Is there anyone familiar with ST's BLUENRG-LP? I would like to ask a question [Copy link]

 

 

I just started to use the BLUENRG-LP chip. When I was looking at the official routines, I found that these three routines seemed to be one program. How should I modify them to achieve master-slave interconnection?

Are there any official routines that can enable the host to automatically send data to the slave, such as transmitting the voltage and temperature sampled by the internal ADC to the slave, and the slave outputs it to the PC through the serial port?

Thank you very much!

ST's BLUENRG-LP chip has been optimized in terms of supporting multi-connection (one-to-many, master-slave integration) features, reaching the industry's leading level. If you want to interconnect, please read the official manual

It is not a program. The server is a peripheral device that can be connected through a mobile phone APP. The client is a role similar to a mobile phone that can connect to the server.

I know that these two programs should be one master and one slave, but the file opened by downloading the official website program is just one program.

I also opened the downloaded BlueNRG-LP DK 1.0.0 and there is only one program.

One project, but corresponding to different contents, a large number of macro definitions are used in the source file, and different functions can be achieved by selecting the corresponding roles.

Thank you, but I only use Keil5 for this one project. I wonder if yours is the same as mine? Do I need to modify some programs?

I have another question for you. One of my boards was working normally before, but after I downloaded the BLE Beacon routine, it can no longer download programs normally. The SWDIO of keil5 shows No target connected. I have tried some methods found on the Internet but still don’t work. I wonder if you have encountered this situation before. Thank you very much for your help.

It may be caused by the chip entering low power mode. Use BlueNRG-LP Navigator to flash another program, or use BlueNRG-X Flasher Utility to erase the program through the serial port.

If there is only JTAG mode, try to connect the RST pin to the emulator correctly.

Thank you very much for your reply. The board I drew only has basic functions, which can be debugged and connected to Bluetooth. The power, ground, SWDIO, SWDCLK, and RSTN are connected for debugging. After connecting with stlink, the method you mentioned did not work.

Thank you very much for your help!

Try a manual reset, such as pressing the reset button, or using tweezers to short RST and GND, then click Erase or Download Program, and release the reset button or remove the tweezers.

Thank you very much for your help! Issue solved! Successfully erased by holding down the reset button and then re-downloaded the program.

Thanks a lot for your help!
