BLE Encrypted Connection

Sat, 2020-04-11 10:54 -- Thomas Donhauser

Hello,

I have difficulties to determine if my peripheral BLE connection ist encrypted or not.  In my device configuration this value

service_config.sec_level = GAP_SEC_LEVEL_1

is set. I'm using GAP_SEC_LEVEL_1 to ease the connection and pairing.  This is done by the corresponding apps for iOS and Android. Also in the configuration 

#define dg_configBLE_SECURE_CONNECTIONS          (1)

is set. All I want to know is if the BLE-Communication is encrypted (LE Secure Connections) with my configuration or not.

SmartSnippets Studion Release Version ?

Fri, 2020-04-10 18:21 -- Dieter Falk

Hello, your acutal (10. Apr. 2020) Website shows the following Version for SmartSnippets: V1.6.3

I think is is an old version, because I already downloaded V2.0.20.1468 in October 2019.

I assume this was a mistake or was this downgrade done on purpose?

DA14680 restart itself after pm_set_sleep_mode(pm_mode_hibernation)

Tue, 2020-04-07 03:22 -- huiui

Hello,

 

I have found sometime DA14680 will restart itself after pm_set_sleep_mode(pm_mode_hibernation). The way I implement it is that there is a button on the board, and if button is clicked, it will run pm_set_sleep_mode(pm_mode_hibernation).

I am using a cunstom board. Strangly whether or not DA14680 will retart itself dpendens on situations, as summarized below.

 

DA14680 enter hibernation and not restart cases:

--Afer suota_initial_flash_jtag_win program . In this case, after  click button, it will stay in hibernate mode.

RetRAM0 overflow

Fri, 2020-04-03 18:06 -- Dieter Falk

Hello,

I am using the DA14683 device on the eval-board with the actual SDK and tools.

It seem that I have a problem with the memory layout, that the compiler tells me to run out of memory, when requiring more then 32 KByte RAM. The following will be show:
App.elf section `RETENTION_RAM0' will not fit in region `RetRAM0'
RetRAM0' overflowed by 32 bytes

The following is my actual configuration (from custom_config_qspi.h)
