STM32 Nucleo Programming Warning
Preliminary samples of X-NUCLEO-IDW01M1 mount R21 zero-ohm resistor which may interfere with JTAG programming of STM32 on STM32Nucleo board.
Disassemble R21 to fix the problem.

The X-NUCLEO-IDW01M1 is a Wi-Fi evaluation board based on the SPWF01SA module, which expands the STM32 Nucleo boards.
The CE, IC and FCC certified SPWF01SA module has an embedded STM32 MCU, a low-power Wi-Fi b/g/n SoC with integrated power amplifier and power management and an SMD antenna. The SPWF01SA module is also equipped with 1 MByte of external FLASH for firmware update over-the-air (FOTA).
The firmware features a complete software IP stack to open up to 8 TCP/UDP sockets, as well as dynamic web pages with SSI to interact with the module and a REST API (get & post) for conveniently transferring files to/from servers in the cloud. The module can simultaneously behave as a socket server and socket client. The firmware supports secure sockets with TLS/SSL encryption, ensuring secure end-to-end communications with the cloud, with or without authentication. The module operates as a client STA, IBSS, or miniAP (with up to 5 client STAs).
The X-NUCLEO-IDW01M1 interfaces with the MCU on the STM32 Nucleo board via the UART serial port; the user can easily access the stack functions using the AT command. X-NUCLEO-IDW01M1 is compatible with both the ST morpho and Arduino UNO R3 connector layout.
- X-NUCLEO-IDW01M1 hosts FCC, IC and CE certified SPWF01SA module (FCC ID: VRA-SG9011203, IC: 7420A-SG9011203 and ETSI compliant)
