I tried to use your files in the hrs_freertos example from SDK15.2 and was stuck in the loop of missing headers. That is the reason I asked you to give me the project files also. The main.c and the config files were helpful but including your project files would also save me tons of time trying to build a project.

If the nRF Connect APP is used to test ble devcie? It need to obtain data just as follows:

Then switching between cell phones,each phone need obtain data.

This demo has another problem is that I can't delete bonding message by pressing button.Can you delete bonding message?

Ah, OK. For some reason the android phone app is not responding to the security request made by peripheral. I did my testing using nrf connect for desktop which works like a charm. For some reason the nrf connect on android does not respond to your device security procedure.

Can you see if your program works well with nrf connect desktop? you would need a spare DK for that.

Thank you very much for your reply.

I've never used nrf connect desktop,because my ble device will connect to cell phone in most cases.

Just like you say,problem caused by Android OS which may be incompatible with nordic ble device,If there is any way for me to solve the problem?

I think there is some problem with Android App version of nRF connect. I have not looked into the sniffer log of this, but I am quite positive that the nRF Connect on Android version is behaving differently than the desktop version, and a sniffer trace should reveal all secrets. I do not think your program is doing anything wrong. If testing with phone version of nrf connect is important for your product then please check the sniffer log of why the bonding fails.
