Hi Dialog member,
Curently I develop module using UGMZ2AA+MCU STM32. I download the HEX file to UGMZ2AA through JTAG direct boot from PC. I can download the HEX file to the UGMZ2AA. Advertise name appear on the LightBlue application but during attempt to connect I facing connection alert as attach picture and can not make any connection with UGMZ2AA. Could you advise me what is the possible condition that could make this alert happen?
