Server Configuration¶

Telemetrix4RpiPico2w-BLE¶

BLE Default Advertising String¶

The BLE server uses the default advertising string of "Tmx4Pico2W". It is defined near the top of the BLE server sketch.

To modify the advertising string, search the server sketch for:

#define PICO2W_ID "TmxPico2W"

Place the new string between the quotation marks.

Setting The Advertising String In The Telemetrix4RpiPico2w-BLE Python Class¶

Set the ble_device_name parameter to match the value set in the BLE server sketch.

TelemetrixRpiPico2Ble

class TelemetrixRpiPico2Ble (ble_device_name='Tmx4Pico2W',
                             sleep_tune=1e-06,
                             autostart=True,
                             shutdown_on_exception=True,
                             reset_on_shutdown=True) 

Setting The Advertising String In The TelemetrixRpiPico2wBleAio Python Class¶

Set the ble_device_name parameter to match the value set in the BLE server sketch.

class TelemetrixRpiPico2wBleAio (ble_device_name='Tmx4Pico2W',
                                 sleep_tune=1e-06,
                                 autostart=True,
                                 loop=None,
                                 shutdown_on_exception=True,
                                 reset_on_shutdown=True,
                                 close_loop_on_shutdown=True) 

Enable The Bluetooth Stack Before Compiling The BLE Server¶

Before compiling a BLE server, you must configure the Arduino IDE to include the BLE stack. To do so, in the Arduino IDE, select Tools > IP > Bluetooth Stack, then IPV4 + Bluetooth.

Telemetrix4RpiPico2w-Serial¶

The serial server requires no configuration.

Telemetrix4RpiPico2w-WiFi¶

Required Configuration¶

SSID¶

Edit the sketch and place your router's SSID between the quotes.

PASSWORD¶

Edit the sketch and place your router's PASSWORD between the quotes.

Save your changes.

Upload The Server To The Pico¶

Select the board and port on the Arduino IDE.

Next, plug your Pico into a USB port and upload the server by pressing the upload button on the Arduino IDE.

Startup Information Sent To The Arduino IDE Serial Monitor At Server Power Up¶

If you enable the Arduino IDE's serial monitor, when you first power the Pico2w, you will see information strings appear for each server type.

Allow 15 seconds for connection to complete................
Connected to WiFi. IP Address: 192.168.2.212  IP Port: 31335

It may take several seconds for the Pico2w to connect to your router. A connection progress string is displayed. When you first power the Pico2w, the board LED lights and stays on until a successful connection to your router is established. The IP address assigned to the Pico2w by the router is displayed, along with the IP port number.
