ap-client-two-sdr

[Fei8686]

Hi, Thank you very much for providing this project of openwifi-v1.4.0, it helps a lot during my study. I am experimenting with a zc706_fmcs2 board.The image file I use is “openwifi-1.4.0-notter.img”.

In the app_notes,I noticed that you have proposed a test process related to interconnection with two boards(app_notes/ap-client-two-sdr.md). However, there seems to be a problem with the network.server running on the "client board".

• After the command service network-manager stop,I get the following output on the "client board":

Failed to stop network-manager.service: Unit network-manager.service not loaded.

• Then,I continue to execute the commands provided in the ap-client-two-sdr.md.The following information is displayed on the client side:

  
  root@analog:~#cd openwifi
  root@analog:~/openwifi# ./wgd.sh
  usage:
  Script for load (or download+load) different driver and FPGA img without rebooting
  no  argument: Load .ko driver files and FPGA img (if system_top.bit.bin exist) in current dir with test_mode=0.
  1st argument: If it is a NUMBER, it will be assigned to test_mode. Then load everything from current dir.
  1st argument: If it is a string called "remote", it will download driver/FPGA and load everything.
  - 2nd argument (if exist) is the target directory name for downloading and reloading
  - 3rd argument (if exist) is the value for test_mode
  1st argument: neither NUMBER nor "remote" nor a .tar.gz file, it is regarded as a directory and load everything from it.
  - 2nd argument (if exist) is the value for test_mode
  1st argument: a .tar.gz file, it will be unpacked then load from that unpacked directory
  - 2nd argument (if exist) is the value for test_mode

- This indicates that both AP and client have been successfully started, and the openwifi information of AP can be scanned on the client side, but AP and client cannot be connected.

Could you help me to solve the problem of how to connect with two boards?

Thanks,
The shy

Maybe it is due to that I add password in the hostapd configuration file. You can use this one to replace the hostapd configuration file on board: https://github.com/open-sdr/openwifi/blob/master/user_space/hostapd-openwifi.conf

I have checked the hostapd configuration file(hostapd-openwifi.conf). But the content of the file on board is the same as what you provided.

May I ask if the reason why the board cannot be associated is that the network-manager.service was not successfully loaded? ------------------ 原始邮件 ------------------ 发件人: "open-sdr/openwifi" @.>; 发送时间: 2023年4月7日(星期五) 下午4:24 @.>; @.**@.>; 主题: Re: [open-sdr/openwifi] ap-client-two-sdr (Issue #297)

I have already solved this problem. I replaced the content in the hostapd-openwifi-11ag.conf file to the code you provided, and the two boards were successfully connected.

Thank you so much!
