LoraGateway with RAK2245 and Pi zero W

 

I　have a rak2245 pi hat, 


it's designed for pi3, but I wish to use on pizero W, since a simple forwarder won't use too much power.



After the assembly, the search start!


Documentation from RAKwireless: https://downloads.rakwireless.com/LoRa/RAK2245-Pi-HAT/

page of start guide: 

https://docs.rakwireless.com/Product-Categories/WisLink/RAK2245-Pi-HAT/Quickstart/

the firmware is made for pi3+ or Pi4. to apply to pi zero W, you have to be careful with gateway EUI, since the TTN gateway EUI is a manipulation of Mac(add FF FE in middle), the firmware use ether mac, you have to choose wireless wlan0 on zero W.


RAKwireless also make a pi zero w gateway as wise Gate Developer D0+

WisGate Developer D0+ is a LoRaWAN® developer gateway with GPS function. It is a device composed of a the RAK2246 Pi HAT LPWAN Concentrator module and Raspberry Pi Zero W.

Class A and C compliant based on Semtech® SX1308 chip

while looking for firemware there is a rak doc center state all the firmware:

using the firmware provided by rakwireless, I tried the one for RAK2245 and for wise Gate D0(rak7246), 

Both started as AP. but you have to wait, the AP first shown as Rakwireless_xxxx, few minutes later it will reboot and come up with a SSID where xxxx are replaced by last 2 bytes of  mac of wlan0.

I was able to config the wlan, and using the gateway-config tool to select TTN frequency plan. it does not make correct gateway ID nor the server address. 

check the global_conf there are several ones now:


I used nano to edit the 923_925 one, in the file, the gateway ID is all "0", you need to the one pop in the start of gateway config, which is the mac address with FF FE added at midle.

Then change the servoer_address to your selection in TTS V3.

After reboot, I got my 2nd gateway shown on TTs V

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

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

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

Install Network Time Protocol(NTP) on BeagleBone with Angstrom linux and set local time zone

Referenced from : http://cwraig.id.au/?p=513 1. Update your Package List opkg update 2. Get the ntp Package opkg install ntp ntpdate Update 2014/07/03 for the latest beaglebone image(2013-06-20) with kernel 3.8.12, after this installation,  system will add to service list, so only need to change time zone 3. Now we need to stop the ntpd service so we can request a manual update /etc/init.d/ntpd stop manual update ntpdate pool.ntp.org type in date, you should see the date is changing to current date and time, but the time zone is not corrected. The time zone info is contained in /etc/localtime , use this to remove it: rm /etc/localtime before link up our time zone, look into /usr/share/zoneinfo folder for your timezone. I did not find taiwan in asia, not plan to use hong_kong, but there is still: /usr/share/zoneinfo/Etc/GMT-8 now we make the link with ln command ln -s /usr/share/zoneinfo/Etc/GMT-8 /etc/localtime now type date again to check, should ha
