Ebyte LoRa E220 LLCC68 device for Arduino, esp32 or esp8266: configuration – 3

Spread the love

LoRa or Long Range wireless data telemetry is a technology pioneered by Semtech that operates at a lower frequency than NRF24L01 (433 MHz, 868 MHz, or 916 MHz against 2.4 GHz for the NRF24L01) but at thrice the distance (from 5000m to 11000m).

Now we try to examine better how to configure the Ebyte E220 UART LoRa device based on LLCC68 Wireless Modules.

Ebyte LoRa E220 LLCC68 device for Arduino, esp32 or esp8266 Configuration

Here some devices: E220-400T22D 433MHz 5Km - E220-400T30D 433MHz 10Km - E220-900T22D 868MHz 915MHz 5Km - E220-900T30D 868MHz 915MHz 10Km

I created this library to manage EBYTE E220 especially to simplify the configuration process because can be very tedious.

If you have device freezing problems, you must put a pull-up 4.7k resistor or better connect to the device AUX pin.

Library

You can find my library here, and It’s available on the Arduino IDE library manager.

To download.

Click the DOWNLOADS button in the top right corner, and rename the uncompressed folder LoRa_E220.

Check that the LoRa_E220 folder contains LoRa_E220.cpp and LoRa_E220.h.

Place the LoRa_E220 library folder in your /libraries/ folder.

You may need to create the libraries subfolder if it’s your first library.

Restart the IDE.

Connection schemas for programming

For the primary usage, we had used a specified configuration for Arduino. Still, you are working only in “Normal mode” in that configuration. Now we will manage only the needed pins dynamic (RX, TX) to simplify the programming process and the others statically.

Pin No.	Pin item	Pin direction	Pin application
1	M0	Input（weak pull-up）	Work with M1 & decide on the four operating modes. Floating is not allowed; it can be ground.
2	M1	Input（weak pull-up）	Work with M0 & decide on the four operating modes. Floating is not allowed; it can be ground.
3	RXD	Input	TTL UART inputs connect to external (MCU, PC) TXD output pin. It can be configured as open-drain or pull-up input.
4	TXD	Output	TTL UART outputs connect to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output
5	AUX	Output	To indicate the module’s working status & wake up the external MCU. During the procedure of self-check initialization, the pin outputs a low level. It can be configured as open-drain or push-pull output (floating is allowed).
6	VCC		Power supply 3V~5.5V DC
7	GND		Ground

As you can see, you can set various modes via M0 and M1 pins.

Mode	M1	M0	Explanation
Normal	0	0	UART and wireless channels are open, and transparent transmission is on
WOR Transmitter	0	1	WOR Transmitter
WOR Receiver	1	0	WOR Receiver (Supports wake up over air)
Deep sleep mode	1	1	The module goes to sleep (automatically wake up when configuring parameters)

Wiring for programming/sleep mode

To configure It, you must set M0 and M1 to high (remember to use 3.3v).

But If you connect all pins, the library sets HIGH or LOW the pins as needed without a problem.

As you can see, I add a lot of constructors for every device, and if you change the first configuration, you can switch the device with the same code.

LoRa E32 request configuration logic analyzer Arduino — LoRa E220 request configuration logic analyzer Arduino

To get the correct information, I add some #define to change the device type (same #define manage more other devices, I create only one for type for simplicity).

#define E220_22
#define E220_30

You can select only one of them. The parameter changes the Transmission power constant as described in the configuration schema.

In the same manner, you can select one on reference frequences

#define FREQUENCY_433
#define FREQUENCY_170
#define FREQUENCY_470
#define FREQUENCY_868
#define FREQUENCY_915

You can choose only one of them. The parameter changes the reference frequencies only for display purposes,

Set configuration

Naturally, when you have a configuration you want to change for your purpose, I think you can get the configuration from a device, modify what you want and set It.

But in the example sketch, I add a set of configuration comments. You can uncomment the config you want. In the other examples in the library, there is a reference to the relative configuration to apply.

Ricorda che il parametro saveType è fondamentale per mantenere le opzioni al riavvio del dispositivo, WRITE_CFG_PWR_DWN_LOSE naturalmente perderai le impostazioni con WRITE_CFG_PWR_DWN_SAVE non perderai le impostazioni.

I’m using the define statements:
#define E220_22
#define FREQUENCY_915
for my E220-900T22D modules, but when I use the getConfiguration sketch it still see:
Chan : 23 -> 433MHz

  Hi Justin,
  try to put it inside LoRa_E220.h or parameters.h.

    Hi Renzo.
    
    Where to put it? I did it after #define LoRa_E220_h but still
    Chan : 23 -> 433MHz
    
    Thank you!

      Hi JaTo,
      Do you intend the frequencies define?
      That before the include of the library, or inside stateNaming.h file.

‘ResponseStatus rs = e220ttl.sendMessage(a)’
How can I speed up the repetition while using it in loop?

  Hi Kim,
  I think you must give us some information if you need help.
  
  But first of all, I must remember that if you don’t connect AUX, I use the minimum delay needed to complete every LoRa operation, and It’s very long.
  Bye Renzo

Hello Renzo,
I am trying to use a Nano 33 Iot, but I don’t seem to be able to make it go.
Any suggestion of that configuration I can use ?

can you please tell me how to fix this? –> e220ttl’ was not declared in this scope e220ttl.begin();

  Hi Meidy,
  It means that the variable e220ttl doesn’t exist. Probably you initialize It with another name.
  Bye Renzo
