GPS module used by 3DR

It comes an idea of using 3DR gps module for other applicaiton, but few things need to knowL:
1. it's not a NEMA one, the one I have iswith ublox chip, 6 or 7, by default,it communicates through uart at 38400bps, and it use an other portocol UBX, which is an binary one.
different chip has different config file:
https://github.com/ArduPilot/ardupilot/tree/master/libraries/AP_GPS/config
it can be loaded to gps by uusing u-center from ublox
https://www.u-blox.com/en/product/u-center-windows

the config used by 3DR has majorly following out put in UBX

00:08:24  R -> UBX NAV-SOL,  Size  60,  'Navigation Solution'
00:08:24  R -> UBX NAV-SVINFO,  Size 208,  'Satellite Status and Information'
00:08:24  R -> UBX NAV-STATUS,  Size  24,  'Navigation Status'
00:08:24  R -> UBX NAV-POSLLH,  Size  36,  'Geodetic Position'
00:08:24  R -> UBX NAV-VELNED,  Size  44,  'Velocity in WGS 84'
00:08:24  R -> UBX NAV-CLOCK,  Size  28,  'Clock Status'

 But there are some out put not clear.

Idea is to see how to config ublox with only few info at desired rate.

I can chage the out put of serial1 form cfg-prt :
change the out put to ubx only, but not able to change it to NEMA:
in fact it dose change to NEMA, but in CFG-MSG, NEMA did not config to out put on serial1
I can also change baud rate,.

as well as frequency in CFG-RATE, by changing measurement period to 1000ms as 1HZ

it changes to:
00:20:10  R -> UBX NAV-SOL,  Size  60,  'Navigation Solution'
00:20:10  R -> UBX NAV-STATUS,  Size  24,  'Navigation Status'
00:20:10  R -> UBX NAV-POSLLH,  Size  36,  'Geodetic Position'
00:20:10  R -> UBX NAV-VELNED,  Size  44,  'Velocity in WGS 84'

 I wish to take out navigation solution and velocity.
To do so , go thUBX_CFG_MSG,
and select the message in the drop box,
like 01-060NAV_SOL
 and then do the check on uart1, unckeck




So, I leave only 01-12 NAV-VELNED and NAV-POSLLH
and go to
CFG-CFG and "save current configuration"

unplug and re-start, it comes at 38400 and only 2 ubx out put, remember to select EEPROM as well.

So I have config a gps send out only GPGGA at 5Hz.
Which I plan to connect to a wireless serial stuff, to send to mission planner

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-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...
