PlatformIO

WIP: TTGO T-Wristband Example

First steps with TTGO T-Wristband. Product page.

Developed with PlatformIO

Includes a paged interface framework.

Disclaimer: Still work in progress. Currently I'm facing issues regarding battery duration (You can follow the issue in the manufacturer's repo). PRs are welcome.

User interface

Currently available pages

Build and Flashing

First of all, install PlatformIO with your favourite IDE (i.e. VSCode). Follow this instructions.

Clone the repo

git clone https://github.com/TioRuben/TTGO-T-Wristband.git

Open cloned folder with your PlatformIO IDE (in the example, with VSCode)

cd TTGO-T-Wristband
code .

In the first flash, edit platformio.ini and comment all upload config (upload_protocol, upload_port, upload_flags):

Connect wristband via USB with the supplied daughter board. In Windows 10, drivers are installed automatically. I guess with other OS will be automatically installed too.

After plugging wristband, please select env variant esp32dev on VisualCode and build it, PlatformIO icon->env:esp32dev->Build:

Upload Button

then, in the same menu, plase select upload.

or build and upload it with the pio command line:

pio run -e esp32dev --target upload

PlatformIO will build and upload the binaries to the TTGO T-Wristband via USB.

OTA Upload

After first flashing, you can use OTA upload. First of all, go to battery or OTA page in the wristband. Then maintain the wristband button pressed. If your Wifi is still not configured, you will see an screen asking you to connect to the wristband AP. Connect to It and follow the instructions in the captive portal to configure wifi (more info: WifiManager).

Once configured, you will see the "waiting for ota" message in the screen. Find your wristband IP Address, in your platformio.ini please enter the IP address in the upload_port config:

[...]
[env:esp32devOTA]
platform = espressif32
board = esp32dev
framework = ${common_env_data.framework}
monitor_speed = ${common_env_data.monitor_speed}
upload_protocol = espota
upload_port = [YOUR_IP_ADDRESS]
[...]

It's supposed to work with hostnames, but sometimes fails.

Press the upload button in PlatformIO

Upload Button

or build and upload it with the pio command line:

pio run --target upload

The project will compile and upload to the wristband via WiFi (OTA).
