Hi,

log from peripheral B, using DK52833 A as central, looks like it worked as expected.

Did you press Button 1 on both devices to confirm the passkey value used for bonding when peripheral A and C connected?

Could you try to erase DK52833 A and program again before connecting peripheral C? Does peripheral C work as expected? If not, provide a sniffer log.

because we are working for a robot charging automation project, static address makes more sense. and it's eaiser for the debuging.

Hi,

[quote user=""]-CONFIG_BT_PRIVACY=y

May I know why you disable CONFIG_BT_PRIVACY on the central? What would you want to test and achieve?

Enabling the CONFIG_BT_PRIVACY Kconfig option would make the device use Resolvable Private Addresses (RPAs) by default as the phone.
