STM32 E22900T22D LoRa Transceiver Module and Range Test

[@Jose-tw9bl]

Thanks for showing and explaininh your code! I've had a hard time with understanding how to organize libraries and import them

[@johneagle4384]

Thank you. Very interesting code and experiment. This a very useful video.

[@usefulelectronics]

Thank you for the awesome feedback!!

[@mast3rbug]

For line of sight communication, you can do the same distance with 2.4 ghz

[@usefulelectronics]

Yes but you will need a very big antenna for that

[@mast3rbug]

@usefulelectronics Normal whip antenna works fine for this distance

2.4Ghz is overly congested, low powered, and terrible outside. Lora typically uses 900~Mhz range, and will penetrate walls and foliage easily. LoRaWAN vs. Wi-Fi wireless technologies The best way to describe the LoRa vs. Wi-Fi discrepancies is to go back to the basics. Any network type can only have two of three characteristics; long-range, low power consumption, and high bandwidth. While Wi-Fi is superior when it comes to bandwidth, it suffers when it comes to battery life and range. Most networks might struggle to work past 15 meters, which makes them unsuitable for scattered IoT devices. In comparison, the low power and long-range nature of LoRa make it ideal for these devices. However, LoRa will struggle to send a single image, let alone large files. It thrives at sending small packets of data, such as temperature and humidity. Lora can work from 1 ~ 10km

Hi sir. I have a question. The library or driver files that you use (e22900t22d.h and e22900t22d.c). We can use the LoRa modules without these files right? Since the stm32 board run with LoRa as default, as you said before.

Hi, i´m using the E32-433T30D model, maybe u know whtar LoRa gateway can i use for this E32? I know that i can build a gateway with one raspberry + LoRa Hat, but there is no that HAT in my country :/

[@KhiemNguyen-oo9yp]

Hi i want to know how you can send and receive the packet between 2 lora simultaneously because i have already chosen the transparent mode for the 2 lora in the configuration app but when my lora is receiving a message it cannot transmit my instruct to request another different packets from the other lora.

[@usefulelectronics]

You can’t do that You can design your system to operate as slave master so you can expect when to receive data

Kablosuz bir transistörü tetiklemek istiyorum kod yazmayı bilmiyorum ayrıca arduno benzeri hazır modüller kullanmak istemiyorum bunu nasıl yapabilirim?

[@mirovskii]

Hi sir, thank you for the video and explanations. I want to ask that, can't we use the LoRa modules without using FreeRTOS? Do stm32 boards not include the needed softwares for that?

[@usefulelectronics]

Adding FreeRTOS is an optional feature. STM32 runs without RTOS by default. So yea you can use LoRa module without using RTOS

[@mirovskii]

@@usefulelectronics Thank you for your response. I made the project to communicate 2 stm32 blue pill boards. When I arrange the wiring just for the UART communication between boards, it works. But after I change the wiring according to the LoRa e22-900t22s modules, it does not work. I am sure about the wiring, parameters like baud rate, channel etc. What could be the issue?

[@yabruhpraneeth]

can u tell me how to connect power and what have u used for providing power ?

[@usefulelectronics]

@@yabruhpraneeth I have used power bank that supplies 5V to my system

[@dheerajreddy1275]

Can we use NODE MCU ESP-32S instead of STM32 MCU?...If yes can you please explain me about that sir.

[@usefulelectronics]

@@dheerajreddy1275 yes sure you can You can use the same module driver but the UART layer will change to suit ESP-IDF

[@Zurenio]

Can you give me a purchase link to buy the antenna...?

[@serhatturk4415]

"I am getting 'Module no response' error every time I try to configure the RF settings. How can I fix this?"

[@usefulelectronics]

You need to change M0 and M1 voltage level for configuring the module check out the data sheet

Great video!

[@hatemzaatra211]

Great video

[@Dark_Phoinix]

Hi , communication is bidirectional ? or one way only? E22900T22D ---> E22900T22D or E22900T22D E22900T22D ?

[@usefulelectronics]

Bidirectional

[@Dark_Phoinix]
