In addition to this the examples are implemented to work with the normal UART communication. Avoid using printf() directly to prevent blocking the BLE stack or interfering with timing-sensitive operations.</P> <P>&nbsp;</P> <P>Best Regards</P> <P>Luis</P> Mon, 06 Oct 2025 21:40:29 GMT luis_maravilla 2025-10-06T21:40:29Z https://community.nxp.com/t5/MCX-Microcontrollers/KW45-printf/m-p/2180672#M4146 <P>Hi Nxp team,<BR />i am using KW45 EATT example code and i wanted to use debug console.</P><P>i am able to use shell_write() to print data in tera term but i am not able to use printf() in EATT example.</P><P>please let us know what changes we have to do to use printf() to print data.</P><P>please provide if any example code or document to use printf().</P><P>Thank you!</P> Mon, 06 Oct 2025 16:00:52 GMT https://community.nxp.com/t5/MCX-Microcontrollers/KW45-printf/m-p/2180672#M4146 Chan_17 2025-10-06T16:00:52Z https://community.nxp.com/t5/MCX-Microcontrollers/KW45-printf/m-p/2180816#M4150 <P>Hello</P> <P>To work with a Wireless MCU, the connectivity software implements its own serial manager divers, it doesn’t use the SDK debug console and therefore it doesn’t use the semihosting debug console.
