nRF 7002DK - BLE sample codes on SDK V.2.4.1

[GozdeGuvendi]

Hİ,

I can build and flash the basic samples like blinky, buttons etc. on the latest SDK v.2.4.1, but when i try to flash the bluetooth examples on the directory  (...\v2.4.1\zephyr\samples\bluetooth) , create the build configurations for board ( nrf7002dk_nrf5340_cpuapp_ns) and flash the device, i took some error like ;

[error] [ Client] - Encountered error -90: Command read_memory_descriptors executed for 15 milliseconds with result -90
[error] [ Worker] - Can't read memory descriptors, ap-protection is enabled.
[error] [ Client] - Encountered error -90: Command erase_file executed for 61 milliseconds with result -90

How can i solve this problem and try the BLE samples on the latest SDK version? Are these files compatible for nrf7002dk_nrf5340 ?

I tried nrfjprog --recover but this action could not solve my problem.

Thanks for your help.

Please try to run "west flash --recover".

Hi Amanda,

I couldn't try it, i took this message:

west : The term 'west' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and
try again.
At line:1 char:1

I also tried : nrfjprog --recover ,  but the first flashing error ramains the same. 

Thank you.

Hi,

but when i try to flash the bluetooth examples on the directory  (...\v2.4.1\zephyr\samples\bluetooth) , create the build configurations for board ( nrf7002dk_nrf5340_cpuapp_ns) and flash the device

Which sample are you using?

Hi,

I solved this problem by using these commands:

nrfjprog --recover --coprocessor CP_NETWORK
nrfjprog --recover --coprocessor CP_APPLICATION

Now, i want to ask that when i try the bluetooth beacon or broadcaster examples, i can send the advertising data to terminal of VS code, but i cannot connect to the desktop tool for bluetooth low energy. Should i use the external dongle for BLE connection like nRF 52840 ?  ( I use nrf7002dk , nrf5340 )

I will insert the screenshot, when i try to connect on tool.

Hi, 

nRF Connect Bluetooth Low Energy allows you to set up a local device, connect it to advertising devices, and discover their services, so you would need another device like nRF52DK/nRF52840DK/nRF52840 Dongle.
