send data from msp430

[Kaito]

Now i try to send many data from external device. I can send it for 4 times. But after that,the device will be disconnection. I used analog discovery and I was able to confirm that the data is coming. I want to solve the problem,but I don't know what is cause.

thank you in advanced

According to these post here and here , this could be caused by hardware issues with BLE on the iPhone 6.

A workaround is to set your LFCLK accuracy to 250ppm. For SDK 14, this is done in sdk_config.h like this:

Let me know if this solves the problem for you.
