Disconnect on S130 v2, HCI Error 0x2A

[gabitoyacu]

Hello,

I've an issue with several smart-phone models when I use the softdevice S130 v2

I did tests with PCA10028 and the example "ble_app_bps".

I used softdevice S110, S130 V1, S130 V2.0.0, S130 V2.0.1

This work well with S110 and S130 V1, but this fails with S120 V2.x

When I connect with the smartphone inmediately the PCA10028 report a disconnect reason = 0x2A. This happens with some smarthphone, for example, Samsung Galaxy J1 ACE.

I need use the version S130 because our device has to connect to a smartphone and other peripherals simultaneously.

Could you help me? Do you have any idea about this issue?

Thanks & regards

It's pretty rare to see BLE_HCI_DIFFERENT_TRANSACTION_COLLISION (0x2A). There is smth wrong with the link layer. We would need to have a sniffer trace to really tell what happened.

Could you provide one ?

Which other phones did you test with ?

Do you see the problem when you test with other examples ?

I don't have any trace, my kit doesn't work with sniffer firmware. I've done tests with our hardware (I've manufactured prototypes) and our firmware, but the problem persists.

The S130 V2.x works with samsung note, motorola moto x

I'll try to use our hardware as sniffer.

Look at files s130_v2_fail.pcapng & s110_ok.pcapng. These are with the same smart-phone

@gabitoyacu: The sniffer is not complete, only 3-4 packets in the trace. Did you modify it or smth ? It should include advertising packets, and other data packets when in connection. Please try again
