Glad you worked it out :)

[quote user="DmitrySol"]Very rarely I observe another problem.
Playing audio in the car through the same phone over bluetooth is breaking.
Audio plays a litle time, than pause a few seconds is followed. and it is repeated.[/quote]

Is this related to your original issue? If not, could you create a new ticket for this.

The issue was caused by not optimised working of spi slave.
Host mcu had large intervals between bytes.
After optimising spi master the issue was disappeared.
It is strange enough. But now it works correctly.

Hi,

Sorry for the late response.

I think this might be related to caching on the phone. Which phone are you using? Android or iOS?

It seems to work fine except for when you use it in the car. Is it a lot other wireless devices(Or something else) nearby that might disrupt the connection?

Software re enable of bluetooth on phone helps to reestablish good connection.

by using:
bluetoothAdapter.disable();
bluetoothAdapter.enable();

But It is not good idea.
All bluetooth connections will be reset. :(
(for example audio over bluetooth will be switched off)

Hi.

Issue is actual still.

I try to understand it.

It has following view:
Device as central works with phone as peripheral. (Details about sdk and family of chip are in previous post)
Working is stable. It can be many hours so.
Disconnections and reconnections are working fine.
But if I use system in the car, Issue is showed in few minutes.

Connection is dismounting.
Central make new attempt to connect at once. (I tried to pause there. It doesn't help.)
But connections are failed every time.

Restarting of central device doesn't help.
Restarting of phone application doesn't help too.

New good connection is available after re switching Bluetooth on phone only.

Logs on device side and phone side:

phone side:

Errors can be different sometimes.
In this log are two cases of errors.

In additional:
When issue is there, if I connect another peripheral chip as another central, it works correctly in the same time with the same phone.

RE: a little timeout between closing and new connection

DmitrySol — Mon, 07 Dec 2020 04:31:07 GMT

NRF52832 is used as central for connecting with phones as peripheral.
NUS service is used. Lesc is used too.

SDK 17.0.0
SoftDevice S132 V7.0.1

Board is our.

Application for phone is our.

It seems to me now that problem is in our application for phone.

Because restarting of central doesn't help.
Removal of phone doesn't help too (In previous message i was wrong)

Connect established after off/on bluetooth on phone only.

I'll try look in the application now.

Sorry for worry.

Thanks

Hi,

The following information will be helpful:

Which SDK and Softdevice version are you using?

Are you using a DK or a custom board?

Which example are you running? Have you done any modifications to the example?

Which Phone are you using?

Which App are you using to connect the phone as peripheral? Are you using our nRF Connect app?
