Bluetooth (ESP32 SPP) component

Bluetooth slave component designed to run on a ESP32 providing legacy SPP functionality. BT Legacy functionality must be switched on via the sdkconfig file.

Component Pack

FREE

Detailed description

No detailed description exists yet for this component

Examples

A simple example file showing how to send and receive data using the ESP32 Bluetooth Serial Port Profile.

FC6 Icon.png ESP_BT


The SPP legacy bluetooth mode must be enabled in the ESP32 config file to allow SSP to work. For details please see this forum topic.


For problems sending strings or missing data bytes, please see this forum topic.
