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

i tried the debugging,but i didn't know where change. The point I changed is the following source code. gyazo.com/613e72f4b57cf278136df2b2efe76197 If you change this way, the connection will be lost even if the test data came.

now I am controlling without flow control. Do I have to adjust clocks?

Please tell me if someone understands this problem!!! I found that this problem occurs when data is being transmitted. When data transmission is interrupted, ble becomes connectable, and blank data was transmitted when connecting. Do I have to add processing like interrupt handling when sending data on the program?

regards!!
