We are using CC3220MODSF12MOBR from many years for our different products, all working fine and we never noticed this issue.
But now, we found this issue for two boards. One board is in customer site and second board is with us only, we kept second board for inhouse Testing/Development.
Initially boards are working fine for 1-2month, suddenly this issue was found.
Once power up the board, Device bootup with the default sate as a AP mode and we are expecting SSID (defined by manufacturer) in our PC or mobile scanner, but PC/Mobile scanner not showing the default SSID.
Note* Other boards are working fine with same scenario/Firmware with same PC/Mobile. So no issue with PC/Mobile/Firmware.
Even we replaced the Antenna with connector from working board, but issue not solved. PCB Tracks is fine with continuity test.
Kindly advise, what is the issue and how we can troubleshoot. Kindly help us we are planning for new production and need to fix this issue.
Thanks and regards,
