SPWF01SA.11
(Wi-Fi module)
Flow description
Put jumper on JP3 as in the picture (pulling high (3.3V) BOOT0 pin signals “firmware download” mode)
Run the Flash Loader Demonstrator (UART Baud rate )
Specify the as starting address. ATTENTION! BE CAREFUL TO SPECIFY THE RIGHT ADDRESS
Specify the file to be downloaded (i.e SPWF01S f58d6b-RELEASE-main.bin)
Follow the steps (default) until the end of the process - see step by step guide on the next page
Remove jumper from JP3 (Pull low (GND) BOOT0 pin)
Reset the dongle
Open a terminal emulator (Baud rate: / Data: 8 bit / Parity: none / Stop: 1 bit / Flow control: none) and restore default settings typing AT command in brackets (AT&F)
