Smart watch band for Heart Rate and GPS via Lora sending #2274

Closed rayhong77 closed 4 years ago

rayhong77 commented 5 years ago

Hardware:

Board: ESP LoRa32 TTGO 3pcs Core Installation/update date: 2/JAN/2019 IDE name: Arduino IDE with espressif Flash Frequency: ?40Mhz? PSRAM enabled: YES Upload Speed: 115200 Computer OS: Windows 10

Description:

Hello, I am such a newbie of these arduino things.

It's TTGO ESP32 LoRa Board, I connected Max30010 to 21,22 PINs and will connect Neo-6m GPS to 16,17 PINs.

Before GPS connection, I tried Heart Rate sensor works first and it works standalone with max30100 library. However, as my code as below, i mixed serveral codes for working together. They would conflict each pox.begin(HR sensor) with others. Maybe SPI and U8g2 When screen and LoRa work well, the heart rate sensor can't read the value(IR LED is okay). I used libarary includes file without modifying.

I am stuck for this problem. please advice me. This is so important project for me. i worry about GPS connection too.
