Hi my name is Kevin, I'm designing bluetooth receiver. I try to design my own moudle using Dialog which I enclose with this post.
When I try my module, the SPI Flash is working but the installed IC DA 14580 doesn't work & it coudn't be detected by Smart Snippets
Note: while I check the voltage output on the IC, the voltage is exist and it's shown 3.3 volt
Hi,
May I'm to stupid but how can I Program with the Development Kit Pro a daughter board with smart snippets? Is there any Tutorial or something to read?
Best regards
Also OTP Programming
OTP is to use for Programming without any EEPROM External or or?
Dear Dialog_Support Team,
Hi，all！
今天,应用程序开发人员告诉我are times when connecting to Bluetooth there is this error: status = 133.
Do you know what's wrong with this?
Thanks！
hi，all
有2个问题：
大量数据长时间使用notify上传数据，有些时候notify这个操作会失败，导致丢包。
上传数据几分钟后出现蓝牙程序崩溃死机现象。
note：上传数据频率25hz，长度20字节，蓝牙连接间隔20-40ms
帮忙看下，thanks
HI!
I want to develop BLE master devecie using DA14580. is there any examples and documents to study ?
thanks！
你好,
We have developed and launched our product with DA14580. We are using DSPS profile for BLE communication.
Product link:https://www.kickstarter.com/projects/2078717030/phigolf?ref=nav_search
Our product works fine on Android (Android Kit Kat and above version).
But there is a problem on iOS (8 and above version).
The problem is unstable connection of BLE with iPhone. The BLE disconnects happen frequently without any message and notification.
你好，我是在SDK中的sleep_mode例程中进行修改，让设备一直广播，手机APP随时可以和它建立连接，建立连接后，当有按键按下后触发手机APP报警，再次按下取消报警，现在发现一个问题是，有时按键按着按着就不起作用了，手机蓝牙关掉在打开建立连接后又好了，会是什么原因导致按键后不能触发中断进行报警数据上传呢？
请问下是否环境干扰会对蓝牙通信距离产生音量。我们这里产线测试发现早上通信距离较好，但是到了中午距离就会较差。
如果会造成影响是否有解决方法？
我使用SDK版本为DA14580_581_583_SDK_3.0.10.1。
Hi,
Can I use Keil to burn external SPI Flash? How to config the project setting?
Best regards,
Daniel
