“In Bluetooth Classic (BR/EDR) systems, a Serial Port Profile (SPP) is an adopted profile defined by Bluetooth SIG, to emulate a serial port connection over a Bluetooth wireless connection. For Bluetooth LE, an adopted profile for implementing SPP over BLE is undefined, thus emulation of a serial port must be implemented as a vendor-specific custom profile”
Has anyone on this forum been successful in implementing a BLE to UART bridge (ie. something similar to Bluetooth SPP / serial port profile) for BLE?
Thanks, - Peter
In BLE, you may use a Custom profile with a custom service ( with UART Rx characteristic and UART Tx Characteristic with Notify property) to implement a BLE to UART bridge similar to SPP in BT.
