Yyoucef_ali What is the max date bit rate transmission using Lora Wan ?

jjbitnic👀•5/20/24, 11:52 AM

The LoRaWAN data rate ranges from 0.3 kbit/s to 50 kbit/s per channel.

So guys just wondering though. If you could embed a tiny computer system anywhere, let's put power considerations aside, where would you put it and what would it do?

jjbitnic👀•5/20/24, 5:04 PM

Lora and in particular lorawan is meant for small data packets every few minutes or so. But you can have thousands of them on a wide range. Anything with needing wide band or critical response time is probably better using other means of communication.

I would embed a tiny computer system in a pair of sneakers that analyzes your running form, tracks distance and pace, and even coaches you in real-time to improve your stride efficiency and prevent injuries! It could connect to a smartphone app for detailed data analysis and personalized training plans.

Hey @Daradrio Great! if you're looking to get your hands dirty with embedded protocols like Serial UART, I2C, and SPI with 32-bit MCU like STM32 Cortex-M4 (backed by live project and use cases). I invite you to join this Sunday's Engineering Hour. I'm sure you'll find these upcoming events helpful. Have a good day!

Does anyone worked on SIM800L module with ESP32 using ESP-IDF framework?

I tried the basic pppos_client esp-idf example, but it's not working for me

I'm getting tthe following errors
E (10484) esp-modem: esp_modem_dte_send_cmd(256): process command timeout
E (10484) dce_service: esp_modem_dce_sync(225): send command failed
E (10484) sim800: sim800_init(159): sync failed

Yyoucef_ali hmm modeste data

InsightMike•5/22/24, 11:59 AM

Yes, the low data rates enable the very long range. It's also important to note that, if you follow the specification, that the data rate isn't under your control, it adapts to the RF conditions. You can force certain data rates to fit your application, but then you will have range trade-offs and may give up full interoperability with other LoRaWAN devices (which may or may not be important to you).

wafa_ath•5/22/24, 7:06 PM

hello @iamnarendrans Have you tried using a serial terminal program to communicate directly with the SIM800L using AT commands? just to know whether the problem lies with the communication between the ESP32 and SIM800L (hardware or software configuration)

wafa_ath•5/22/24, 7:08 PM

also A voltage regulator might be necessary if your power supply isn't stable. What is the voltage level you're providing to the SIM800L?
