A question about MTU

Tue, 2017-11-28 05:07--stanley_yeh

Hi Dialog,
我have a question about MTU.
我want to send a file from mobile to DA14585.
我f I set max_mtu of DA14585 to 255, and every time the app sends 240 bytes to DA14585 until the file has been transmitted.
The connection interval is 40ms, I am not sure how many packets (maybe 6?) per connection interval.
Each packet contains 20 bytes, right?
6 packets * 20 bytes = 120 bytes, so 240 bytes should be sent about 80 ms, is that true?
我use a debug pin to estimate, we find that DA14585 receives 240 bytes data just about every 40 ms, why?

Boot from SPI Flash

Mon, 2017-11-27 13:46--wisilica

Hi,

我am using custom board with DA 14585 chip. I have configured P0_0 as CLK, P0_1 as CS, P0_2 as MISO and P0_3 as MOSI. The firmware is copied into flash using smart snippets toolbox. The requirement is to boot the device from flash. But, this is not happening. Is it because the of the pins configured ?
我s it mandatory to use P0_0 as CLK, P0_3 as CS, P0_6 as MOSI, and P0_5 as MISO, for the device to boot from flash ?

Thanks

SUOTA tutorial error

Fri, 2017-11-24 22:13--TMiranda

Hi guys.

我'm using the DA14585 Basic Dev-Kit with the 6.0.6 SDK, trying to run the SUOTA Tutorial (number 6). I've faced a few problems that I would like to question.

1. There's no DA1458x_SUOTA_Multipart_Binary_Generator_0.rar on the DA14585 Software & Tools page. I've had to download it from the DA14583. Is there a reason for this?

2. The SUOTA tutorial ask you to use a ble_585_sw_version.h file to generate the .img files. This file doesn't exist on the SDK 6.0.6 (or I have been unable to find it).

Memory Location for Images of Dual Image Bootloader

Fri, 2017-11-24 11:09--jlabuac

Hi Dialog,

我have 2 images with sizes of 27kB. Then for the dual image bootloader configuration I set the following memory location:

MEM_LOC_FOR_FW_1_IMG = "0x8000"
MEM_LOC_FOR_FW_2_IMG = "0x1F000"
MEM_LOC_FOR_PRODUCT_HEADER = "0x38000"

我t could not boot. But when I changed it to the following:

MEM_LOC_FOR_FW_1_IMG = "0x4000"
MEM_LOC_FOR_FW_2_IMG = "0x1F000"
MEM_LOC_FOR_PRODUCT_HEADER = "0x38000"

我t booted successfully.

Flash issue - DA 14585

Fri, 2017-11-24 05:38--wisilica

Hi,

We are using custom manufactured board with DA 14585 chipset. The external flash being used is winbond flash memory w25x20cl. While trying to access the flash using smart snippets toolbox(v 4.8.3.1804 ), the chip is getting successfully connected, but the read, write or erase operations are not working. Kindly suggest the reasons for the same.

Thanks

Soldering recommendations for WLCSP34 package

Wed, 2017-11-22 21:25--erichn

我s there a recommended wave soldering temperature profile for the WLCSP34 package for DA14585? I did not see this in the datasheet. In particular, I would like to know if there is a maximum temperature it can tolerate during soldering in an oven, and what the recommended temperature during the reflow stage is.

Thanks
