DSPS Android version not showing the device number

Hi PM_Dialog,

1.使用iOS DSP移动应用程序时是否能够连接到平移？

是的。我能够连接设备。此外，我也可以通过这个应用程序发送一些数据。喜欢一些字母数字。我可以在串行终端上看到它们。

The DSPS mobile application is available for Android devices, so it is little bit weird that you cannot see your device

No. I can see the device in Android also.

另外，你的意思是什么意思是“序列号”？

我的意思是设备的序列号祝福。在iOS应用程序I can see something like A92B3191-3A43-F4ED-ADFC-67 and so on. I thought this is the serial number of the BLE device. This information I dont see in Android. If this is something else, Is there any way to see the serial number of the device in the android app.?.

2.Did you use the iOS or the Android DSPS mobile application? In your custom board, I suppose that you are using the PAN, don’t you?

I have both apps iOS and android. In iOS if i enter 100 alphabets in the app, I can see up to 50 in the serial terminal. In Android it is even less.

yes I am using PAN in my custom board.

Could you please let me know if in the DSPS device source code, you are using the extended sleep mode?

Yes it is in extended sleep mode.

const static sleep_state_t app_default_sleep_mode = ARCH_EXT_SLEEP_ON;

3.If your question is regarding the BLE stack. Otherwise, please clarify it.

我会在某个时候澄清它。我应该从我的经理获得澄清。谢谢你。

Hi PM_Dialog,

1. Here Im attaching the screenshot. I can see the device name and some other information(subscript) which i did not understnad. It is showing the name DIALOG-SPS. My requirement is to display some number like CL820-xxxx so that we can identify the product. Previously we have some devices with serial number CL820-xxxx. So this project will be the next version to them. We can easily understand. Sorry for my wrong communication. I was also thought to display the serial number of BLE. But our manager intension is to display our product number instead of DIALOG-SPS.

2. I am using 115200. Also I have tried with other Baudrates. Only partial data is displaying with PAN1740 USB dongle.

当我使用我的客户端，没有数据正在传输。在代码中，我改变了延长的睡眠才能睡觉。仍然没有变化。

I did not use any UART flow control. I have just read that document. I will use UART flow control.

If I use UART Software flow control, can i have the code snippet pls?.

If I use UART Hardware flow control, I should only connect the hardware like Rx,Tx,CTS and RTS or should I do any other things?.

3.Today I was trying to pair the PC to my custom board. I am able to see the device on PC(DIALOG-SPS). When ever I try to pair /connect them, It says connecting for some time and then try to connect again. I have attached the image.

How can I do this?. UART flow control is the solution also for this?. Thank you.

Hi PM_Dialog,

1. Thank you.

2.Since you are using extended sleep mode, you need to have hardware flow control and the CTS/RTS/TX/RX pins should be connected.

If I use ARCH_SLEEP_OFF. Then also I should use Hardware/Software flow controls.

I have some interface / connection doubts.

For example>

I would like to implement the Software floe control.

I have connected my DA14850 device to the MSP432 EXP Breakout board. The MSP breakout board has two parts one is debugger part and another is Microcontroller part. I have connected SWDIO ,SWDCLK pins of DA14850 to the SWDIO ,SWDCLK pins of Debugger and also RXD a,TXD pins of DA14850 to the RXD ,TXD pins of Debugger part.

当我尝试刷新sps_device代码时，它会说RDDI-DAP错误。如何将DA14850引脚的RXD和TXD引脚连接到MCU？或调试器部分？

If I want to have Hardware Flow Control:

Can I connect the pins like below:

#define gpio_uart1_tx_port gpio_port_0.
#define GPIO_UART1_TX_PIN GPIO_PIN_4
#define GPIO_UART1_RX_PORT GPIO_PORT_0
#define GPIO_UART1_RX_PIN GPIO_PIN_5
#define GPIO_UART1_RTS_PORT GPIO_PORT_0
#define gpio_uart1_rts_pin gpio_pin_3.
#define GPIO_UART1_CTS_PORT GPIO_PORT_0
#define GPIO_UART1_CTS_PIN GPIO_PIN_2

3.当我试着运行中的设备调试ode, it is trying to recover the debug connection. And also written there that the device might went in to dep sleep mode and application could not come out of it. The device at this moment is ARCH_EXT_SLEEP_ON.

当我将其更改为arch_deep_sleep_on时。我甚至不在蓝牙列表中看到设备。

When I used ARCH_SLEEP_OFF then I can see the device like ARCH_EXT_SLEEP_ON. In these both cases I am unable to pair device. Please help me out this situation.

Flow control is the reason for this also. Thank you.

Hi PM_Dialog,

Here I am not using the MCU. I am using the Debugger part of the developemnt board.

1. I just wanted to pair the BLE to my PC. I am not using the sleep mode.

我改变了这条线

const static sleep_state_t app_default_sleep_mode = ARCH_SLEEP_OFF;

我也没有使用UART。我刚刚将Pan1740的SWD引脚连接到调试器的SWD引脚。在我开始和停止在Keil调试后，我试图在PC上连接BLE。它正试图连接和推动一段时间它说尝试连接您的设备。

问题是什么。为什么它不配对。该设备不在睡眠模式下。

2. Other side I tried the software flow control , On the debugger section I have pins for SWD and RXD,TXD. I have connected RXD and TXD pins of PAN1740 to TXD and RXD pins of debugger part respectively.

Then the code is not running. The keil shows RDDI-DAP error.

我无法配对设备。如果我这样做，那么我会尝试进行通信（软件调试）。

Hi PM_Dialog,

1. “I am using the Debugger part of the development board.” : The SWD is been using for debug purposes. You could download firmware into the Syst-RAM as well. Could you please clarify what do you mean with that?

是的。I am downloading the firmware to Sys-RAM via SWD. My intension to say Im using only debugger part is that Im not using the MCU part of the development board (MSP-EXP432P401R). Here my doubt was, Should I use MCU part to download the firmware to BLE_ or can I use only debugger part to download the firmware?.

I have got the answer. I no need to use the MCU on development board.

2.“I just wanted to pair the BLE to my PC.” I need some clarifications on that. Are you using a PC application?

Here Im not using any PC application. On the PC for example. If I want to use my phone via bluetooth, first we need to pair the device by entering some password. Then they will be paired and available for file or data sharing. This is waht my question was.

在阅读我们的论坛后，我也几乎得到了答案。我应该使用ble_app_security项目与PC配对。我已经做了。在这里，我的努力是在我的PC和BLE之间进行串行通信。首先，我们需要将设备配对，然后我们应该进行串行通信。

“我也没有使用UART。我刚刚将Pan1740的SWD引脚连接到调试器的SWD引脚“：这是错误的，因为DSP正在使用UART

这也是我的错误。我从我们应该使用BLE_APP_Security项目的论坛中了解，然后必须在项目中实现UART功能，以在Teraterm串行Termianl上进行串行通信。在这里，我问你是对的吗？我们有没有BLE的项目可以进行串行通信吗？

4.“Other side I tried the software flow control , On the debugger section I have pins for SWD and RXD,TXD. I have connected RXD and TXD pins of PAN1740 to TXD and RXD pins of debugger part respectively.” ; This is not software flow control! The SW flow control is a software implementation of HW flow control and instead of CTS/RTS you will have XOF/XON.

ble_app_security with UART also need software implementation of hardware flow control?. I dont see those macros in user_peripheral.h file. Also one doubt that earlier you mentioned that for software flow control we just need to have RXD and TXD connections and device must not be n sleep mode also we must change the macros from HW to SW in user_peripheral.h file. Then it automatically makes the communication in software implementation of HW flow control. Am i right?.

5.“Then the code is not running. The keil shows RDDI-DAP error.” : Could you please send me a screenshot?

I still see this error. When I connect only SWD pins I can able download the firmware to Sys-Ram . Additionally when I connect RXD and TXD pins to have serial communication then I see this RDDI DAP error in the keil. I have also asked in some other forums. One guy asked me to use level shifter if the logic level of MCU and BLE or different. Does it make any sens?. Do you think the logic level of BLE is different?. When i measured the logic level at RXD pin of debugger(without connecting the ble), I see 3.3V.

Im stuck here at serial communication. Im also attaching the screenshot. Please find it. Thank you.

Dear PM_Dialog,

先前我以前用于SPS_DEVICE项目。当我发现这个项目时，我们只能与DSPS应用程序通信，然后我切换到BLE_APP_SECURY。我当前的任务是测试BLE和PC（TERATERM终端）之间的串行通信。

Can we test serial communication on sps_device project?. You said I should implement flow control to have serial communication. You also said for ble_app_security project I dont need flow control.

因此，我正在使用ble_app_security项目。我在最近一天说过所有修改。

like

#define CFG_PRINTF in the da1458x_config_basic.h

Change the uart ports of the fw and assign the UART_TX port/pin to P04 and UART_RX port/pin to P05 (make sure that the configuration that you have changed is under the HW_CONFIG_PRO_DK and that this the board declared in the HW_CONFIG definition).

调用ARCH_PRINTF（）函数以打印例如设备启动广告时。

Include the arch_console.h file.

However I do not see message on serial terminal. I have an error when I made debug on keil. that error is

*** error 122, line 17: AGDI: memory read failed (0x000000C6)

I have also attached the screenshot. Can you say me the soluton for this error.

I dont see that error for sps_device project. If I make above mentioned procedure for sps_device project, Can i see the serial data?. Thank you.
