Send GPS data to a Lora Local Node using the Heltec Cubecell GPS Borad

KOREK-Lora-GPS_tracker_CubeCell_GPS-6502

Description:

Send GPS data to a Lora Local Node using the Heltec Cubecell AB02S Board

Features:

Transmit data with AES with Base64 encoding

Scenario:

• 1. Receive conf from Local Server see https://github.com/MathieuB1/KOREK-WifiLora-GPS_tracker (AES key + Name + Sleep Frequency)
• 2. Get GPS and Send it to a Lora Local Node Server
• 3. Sleep each 30 seconds for waiting a "po", then send a "pi"
• 4. Trigger GPS until whistle timeout
• 5. Clear conf on EEPROM

How to install:

• 1. Install arduino https://www.arduino.cc/en/software
• 2. Install Cubecell package for Arduino https://heltec-automation-docs.readthedocs.io/en/latest/cubecell/quick_start.html
• 3. Add aes.h, aes.cpp, Base64.h, Base64.cpp to files to Arduino
• 4. Compile and Upload the code by using the Arduino GUI

Receiver

• The receiver is written in mycropython on esp32 board see https://github.com/MathieuB1/KOREK-WifiLora-GPS_tracker

GPS got stuck in data acquisition

Seems an issue when entering in lowPowerHandler mode issue

HelTecAutomation/CubeCell-Arduino#230

Seems comming from millis() after lowPowerHandler entered. In my case I fixed the gps to 9600 baud and use my own GPS_Air530Z.h where I removed everything regarding guess gps baudrate.

https://github.com/MathieuB1/KOREK-Lora-GPS_tracker_CubeCell_GPS-6502/blob/main/GPS_Air530Z1.h

After fixing the GPS I need also to send a Lora message, and I get stuck there. Will not dig into libs but seems related to Radio.send().

I've finally implemented watchdogs on both to get out of this.
