Serial Port Profile with CC2650 and CC2640R2 This test based on code from TI support under link: For CC2650: https://github.com/ti-simplelink/ble_examples/blob/ble_examples-2.2/docs/spp_ble.md For CC2640R2: https://github.com/ti-simplelink/ble_examples/blob/simplelink_cc2640r2_sdk-2.20/examples/rtos/CC2640R2_LAUNCHXL/bleapps/simple_serial_socket_client/readme.md In this experiment, I use CC2640R2 as Server (Peripheral) and CC2650 as Client (Central) as the image below: Step1: import project spp_ble_client_cc2650lp (app and stack) for CC2650 Step2: modify Code of Service in file serial_port_service: C0E0 ==> C0C0 C0E1 ==> C0C1 C0E2 ==> C0C2 If you don't change, Two Blue Tooth Board cant know to service each other. Step 3: import project simple_serial_socket_client_CC2640r2 for CC2640R2 here we using RealTerm...
