你好
I have two DA14695-00HQDEVKT-U kits and have loaded the WiRa ranging sample app from the WiRa SDK.
我没有mikrobus显示，但这没关系，因为我已经定义了从构建中出来的。
I have the two devices connected to terminal emulators and I can see the outputs on power up.
When I have the default power setting :- 5V from VBUS J2:pin2-3 I can see the initiator connect to the responder and I see the distance being shown.
Wonderful.
这一切都被关押在我的电脑上。
So I thought let me now power the responder via J3:pin1-2 so that there is power on the VBAT pin of rh 14695 and obviously 0v on VBUS because there is no jumper on J2.
I was expecting to see the initiator to connect to the responder and show me some range readings --不工作。
（我强调，发起者刚刚显示“未找到外围设备”）
Which means if I were to power the responder from a battery it is not going to work. Therefore I cannot perform any range test in open space outside over a longer range than just the 1.5m I can do on my desk.
I have not modified the firmware to operate 'in battery mode' as I see no documentation that I need to do that.
是否是响应者中的记录器正在阻止的情况，因为UART缓冲区已满？
期待收到某人的回复。
谢谢你。
More on this.
I have undefined CONFIG_RETARGET in the responder and and if power from VBUS it works (though to logs to terminal emulator as expected)
如果我然后移动跳线J3：PIN1-2然后启动器只是报告“未找到的外围设备”
I will be most grateful for a detailed explanation of how to get my WiRa ranging to work so that
(1) Initiator is plugged into my laptop and will log the range data as I can currently see
（2）响应者由J3：PIN1-2供电，并插入电话USB Power Bank
（3）然后最后，它使用连接到3.3V电池和J3：PIN2-3的响应者
期待着你的眉头。
More on this.
With the jumper on J3:pin1-2 and when I plug it into my PC it all works.
如果我拔下插头然后插入墙壁USB充电器，它就没有。
吸烟枪可以从Segger芯片复位到14695。
Thoughts?
并且我可以确认，当从USB充电器PIN 2供电时，J3上的电源是3.3V，确认VBAT具有电源，但是I VBUS具有0V但VBUS_OUT（如UM-B-103中的图5也显然为5V）。
Hence only difference between plugging into wall charger and a laptop is that the segger chip and USB hub is poweredand由PC驱动。
更多反馈。
With the device plugged into a PC the segger chip is being driven and RSTn line (Which is RESETn of 16495) is at 1.08V
通过从墙壁充电器供电的装置，RSTN为0.42V
我认为重置线有问题，也许需要一个更强大的上拉，以确保重置坐在芯片的电源轨附近。
数据表（表9）垫_RESET, the HIGH level shall be a minimum of 0.7*1.2v= 0.84 and for low the max should be 0.3*1.2=0.36
我测量0.42，所以高于0.36，所以它恢复看起来看起来不像吸烟枪
在一个巡回赛后，我可以让它工作。
I shorted T_RESET which is on the other end of D9 to 3.3v and it fires up and I can see measurements at the initiator end.
因此，我更换了3k3上拉电阻，使得当Segger芯片未被PC驱动时，T_Reset很高，并且根据PDF中的附带的照片也适用。
你好MTAILOR.,
感谢您的问题和您的研究结果。所以。如果我理解正确，如果DA14695 USB套件通过电池电源，则存在问题。根据用户手册，您可以从外部Lipo电池（连接到J5标题）提供3.6 V至4.3 V至VBAT引脚，当跳线放置到J3（引脚2-3）。请参阅用户手册中的第5.19节电源选择标题，以检查应如何连接电池以及跳线的配置应如何。还请在当前部分查看注1。请问您是否已使用此配置？
谢谢，PM_DIALOG.
你好
谢谢for coming back to me.
现在你提到它，我没有用电池供电电路板。
但是，我将手机电池组连接到USB连接器J1，以便通过LDO（U2），我获得3.3V，通过J3馈送到VBAT（并且还确保J2上没有跳线）。我确实如此，因为它更容易将手机电池组连接到USB连接器。
Hence according to Figure 5 in UM-B-103, I was feeding VLDO into VBAT and that requires the pullup resistor.
我没有仅仅因为2 AA（或AAA）电池给我而向VBAT喂食3.6至4.3V至VBAT3.0v和3 AA（或AAA）电池给我4.5vand both 3.0v and 4.5v are outside the spec you and the user guide UM-B-103 mentions.
Can you please describe what type of battery you have used to get between 3.6 and 4.3v? That is an unusual range.
Actually given I can make it work by feeding 3.3v via VLDO and it works, surely the VBAT spec should not be 3.6 and upwards because 3.3 clearly works.
还请注意,DA1469x da的63页tasheet (CFR0011-120-00) you have VBAT1=VBAT2=3.0v.
在UM-B-103和VBAT系列中，我真的是在没有标号的情况下，不应将3.6V或4.3V表示为3.6V或2.6V至4.3V
谢谢
Look forward to hearing from you.
你好MTAILOR.,
我为我迟到的回复道歉。说实话，我有点困惑 - 你能澄清DK的问题是什么？
通常，您可以使用USB（5 V），LDO（3.3 V）或外部电池作为电源。您可以使用外部Lipo电池（可选）3.6 V至4.3 V。
Thanks for your indication – I’ll evaluate this. Feedback would be more than welcome,
谢谢，PM_DIALOG.
你好MTAILOR.,
由于您使用的是DA14695-00HQDEVKT-U，您应该执行以下HW修改：
HW修改都已应用于所有交付的DA14695无线测距DKS。请参阅“用户指南”中的第4.1节。
谢谢，PM_DIALOG.
