Constructor difference and HardwareSerial and SoftwareSerial difference

[ludophot]

Hi, I have a few questions for my understanding

• what is the difference between : LoRa_E32 e32ttl100(2, 3,5,6,7); and LoRa_E32 e32ttl(2, 3,5,6,7); ?
• what is the difference between serial and hardware the interest of everyone?the most efficient method?

thank you 🙂

Hi Ludophot,

for

LoRa_E32 e32ttl100(2, 3,5,6,7); and LoRa_E32 e32ttl(2, 3,5,6,7)

change only the variable name e32ttl100 in e32ttl.

 

I think you mean difference from

LoRa_E32 e32ttl100(2, 3,5,6,7); // Arduino RX <-- e22 TX, Arduino TX --> e22 RX AUX M0 M1


and

#include <SoftwareSerial.h>
SoftwareSerial mySerial(2, 3); // Arduino RX <-- e22 TX, Arduino TX --> e22 RX
LoRa_E22 e22ttl(&mySerial, 5, 6, 7); // AUX M0 M1


and

LoRa_E22 e22ttl(&Serial1, 5, 6, 7); // AUX M0 M1


the first and the second is the samething the difference is that in the first case I instantiate SoftwareSerial internally.

The last one you pass a reference of the HardwareSerial.

 

The better solution is to use HardwareSerial, because SoftwareSerial is an emulation of Hardware one, so to do the emulation need more processors time respect an hardware implementation of the Serial, and can be more fast.

But not all Arduino like have multiple Serial, so for Arduino UNO, if you want use debug and other you need to do Software one.

 Arduino RX <– e22 TX 
we see that you work on the E22

Hehehehhe… you discover me…

yes the library is ready and tested,

the base commands is the same of library for E32 but there are addictions of the new features like RSSI, configuration for repeater mode packet size increased etc. etc.

I start writing documentation, a library without documentation is half work..

But probably first I release the “EByte E32 Web Manager“,  a web manager to configure and test E32..

I ordered 2 E22 in anticipation of the release of your library.

Repeater mode interests me a lot because I used it on NRF24 modules. do the E32s lack it? the rssi? measurement of the power level when receiving a signal

[Renzo Mischianti]

No E32 doesn’t have RSSI and repeater function.

E22 can reach a greater distance with less power:
from 3Km of E32 to 4/5Km of E22
from 8Km of E32 1W to 10/12Km of E22

The packet size of E22 is configurable from 32Kb to 240Kb.

It’s also more difficult to find module versione, so for the first test I use a PCB as adapter

Ebyte LoRa E22 device for Arduino, esp32 or esp8266 3 devices module SMD

Hello, about EByte E32 Web Manager, do you already have the configuration software available for download?

[Renzo Mischianti]

Hi Thayro,
you are right, has been ready for months, i try to publish as soon as possible.
Bye Renzo

[Renzo Mischianti]

Hi Thayro,
I release It, you can find the program in the example list of Library.
Bye Renzo
