How to make 'without response' in nus rx characteristic?

Manuel Kwong

Hi,

In my application, I am using nus service with S110 V7.1.0 (nRF51822). I faced to one problem that the rx channel is set up to notify characteristic. In iOS (8.3), it is often blocked when it sends out data to the nus channel to the device.

The tx channel in the device has no problem and very smooth even the data rate is boosted to very high. However, in the rx channel, it cannot receive the data sometime and the whole communication is blocked up. The Bluetooth stack returns timeout error when iOS apps wants to send out data to the device via the nus rx channel (device).

In the tx channel,it is set to write without response but in rx channel, it is set to notify.

Question : can the rx channel be set up to be without response so that it is much more smooth?

    Hi there,

    Notifications and Write without Response follow the exact same flow control mechanisms, so the speed should be roughly the same.

    I am not sure what is going on here, maybe someone from the SDK team will be able to take a look.
