How many LMIC for arduino are on the net??

I have been trying to work out the TTN in my region which is 923 AS2.
spending some time to find out how to make a 1ch gateway, which take only 1ch and 1SF.

Now it comes to the node side, most of examples use IBM LMIC and it's variation.
IBM LMIC is based on ST MCU, so some porting to arduino IDE. They all have simillar name but with different modification.  and the function to call in arduino are the same, so be very careful to install.(I believe you better have only one on it.)


1. Matthijs Skooij
https://github.com/matthijskooijman/arduino-lmic
based on LMIC 1.5
providing
raw example; used to send lora mac to other, for testing purpose.
ttn-abp
ttb-otaa
No wiki page, but good explaination on readme.md

2. Thomas Telkamp
https://github.com/tftelkamp
He has 2 git on LMIC,
1. arduino-lmic-v1.5 noted deprecated, and refer reader to Matthijs one.US915/AU915 hybrid mode
2. LoRa-LMIC-1.51 folked from Forked from things4u/LoRa-LMIC-1.51 not sure what changes has been done.

3. things4u M. Westenberg
same author as 1ch gway.
https://github.com/things4u/LoRa-LMIC-1.51
have a good documentation on http://things4u.github.io/DeveloperGuide/DeveloperGuide.html
In the readme, he state this lib is a fusion of version of Thomas Telkamp and Matthijs Kooijman and Gerben den Hartog for Ideetron on tiny.
And replaced a lighter AES lib.
tested on arduino and esp8266
example consist: esp-lmic-v1.51-Fand nano-lmic-v1.51-F

 4. Doug LaRue
https://github.com/dlarue/LoRa-LMIC-1.51
Forked from things4u/LoRa-LMIC-1.51
Not much explanation but with additional example on promini
proMini-lmic-v1.51-F

 the one in the arduino library management seems to be the outdated one of matthijs, (base on the message here: https://www.arduinolibraries.info/libraries/ibm-lmic-framework)
and this arduino-lmic-v1.5 is noted outdated in github.

 very very confusing right? so which one for tonight?

    I am also trying to find out how to change the frequency of the Heltec ESP32 Lora board to AS923 and use it as an end node and connect to TTN via OTAA.
    Seems to me there’s no example available to define the frequency, SF and Channels used for this band so one may have to define it from scratch - following the suggestions by the TTN github’s global_conf.json.

Heltec ESP32+OLED+Lora, hardware testing

圖片
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-SX1276-ESP32-Oled-display-Bluetooth-WIFI

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 marked SD(esp8266), but it w

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
