Program two kits (NUCLEO-F401RE + SX1272MB2xAS) with my SW.
Connect the KITs to the PC and open a terminal emulation (for example TeraTerm).
The TeraTerm configurations are shown below.
8 bit data
1 bit stop
no flow control
On the TeraTerm you see the link informations. See below.
the NUCLEO-F401RE, if all is OK, you must see the GREEN led that
flashing quickly. This means that the two KITs are working properly.
If the GREEN led flash slowly means that is not present the link between the two KITs.
