Bluetooth
Posted: Sun Jan 31, 2021 8:56 pm
I have a serial data communication between two ESP32 in SPP bluetooth mode. The master must transmit a sequence of 32 bytes to the slave which, after receiving the data, waits about 1mS and sends the response to the master with a sequence of 32 bytes. This cycle must be repeated over and over. From tests carried out, however, I notice that the minimum interval time between transmission and reception is 15mS in SPP mode so I can't reach my goal.
