Notification problem on nRF51

[Raj]

Hi all, I'm working on sdk11.0.0 and s130 softdevice. In my project I need to take data from sensor board through uart and send to mobile through ble for every 500ms. Sensor board send 60bytes of data in a single string with baud rate a 115200 for every 500ms and I need collect those data and update to mobile through notifications.

I started the timer for 18ms(time required to fill rx buffer i.e 256 bytes) when I received first byte, in timer event handler I'm reading values from uart and updated to mobile through notifications

sometimes mobile (central) failed to received notifications and I'm using connection interval 15ms and 25ms for high throughput even though some times recentral failed to receive notifications can any one help me to solve these problem

thanks in advance.

Why are you not checking the returned error code of ble_nus_string_send()? How can you know that the procedure is successful?
