emcu 14:62abee5e269d 7 Date: Mar.2016
emcu 14:62abee5e269d 8 Ver.: 1.0.0
emcu 14:62abee5e269d 9
emcu 14:62abee5e269d 10 Note:
emcu 14:62abee5e269d 11 The original project is here: https://developer.mbed.org/components/SX1272MB2xAS/
emcu 14:62abee5e269d 12 is: SX1272 Ping Pong Demo Application
emcu 14:62abee5e269d 13
emcu 14:62abee5e269d 14 How to use:
emcu 14:62abee5e269d 15 We tested this SW on NUCLEO-F401RE
emcu 14:62abee5e269d 16 Program two kits (NUCLEO-F401RE + SX1272MB2xAS) with this SW.
emcu 14:62abee5e269d 17 Connect the KITs to the PC and open a terminal emulation (for example TeraTerm).
emcu 14:62abee5e269d 18 The TeraTerm configurations are shown below.
emcu 14:62abee5e269d 19 9600 bauds, 8-bit data, no parity
emcu 14:62abee5e269d 20 On the TeraTerm you see the link informations.
emcu 14:62abee5e269d 21 On the NUCLEO-F401RE, if all is OK, you must see the GREEN led that flashing . This means that the two KITs are working properly.
emcu 14:62abee5e269d 22 If the GREEN led flash slowly means that is not present the link between the two KITs.
