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

Thanks.

I note that it says,

"This is an Android application that allow developer configure a BLE peripheral simulator. The application allow to profile multiple peripheral simulators. Possibility customization characteristic's handler, this would help you to build enough complexity simulator serve your software"

So it sounds rather like it's a basis for you to work from - rather than a complete & ready-to-use solution?

But what application was it?

Give a link!

Sending a single byte at a time is not "wrong" or "bad" as such - as with any tool, you have to understand what it does and how to use it.

nRF Connect can act as an 'Advertiser', if you run it on a suitable device. Never tried it myself, though.

Due to the above application, I will not trust non-popular applications :) . I tried to borrow another set to check. If you know any reliable peripheral simulation applications, can you suggest me :)

Thanks for explaining.

So, for completeness, what application were you using?

The real problem is not because of my code, but the Android application I use: in fact, it only sends 1 byte while still logging out as multiple bytes. It's hard to understand because I used this application to transmit data normally. :) :)
Thank you for your suggestions, helped me find the problem faster. Thanks very much.

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.

How are you sending?
