Hi,
if you don’t want M0 and M1 don’t add they in the constructor.

you can find a lot of declaration examples in the examples, or the the articles.

Hi,
yes I tested the device and It’s fully supported.
I attach also the wiring diagram.

Here the configuration for the diagram:

// ---------- Raspberry PI Pico pins --------------
// LoRa_E220 e220ttl(&Serial2, 2, 10, 11); //  RX AUX M0 M1
// -------------------------------------

Hi Matejt,
I check your code, and there is an error, M0 and M1 must be HIGH, not LOW.

If you get this example from the site, please, tell me where because I must fix It.

Hi, tarpacik,
if you get “no response” you probably insert an error, power supply, or wiring problem.

You can’t use only FTDI to program an EByte module. You need to manipulate M0 and M1.

Sorry, but I don’t know that library.
But if you follow the guide you discover that it’s very simple to create test api.
That library isn’t a big help.

I think It’s very clear, and many people use It.
What problems do you have?

Hi Grzegorz,
sorry for the late response, I found the bug introduced in the latest version, for ESP32 I must force int cast of SDA SCL, but STM32 core need uint32_t so here is the mistake.
You can find the fix in version 2.2.4.
Thanks a lot for your support.

Hi Grzegorz,
you do the begin before the pinMode declaration, that’s wrong.

You must do the pinMode of all pin, then begin then start the normal use.

I recheck the code in the first topic, and I can’t understand where you initialize the pcf.
Please start from an existing example and modify It, then send me the complete code.

Hi john,
yes, the pump work in a specified time period, and It start if tank is not full and stop if it’s full.

Hi John,
you can find a version with RTC here.

You must add an i2c RTC by sharing the pin of OLED display.
But It’s all undocumented.

I Attach the preview.

Hi Musti,
I write an article on how to manage the microcontroller deep sleep with E32, and you can find It here

Ebyte LoRa E32 device for Arduino, esp32 or esp8266: WOR (wake on radio) microcontroller and new WeMos D1 mini shield – Part 7

but for the management of E22 you can get all the information here.

Ebyte LoRa E220 device for Arduino, esp32 or esp8266: manage Wake On Radio and sends structured data – 5

Practically, when your E22 is in sleep mode, you must use the AUX pin (managed bye the E22) to wake up the microcontroller also.

If you need more information write here.

Bye Renzo

PS: I also started writing the specified section for esp8266, esp32, stm32, Arduino, and Arduino SAMD about the sleep mode.

[Renzo Mischianti]

Hi,
I think the frequencies is only for the pin PWM and you can use 50K.

Hi Moonman,
I think the best solution is to use a battery like 18650 and a step up booster to get 5v.
