Heart Rate Collector Multilink Capabilities

[All4here]

hello i am using nrf 52840 board with sdk 13.

i use heart rate collector example to connect the 6 heart rate peripheral . Modified the hrc_c example following this link

Heart rate client start working on multi link.

when i connect the first peripheral, everything was working. when try to connect the second peripheral, he just connect and after timeout about 4 second then disconnect and again connect and disconnect and so on .. but this has no effect on the first connection, first connection was stable. only happening with the second connection. he give me the disconnect reason 0x22. i read little bit in the forum then i realize, may be because of the peer manager. then i also remove the peer manager on the client side and also on the peripheral side but still same error.

i also copy the data from the sniffer with peer manager active. test2.pcapng

any guide will be appreciated,

thank you

Hi,

Have you tried debugging ? Please see this post on how to debug

i have no error in the code. i am only getting the BLE_GAP_EVT_DISCONNECTED Events on the both side means Central and peripheral. disconnect reason is 0x22 = 34 , no idea how i can manage this ..

[Sigurd]

0x22 is BLE_HCI_STATUS_CODE_LMP_RESPONSE_TIMEOUT.

do you get this when you remove the peer manger also?

There is also some "Error code: PIN or Key Missing (0x06)" in the sniffer log. I'm not seeing any disconnect event in the log, in the last entry in the log, the devices are still connected.
