodes. Thanks for sharing.

Could the MCU ask the LoRa module what its config is and change it only if necessary or if it doesn't get an answer?

Yes, the MCU can read the current configuration values and change them as necessary.

I dont know what is wrong, w/ lora on default setup ( that it was when i bought ), they communicate, after setup to use fix mode, changing the addH chan, they stop communicate.

@0033mer Жыл бұрын

In fixed mode you have to send a three byte header containing the address and channel before you send the data packet. Check out this video: kzfaq.info/get/bejne/gNxydpqUqs2tYHk.html

If you use the E220-900T30D module (LLCC68) it has the standard UART interface which is code compatible to the E32 series.

To get started you do not need any code. An FTDI connected to the LoRa module connected to a computer (USB) running TeraTerm will allow you to send data.

@@0033mer i have a e220 900m22s. Is that compatible to your methods with your e32 series? Mine has miso mosi sck. I can send cmds via miso mosi and program the chip's registers (verified by reading them back out). But i can't get it broadcast anything (i listen with sdr radio).

@0033mer Жыл бұрын

Your module is not compatible with E32 code. E220-900T22D would be compatible. Check out the LLCC68 protocol documentation from Semtech. It looks like you need to enable and ramp up the Power Amp (PA) to send out data in the data buffer. Since you can communicate with the module, you are missing the simple command to enable transmission. Check out the SetTx commands.

What is airrate vs uartrate ?

@0033mer Жыл бұрын

The data speed over the wireless radio link is the air rate. The speed of the microcontroller UART feeding the RX pin on the LoRa module is the UART rate.

@0033mer Жыл бұрын

The serial Tx/Rx pins on the Arduino UNO/Nano are used by the USB to serial (FTDI) circuit so there will be a conflict when you send hex code using these pins. If you are serious about building projects with Arduino and LoRa use a software serial port which use different pins or goto a Pro-micro board which has a free UART serial port.
