RTL_433 on beaglebone hacking for general 433Mhz device(weather station)

I have a Chinese made weather station, it comes with a station and a receiver panel


I try to get the data out, there is a way using RTL-SDR...and the lib is ready, for a lot of protocol on the market...

https://github.com/merbanan/rtl_433

building step:

fro debian:
sudo apt-get install libtool libusb-1.0-0-dev librtlsdr-dev rtl-sdr build-essential autoconf cmake pkg-config
then clone the git

 git clone https://github.com/merbanan/rtl_433.git

Installation using CMake:
cd rtl_433/
mkdir build
cd build
cmake ..
make
make install
then run
rtl_433

I got my weather station data, and some one else...

I live in a 11 flowers building, I setup the weather station on the roof, my room is in 7th floor, I got nothing from the receiver.
So the first thing comes to my mind is to upgrade the antenna inside the weather station.

it took me a while to  open up the station, since it's all siliconned.

you also need to release the wire of temp and humidity sensor from the button side, otherwise you will have difficulty to get the PCB up.
the antenna seems not so promising, as usual...















I replaced it with an antenna I made long time ago...https://ldsrc.blogspot.com/2014/08/12-wave-dipole-antenna-testing.html


Then put the weather station back to the roof, and my SDR near the windows.I start to get some info from SDR, but not at 1data/minute, seems there are some data mission.

a better antenna seems good solution to my situation. I did the same for the receiver.
Then I got clear data even I put the receiver "indoor"



some one decoded the same weather station

There are few ways you can decode OOK without RTL-SDR, using a 433Mhz rf

There is also a lib for RFM69W

Heltec ESP32+OLED+Lora, hardware testing

you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-S...

micro SD card for ESP32, on lolin32 with OLED and heltec 32 lora oled

圖片
I have purchased 2 micro SD card holder for my esp project. First I would like to test with heltec esp32 lora oled module. this module uses: sck=05 MISO=19 MOSI=27 SS(lora)=18, then I assigned 21 for sd SS and there is a lib in esp32-arduino, which use SS default at 5 I took the example and use SD.begin(21), but I alway get the error: entry 0x40078a9c Card Mount Failed But I do saw once that it read out the sd card type and volume. Not sure it's the issue of lora sd card swithing, or it just can't work. The other esp32 card I have is an wemos esp32 oled, it did not leave me too much pins, I need to find out how to connect sd to it. But I have wemos D1 mini esp8266 on hand, and connect it as:  * The WeMos Micro SD Shield uses:  * D5, D6, D7, D8, 3V3 and G  *  * The shield uses SPI bus pins:  * D5 = CLK  * D6 = MISO  * D7 = MOSI  * D8 = CS It's not working with the example in the arduino IDE 1.8.5, which m...

AIS0. understanding AIS NMEA 0183: How it's coded

For my boat tracking system, I found out that using AIS format seems to be a good idea, at least I don't have to worry about how to present boat data, since there are already plenty things for do this on mobile phone or PC. Here is what I read: http://catb.org/gpsd/AIVDM.html Looking into AIS NMEA0183, it has much more application then I think. Such as MOB device, epir, aid to navigation device...etc, all are included. it use the first few char to indicate the function: Table 1. AIS talker IDs !AB NMEA 4.0 Base AIS station !AD MMEA 4.0 Dependent AIS Base Station !AI Mobile AIS station !AN NMEA 4.0 Aid to Navigation AIS station !AR NMEA 4.0 AIS Receiving Station !AS NMEA 4.0 Limited Base Station !AT NMEA 4.0 AIS Transmitting Station !AX NMEA 4.0 Repeater AIS station !BS Base AIS station (deprecated in NMEA 4.0) !SA NMEA 4.0 Physical Shore AIS Station It can also be used between device on boat for message communication, AIVDO The...
