Hi Dialog Team:
I am a newbie, how to download the SDK?

Peripheral Privacy Flag - Make Read Only
Hello Dialog,
I am trying to make the Peripheral Privacy Flag read-only. I found code similar to this on the forum and am executing it:
// Make Peripheral Privacy flag read only
// update the property of the attribute
ATTMDB_UPDATE_ATT_PERM(GAP_HDL_PRIVY_FLAG, WR, DISABLE);
Stack enforcement of LTK size
Does the DA14581 chip's BLE stack enforce the BLE LTK size limit (7-16 bytes) so that the application can always trust that the key size is valid?
Thanks!
UART read fails after a few attempts
我想创建一个任务响应ible for reading from serial using UART1.I find that after calling ad_uart_read a few times, eventually ad_uart_read() will block forever. I am using a USB to TTL adapter, which I can probe using a logic analyzer, so I know that the messages are going out on the wire, but ad_uart_read() still does not return.
By adding prints, I know that ad_uart_read() is blocking on this line:
OS_EVENT_WAIT(device->bus_data->event_read, timeout);
RSSI Readings Not Accurate
Hi,
We are retrieving the RSSI value from Dialog every 100ms while connected to a central and logging it in our application. We are getting some unexpected RSSI values when we setup the link to use more than 2 packets per connection event (our app can control the number of packets per connection event). We are using an MTU of 512 bytes (although the MTU size doesn't seem to matter) and we are performing write requests and indications over BLE of various sizes up to the MTU size- many of them are more than 20 bytes.
Pauses in DA14581 idle PDUs
Hello Dialog,
We are seeing some odd behavior with some of our systems containing DA14581 chips. In our system, the DA14581 is the slave device and different vendors are supplying the master BLE chips.
Smart Snippets Command-line read flash problem
Hi, Dialog Support Team:
I am using DA14581,external flash,MX25V1006F,1M-BIT [x 1/x 2] CMOS SERIAL NOR FLASH. and when I use Smart Snippets Command-line (Vesion 3.9) to download my hex file(30716 bytes), it shows that "Communication timed out: Requested 6144 bytes, received 0 bytes !". But it can dowload sucessfully when i use Smart Snippets with UI.
Minimum Power Off Time Before OTP Reloading
Hi Dialog,
Suppose a 14581 is running and then is cycle powered. What is the minimum duration of power down so that when power up the firmware will be reloaded from OTP rather than the previously loaded code already in RAM ?
Thanks

Hello Dialog,
In scatterfile_common_581.sct, we have the following:
Possible to hide (remove) Service Changed Characterisitc ?
Dear DLG support,
We'd love to remove the Service Changed Characterisitc so that phone client app should cache services across a device disconnect/connect cycle. Is it possible?
We are keen to do this to save battery in our application as we have static service on the server. We hope to achieve the goal so that clients can freely and permanently cache all handles found with no restrictions. The server guarantees they will not change during the lifetime of the device.
