Meshtastic 03 adding GPS on TTGO lora32 V2

圖片
 I wish to add GPS on my running meshtastic client on TTGO lora32. I have a GPS module outputs with nema at 9600bps. In the config app, in the position sector, you  can find the redefine of PGS pins. I firstly use IO00 as GPS_RX_pin. But it does not work. I guess the web config use 0 as none-config default. Then I want to know what is the default pin for GPS in meshtastic for TTGO Lora 32, I use the 2.4.x firmware for V2.1-1.6. Checked the git, there is no default gps pin for this hardware, so I changed the gps to mcu pin to 34, leave other pins stuff as 0 and do the config .  And it works. there is a new flasher, which still has LILYGO T-Lora V2.1-1.6 as board selection, with latest 2.5.xx firmware maintain 34,0,0 setting is no longer working. after few try, I decided to set to 34/32/25, where 32/25 are free pin on my board. I also reference to  LILYGO Meshtastic T-Beam V1.2 ESP32 LoRaGPS WiFi , it has a gps on 34/12 with 34/12/0 the setting is still working

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...

ELRS on Pixhawk 2.4 with ardupilot

I still have few old FC:3DR pixhawk   I have try to connect my ELRS 2.4G rx to it. since you got RC control and telemetry on one little receiver. But ELRS is relatively recent, not much resource on it. There are also different version of clone. but when flashing with mission planner, it says this is FMUv2 I have set up and bind tested my ELRS  https://ldsrc.blogspot.com/2023/05/crsf-lers-decode-with-arduino-leonardo.html I know it works on RC channel output. First thing is to know the Serial port Nr in mission planner mapping to the labels on my pixhawk. Lucky the mapping is quite straight forward. Pixhawk FMUv2 / Cube FMU v3 Serial Mapping The I follow this instruction: to set serial protocol at 23, and othe https://www.expresslrs.org/quick-start/ardupilot-setup/ My ELRS is at V.3.2.1, we can set the baudrate, since we set 115 in pixhawk, I also set the same in ELRS RX. then it's the chaos...I tried different ports, different baudrate, invert TX/RX(which is not necessary on b...
