DA14580读取芯片ID号

Thu, 2018-11-01 01:36--lindapeng

你好,我想问一下,从哪可以读芯片的唯一ID号?我们在其他芯片中都有寄存器可以获取芯片的ID,但是在DA14580的芯片资料中没有发现这个寄存器,唯一发现的是CHIP_ID1_REG~CHIP_ID3_REG,但是看资料介绍这三个不是芯片的唯一ID。

DA14580连接后无服务

你好,我想请教一下,我们在测试中发现偶尔会有这种现象:广播时都正常,和APP连接后有MAC地址,但是无法发现服务,或者无法显示设备名称,重新连接后正常,可能是哪块地方的问题?怎么解决?谢谢

How to send senor data more than 20 bytes over the BLE

Tue, 2018-10-30 13:17--vishnuatdialog

Hello Dialog,
We have connected the sensor to Da14585 via I2C on our prototype board. Our sensor data length is 60 bytes, but BLE is broadcasting only 20 bytes that I have checked with the generic app(BLE scanner). I have tried to increase MTU size(.max_mtu), DEF_SVC4_LSM_ACC_X_CHAR_LEN = 60 but nothing is affected still broadcasting 20 bytes only.

NVM life expectancy when using I2C

Hello,
I'm designing what's essentially an I2C-to-PWM output driver, based on SLG46533.

For PWM, I'm using a DFF+Delay circuit described in September 2018 GreenPAK Cookbook, page 38: "Technique: Setting a Constant Duty Cycle". To control the PWM duty cycle, I use an idea from Application Note AN-1144 "I2C IO Controllers 8-bit BUS". I update CNT/DLY module's Counter Data via I2C by sending a command to modify the appropriate registers; for example, CNT2/DLY2 in SLG46533 is reg<1543:1536>. This solution works great in emulation, but...
