BLE Notification not confirmed on Android

[A_Caron]

Hi,

I'm working on an application with S130 central (client) connecting to an Android peripheral device (server). I have two characteristics on peripheral device, one for write and one for notify. I can successfully register on notification and write multiples packets in request mode but I only receive one packet by notify in response.

I try to debug using an other android device with the nRF Master Control Panel Application and it works with it, I receive all packets.

On android, after each packet sent to notify I should be called back by the function onNotificationSent, It's the case when I'm using the nRF MCP app but with the S130 device onNotificationSent is never fired.

Thanks a lot for your help
