ble_nus_c: the received packet is only 1 byte long while I send more than 1 byte

[Phan_hai_hust]

Hi nordic,

I send multiple bytes but always only receive packets of length = 1. For example in the picture, I sent 2 bytes 0x68, 0x69 ('DE') but only received the first value ('D'). I did not intentionally change the code of the file: ble_nus_c.h / .c (add only one line log_info as shown in the picture).
Maybe I accidentally fixed something that I didn't know. Please help me solve this problem.

I attached the link containing the file: ble_nus_c.h / c

sdk: 15.3.0

How are you sending?

I use an android: ble peripheral simulation app. This application I have used many times, it makes sure to properly simulate 1 real peripheral. (I used this application for blinky peripheral simulation and can transmit data with nrf Connect).
The last line of the image is a packet (2 bytes) I send and ble_us_c still only receives 1 byte.
I have checked the contents of the file ble_nus_c.h / c has not been changed. So infer, maybe my main file has a problem. I am checking, but if you have any suggestions on how to find the error, please hear from me.
