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.
Also please note that on page 63 of the DA1469x datasheet (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：
两个HW修改已经被应用-house for all delivered DA14695 Wireless Ranging DKs. Please see section 4.1 in the user guide.
