Why send AT command device not respones?


  • administrators

    Many users using the AT command, the first time you send a command, always find yourself sending commands without any response. Here to share with you to send the command should pay attention to the issue.

    In the RAK all products that support the AT command in the document will have this introduction:
    0_1515548600245_upload-2c491860-b98d-448c-8cd6-b5463373080c
    Perhaps many users did not notice this sentence, you may not understand its meaning, here to fully explain the meaning of the following sentence:

    1. If you are using MCU to write code control device, then you need to send the command is "at+version\r\n".like this:
      0_1515549151348_upload-f24c8525-fe29-4013-81a6-8b0a0b6c7ec3

    2. If you are using serial port tools on your PC to send in ASCII, you should send "at+versionENTER".like this:
      0_1515565872313_upload-b045f0b8-76da-4109-8c5f-4391e42a0fd4

    3. If you are using serial port tools on your PC to send in HEX,you should send "61 74 2B 76 65 72 73 69 6F 6E 0D 0A".like this:
      0_1515549730130_upload-e4be7f78-b20d-403d-9a2f-f80893082854
