Hi
Background:
Initial designed we used microchips RN4871 module and used their UART services. We have mobile phone app that sends screen coordinates when ever movement is detected on screen. The coordinates are received at BLE devices without any latency.
查询
I have setup a mockup using the DA15431 device and using codeless_standalone_531 binary, and using ATrPRINT to send coordinate from mobile app and there is a significant latency. It could be that the ATrPRINT command is also sending +PRINT
Thanks

Hi prakash Solanki,
Thanks for your question and for your interest in our DA14531 BLE solution.
Since you are interested in sending raw data from the mobile phone to the DA4531, you could used the Binary Mode of the CodeLess.
Please see the user guide below :
http://lpccs-docs.dialog-semiconductor.com/UM-140-DA145x-CodeLess/binarymode.html
What is the mobile app that you are using? Is it the SmartConsole?

Hi
Thank you for above answer, I manage to get the BINARY mode to work using the 531_datapump binary file.
For datapump it is advertisng SSID,
I also tried to build the Datapump application and I get following error:

Hi prakash Solanki,
Glad that you managed to get the binary mode work!
Do you mean how to modify the UUID of the characteristics?
The error probably means that you are using the free edition of the Keil IDE which has the limitation for 32KB code. If you need to exceed the 32KB application code, you should purchase full edition.
Thanks, PM_Dialog
With the module programmed with data pump for 51, and module connected to a terminal.
When I use other ble app e.g. lightBlue and connect to device CLv2, on terminal I get following:
+AWAKE
+CONNECTED
But when I use Smartconsole I get following:
+AWAKE
+CONNECTED
+BINARY MODE SUPPORTED
+COMMAND MODE SUPPORTED
How can I enable the
+BINARY MODE SUPPORTED
+COMMAND MODE SUPPORTED
Thanks
Hi prakash Solanki,
The default mode is the “Command Mode”, so your question is how to enable the “Binary Mode” in order to send data to the mobile using the SmartConsole application?
Thanks, PM_Dialog
Yes, I have tried as described in dochttp://lpccs-docs.dialog-semiconductor.com/UM-140-DA145x-CodeLess/binary....
Mobile APP Terminal connected to DA15431
Connects to ble +AWAKE
+CONNECTED
According to doc:http://lpccs-docs.dialog-semiconductor.com/UM-140-DA145x-CodeLess/binary...
<-------------- Send "AT+BINREQ"
Send "AT+BINREQACK" --------------->
How do I enable auto binary mode in my mobile app as achieved in SmartConsole.
Hi prakash Solanki,
Please take a look at section 8.4.6.1. Binary Mode in the user guide.

Hello
I am trying to issue a simple "AT\r" command to the da15431. I am able to communicate to the module via Tera term and able to issue "AT\r" command an I receive "OK". Now I have connected to an MCU and set up correct baud rate and when I issue "AT\r" I get following in the receive buffer from the da15431:
rcvBuffer
0x41 0x54 0x0D 0x0D 0x0A 0x45 0x43 0x30
0x36 0x3A 0x20 0x4E 0x6F 0x6E 0x20 0x41
0x54 0x20 0x63 0x6F 0x6D 0x6D 0x61 0x6E
0x64 0x0D 0x0A 0x0D 0x0A 0x45 0x52 0x52
0x4F 0x52 0x0D 0x0A
In ascii format:
rcvBuffer
A T . . . E C 0 6 :
. N o n . A T . c o
m m a n d . . . . E
R R O R . .
It looks like I am sending correct command AT\r
Thanks
Hi prakash Solanki,
Please let me ask you some questions, so that I can understand the setup
>>Now I have connected to an MCU and set up correct baud rate
Do you meant that the DA14531 is connected to an MCU via a BLE connection or via UART?
In the first case, are you sending the commands from a terminal ?
In the second case, can you please share the UART connections between DA14531 and the MCU? What is the baud rate?
Please share more inputs regarding the setup you are using and the sequence of the AT command, so that I can understand better the problem.
Thanks, PM_Dialog
The Da14531 is connected to MCU via the BLE connection, Baud rate 57600, 8, n, 1 for both cases.
For below setup, I am just sending "AT\r"
MCU DA15431
RX P0_5
TX P0_6
In first case, yes sending command from terminal.
Hello
仅供参考. .我有固定的这样不需要行动。
Thanks
Hi prakash Solanki,
Thanks for the update and glad the you figured this out.
Thanks, PM_Dialog
