nvds里面的NVDS_TAG_BLE_CA_MIN_RSSI值调整
我想调整一下nvds里面的NVDS_TAG_BLE_CA_MIN_RSSI // Default Minimal RSSI Threshold - -48dBm
sdk里面的值配置的是0x40，
这个值得配置大小对信号有什么影响，值的范围是多少？
谢谢！
Boot problem in unstable voltage environment
Hi
We have some problem with boot sequence in unstable voltage environment.
1) Our FW is uploaded from Flash via SPI and we don't use OTP at all.
As part of system test we generate brief voltage drop during FW upload from Flash to RAM.
This voltage drop is not so deep to reset MCU, but deep enough to disrupt FW upload.
According to Figure. 1 from "AN-B-001 - DA1458x Booting from serial
Voltage drops due to battery contact
hi,
we have a issue with voltage drops due to battery contact (drop voltage can be longer than a 100mSec) , we decided to add a supervisor IC that connected to RST pin.
As long as a supply voltage is at least 2.3v then RST pin is at High Z mode, once the voltage dropped under 2.3v than the supervisor pulls up a RST pin to high.
can you suggest us about some supervisor (voltage monitor)?
thanks

Hi Dialog
SPI Flash programming through UART
Hello,
Is it possible to program external SPI flash through UART with the SmartSnippets?
SPI interface uses these pins, P0_0, P0_3, P0_5 and P0_6. And some of UART1/2/3 interface
pins use the same pins as SPI. For example, Rx2 pin of UART2 is the same as MISO of SPI.
Does that take any conflict?
Thanks for your help,

Different between 14580 and 14680
Dear dialog stuff,
When I begin to design a wearable device with 14580, a new chip 14680 come to me, and it seems also good for wearable device, so, could you briefly tell me the differences between them?
Thanks
Custom SPI Flash Application and jtag_programmer
We have a need to write an spi flash programmer similar to the SPI Flash Programming of SmartSnippets.
Reason being that we want a Flash Programming UI that can automate a few things without requiring the user to have to know the offset address of each area of flash should store what data besides the DA Application FW. With SS, the user has to know the offset address location to flash a certain piece of data for FW consumption.
With that,
GPIO usage definition
I would like to understand this block of code coming from system_ARMCM0.h
#ifdef __USE_GPIO
ARM_GPIO0->DATA[0].WORD = 0;
ARM_GPIO0->IE = 0;
ARM_GPIO0->DIR = 0xff83;
ARM_GPIO1->DATA[0].WORD = 0;
ARM_GPIO1->IE = 0;
ARM_GPIO1->DIR = 0;
ARM_GPIO2->DATA[0].WORD = 0;
ARM_GPIO2->IE = 0;
ARM_GPIO2->DIR = 0;
#endif
}
What are the DIR and IE commands and where are they located?

Changing advertise parameters in 'gap_cfg_table' at runtime?
I'm using PAN1740, with SDK 5.0.3 and DSPS.
I have to change the some gap configuration values values - at runtime!
MT_Dialog提到使用'custom advertising function', but did not give details for that here:

About verification when writing firmware in EEPROM with Smart Snipets
Hi, Dialog
While the EEPROM is not operating properly, a message appears indicating that verification succeeded.
Why did you decide that smart snipets succeeded in verifying?
Please tell me how to confirm that writing was successful.
Regards,
Sean
