A movable cccd_handle feast. What am I doing wrong?

While waiting for a fix I decided to pursue the workaround Chris wrote about 3 years ago here https://devzone.nordicsemi.com/f/nordic-q-a/10332/how-to-use-new-ble_nus_c-module-for-multiple-connections

It's great but it's not a fix because the workaround doesn't support unique data streams and doesn't play nicely with peer manager (one has to rate limit bonding with the workaround) but it's better than a slap in the face.

Better yet, a dropbox?

Ugh there goes a day.

Yeah I went back and didn't see them there either. Drag and drop isn't intuitive when it doesn't work. is thee an email I can use until I can persuade the thing to eat my zip?

I couldn't find the zip file in the private ticket.

And it's probably become evident that the projects are for IAR 8.20.2 and s132 6.1...

What's amazing is the central's sd is populating the handles correctly for all of the service instances (as inspection of sd_ble_gatts_characteristic_add() shows).

If you haven't given up already I did upload the file to a private ticket number 217050

Sorry for the hassle

Thanks Simon.I prepared a .zip and confirmed the issue can be reproduced with three nrf52dks.I added dummy code so there'd be data in place of what my external devices sends to the central. You don't have the custom board with 52832 talking to a funky LCD panel so please make sure to have RTT logging ready - I have what I think are useful if not too verbose logging for the central and periphs.

If everything were working correctly the RTT log on both periphs will show the same messages. But you'll notice only one of them works, the first one to connect.

The zip includes SDK15.2 because my stuff are subdirectories within the SDK.

The central unzips to: C:\nRF5_SDK_15.2.0_9412b96\southwire\surgeguard\sg_xtralev\surgeguard_cent_and_periph

The periph to C:\nRF5_SDK_15.2.0_9412b96\southwire\surgeguard\surgeguard_remdisp

I will need a few minutes to figure out how to privately attach the .zip

Thank you!!

I have taken a look at your problem, but haven't been able to find a solution. If you uploaded the code (for both the central and the peripherals) in zipped format I might be able to figure it out, otherwise I will ask somebody with more knowledge about this than me.

Best regards, Simon
