14681做蓝牙主机时的搜索问题
您好，我想问下在14681下我用ble_gap_scan_start（）这个函数来开始搜索蓝牙设备。我该怎么得到他搜索到的信息呢？有应用到这个API的相关demo吗？谢谢

Chip antenna with DA1468x
Hi,
We're considering using a small chip antenna (Johanson 2450AT07A0100, 50 ohm impedance, return loss 6.5 dB,https://www.johansontechnology.com/datasheets/antennas/2450AT07A0100.pdf) with the DA1468x on our custom board. Do you have any reference designs or documentation regarding using a chip antenna with the DA1468x?
Thank you,
David
3-wire SPI
Hello,
I'd like to use SPI to communicate between the DA1468x and a sensor that only supports 3-wire SPI. The sensor exposes 3 pins: a clock pin, a chip select pin, and a pin used for both data in and data out. How should I set up the DA1468x so I can communicate with this sensor? Can I configure both SPI_DI and SPI_DO on a single GPIO? Or perhaps I should change the configuration of the GPIO and the SPI bus between reads and writes?
Thanks!
David
DA14681 USB_CDC的问题
您好，我在使用1.0.8的usb_cdc的demo时,发现程序应该阻塞在这里的
NumBytesReceived = USBD_CDC_Receive(hInst, usb_cdc_buf, sizeof(usb_cdc_buf), 0);
但是我不给USB发送数据，程序跑了2分10秒的时候。NumBytesReceived 返回为0且一直在while(1)不停的循环，不会再次阻塞在这里。问下这是什么原因呢？
Specifying charging parameters for a battery
Hi,
I'd like to specify charging parameters for a 22 mAh, 4.2V lithium polymer battery. I've been following the guidance in AN-B-035 (Battery Charging), UM-B-056 (Software Developer's Guide, section 10.1 "Enabling the charger"), and UM-B-044 (Software Platform Reference, section 9.5 "Charger configuration"). I have a few questions:
DA14680 Flash memory: Endurance Specification
Hello support team,
I would like to know about DA14680's flash memory: endurance specification.
I can't find its specification in the DA14680's datasheet.
Is it equal to DA14583 specification? (100,000 cycles)?
Regards,
Jun-ichi
IAR Tools
Hello,
IAR工具支持with the DA14680 device or the DA14681 development kit? Is any of the example code done with IAR?
Thanks,

flash size 1M ?
Hello,
I tried to flash a firmware on development kit basic through uart and I get the message : file xxx.bin is too big.
Size of my firmware is 630kB and flash is 1024kB, so I don't understand why it doesn't work.
I check in code of cli_programmer, and there is a condition on firmware size to be sure that firmware is smaller than 508kB.
Can you explain me why ?
Thanks,
Jérémy
