Hi All,
I replaced the DA14583 chip on my pcb because it's OTP memory was flashed. After reconnecting it to an UART -> usb connector using P0.6 and P0.7 I noticed that the chip is sending out bytes:
00 fc 00 fe 00 fc 00 fe 00 fc 00 fc 00 fc 00 fc
I'm trying to flash it using my self writting uart flashing tool but I the uart output from the chip is not what I expected (0x02).
Can someone explain what this is and what I can do to write my binary to RAM?
Cheers,
Reinier

嗨ReinierH,
Could you please try to use the flash programmer of SmartSnippets toolbox in order to program the SPI Flash? We strongly recommend the usage of the SmartSnippets toolbox in order to program the SPI Flash? After that, are you getting the same bytes? With the usage of the power profiler of the toolbox, please check if the device is advertising correctly. Also, if you download the firmware into the System-RAM, is the device working as expected? Which baud rate are you using tin the serial monitor?
Thanks, PM_Dialog
