Hey everyone! We are having some issues here to build an APP using this device. We are currently using React Native and we actually are able to receive some responses from the device, like the ATI.
The problem becomes when we try to move to the binary mode (AT+BINREQ). We cannot find any example on how to start that mode and start sending data.
At the moment, to receive the correct message from the device, we're writing 'ATI' to the characteristic 914f8fb9-e8cd-411d-b7d1-14594de45425 and reading the version from the characteristic 3bb535aa-50b2-4fbe-aa09-6b06dc59a404.
This is working fine, but when we receive the OK after writing 'AT+BINREQ' we don't actually see any difference in the device.
奇怪的是，设备在使用您的演示应用程序时运用很好。
Is there any trick on how to start a binary commuincation with the device? Would it be enough to write 'AT+BINREQ' and right after receiving the "OK", start sending the data we want?
Hi marksabbath,
Please take a look at the Codeless user guide and section 4. Binary Mode – link is provided below:
http://lpccs-docs.dialog-semiconductor.com/UM-140-DA145x-CodeLess/binarymode.html
Is it a custom board, or it is any of out DKs?
You should hare same hardware setup as shown in Figure 9.
Thanks, PM_Dialog
Hey, thanks for your answer!
We have third party hardware that is using the CodeLess.
As mentioned above, we are able to communicate via AT commands already by the characteristics 914f8fb9-e8cd-411d-b7d1-14594de45425 and 3bb535aa-50b2-4fbe-aa09-6b06dc59a404, where we have sent the command 'ATI' and received the device version name, which seems to be a proof that the communication works.
Still, when sending the AT+BINREQ, we receive only "OK" and nothing else happens. We send some commands to the CodeLess device and it does nothing.
Would it be required to send all those commands that are shown in the video referenced in that link you've sent in order to have the device properly set?
Hi marksabbath,
>>>Still, when sending the AT+BINREQ, we receive only "OK" and nothing else happens. We send some commands to the CodeLess device and it does nothing.
Could you please describe the procedure you are following? Are you send data over UART? Please share more inputs on that. Additionally, what are the UART pins that you are using in your custom board?
Thanks, PM_Dialog
>请你能描述你关注的程序吗？
我们通过蓝牙连接到BLE设备，并使用Android手机和我们的测试应用程序在反应或颤动中。我们可以说它是正确连接的，因为我们通过特征914f8fb9-e8cd-411d-b7d1-14594de45425发送命令'ati'时，我们从特性3bb535aa-50b2-4fbe-aa09-6b06dc59a404读取了值“无附带DA14531 v_6.380.10.4
OK"
>Are you send data over UART?
你的意思是通过另一个特征发送命令吗？目前，我们将“at + binreq”发送到特征914f8fb9-e8cd-411d-b7d1-14594de45425，并在收到“确定”响应后，我们开始通过相同的特征发送二进制数据。我们应该将二进制数据发送给另一个特征吗？
>Additionally, what are the UART pins that you are using in your custom board?
I have no idea. This is a project that an Engineer brought here, and he was able to send data using the demo app that you guys provided.
Hi marksabbath,
Do you have a chance to use a BLE sniffer and share a log file, so that we can understand what is happening over the air?
Thanks, PM_Dialog
Sorry, unfortunately, we couldn't find a sniffer (app) that really works. Do you have any suggestions?
Also, could you please describe what steps (AT commands) that we should send to the device in order to start a binary data flow?
At the moment, we're just connecting to the device and sending the AT+BINREQ. Would it have any sort of initialization process that we would need to do?
Hi marksabbath,
You should have a BLE sniffer tool in order to take a capture over the air.
You should just send the AT+BINREQ command in order to set the device in binary mode. Are you able to execute that command successfully? Can you also to check if the AT command is executed successfully?
Thanks, PM_Dialog
这两个命令是返回“OK”。另外,正如我说的before, the ATI is returning the version of the device, like this: "CodeLess DA14531 v_6.380.10.4 ".
Hi marksabbath,
如用户指南中所述，只能发送AT + BinReq以便在二进制模式下配置无附件。你有任何叫做这件DK吗？您使用的UART引脚是什么？
I would recommend trying to use the SmartConsole application to configure it in binary mode.
