Anyway i have to tell you about code.

My code is work properly confirm by another board. Same binary download to another board. My another board using rev.3 chip with package is QFN(QFAAH00(0x0072)) is work fine.(32khz xtal, 16mxtal and antenna part is different current board... another board not use balun and chip antenna. use pcb antenna.)

thanks for your kindness.

@wooseok: Could you capture again a trace that has the following:

You device advertises
MCP on PC get connected (with the dongle)
Disconnect MCP on PC, then use nRF MCP on Android to try to connect

After that, in Wireshark, click File -> Save and save the trace as .pcapng file. There is more information in the pcapng than the .txt file.

I suspecting there could be something wrong with the 32kHz crystal. Could you send me the BOM of your board, also layout if possible. Could you send me the source code of the project you are testing with, it could be the SDK's example that you modified to test on your board ?

Thanks reply Hung.

trace data is just text data. please open your notepad or just you got a text editor(even keil editor). and that data is export from nordic rnf sniffer and wireshark. trace data export in wireshark [file -> export packet dissections -> as "Plain Text" file...]

And I already change example project. ram size to 16kB(0x6000 -> 0x2000) in keil project option(Read/Write memory areas). please refer upper add image in post.

and ios and android scan using nordic's app (Master Control Panel v3.4.1).

Hi wooseok,

Which software I should use to open your sniffer trace data ? If possible please capture a trace with our sniffer.

Your rev 3 chip is with 16kB RAM, you may need to modify the project setting of the SDK examples because they were made for the nRF51422 QFAC which has 32kB RAM.

Which app did you use on iOS and Android to scan for devices ? Have you tried the nRF Master Control Panel app on Android ?
