Problem solved after I delete

void app_bt_ready_callback(void)

{

LOG_INF("Bluetooth client ready");

// app_bt_send_client_status(((mega_info.camera_id == ARDUCAM_SENSOR_3MP_1 || mega_info.camera_id == ARDUCAM_SENSOR_3MP_2)) ? 1 : 2, current_resolution);

}

hello,

I have use the code in UDP and BLE, it's OK.

However, when I use the TCP with BLE, anytime I connect BLE, there will be error:

Done. Sorry about the late reply, but we had a long weekend with a bank holiday here in Norway.

I'm closing this ticket then, and we will continue in the new one.

Best regards,

Simon

Did you get the project up and running now or are there more action points from our end required?

We just tested on our end with the following .hex file and the DK set up like the images below. Can you try with the .hex file here (just built the project in NCS 2.7.0 as is). devzone.nordicsemi.com/.../ncs270_5F00_wifi_5F00_ble_5F00_camera_5F00_shell.hex

If you have issues with this .hex file as well, please upload images of your setup so we can double check how the setup looks on your end. Added ours for reference here:

Best regards,

Simon

I am using the same GPIO shows in overlay, which is P1.12-P1.15

RE: Cannot use nrf70-wifi-ble-image-transfer-demo in nRF7002 DK

Simonr — Mon, 26 May 2025 13:03:47 GMT

So, what GPIOs exactly are you using for SPI here? By default the SPI pins P0.08-P0.11 on the nRF7002 DK are connected to the external flash memory. In order to connect get these GPIOs to the appointed headers (P6 and P24) you need to short the following solder bridges on the back side of the nRF7002 DK: SB11, SB12, SB13 and SB14. This is explained in the nRF7002DK user guide.

Best regards,

Simon

Hi,

Today I have added the log to be

CONFIG_LOG=y
CONFIG_LOG_DEFAULT_LEVEL=3
CONFIG_USE_SEGGER_RTT=y
CONFIG_LOG_BACKEND_RTT=y
CONFIG_LOG_BACKEND_UART=y
CONFIG_LOG_PRINTK=y

Finally, I can see something from RTT, however, UART is still unavailable, it shows the same problems before.

I notice the SPI from nRF7002 DK's CS(12), CLK(15) and MOSI (13) shows the correct pattern, however, the code reporting

On the other hand, when I using the nRF5340 DK, the arducam can funtion correctly, the logic analyzer shows:

I think nRF7002 DK should have same SPI compared to nRF5340 DK, what is the problems here? Thank you so much!

I just added the overlay, I still cannot use the code

I thought I could use "west build -b nrf7002dk_nrf5340_cpuapp" to use the UDP mode, so I didn't include -DEXTRA_CONF_FILE=overlay_tcp_socket.conf

I think it's the problem from nRF7002DK, so I then use an nRF5340 DK the printing is:

After I flash again, the nRF5340 has the same printing problem before. I can not get the printing form nRF7002 DK and nRF5340 DK now.

Could youl please give me some advice？

RE: Cannot use nrf70-wifi-ble-image-transfer-demo in nRF7002 DK

Simonr — Fri, 23 May 2025 11:42:34 GMT

Did you follow the Firmware building and Wi-Fi Connection build steps from the Readme file here? Can you confirm you added the -- -DEXTRA_CONF_FILE=overlay_tcp_socket.conf

as an extra devicetree overlay here? It doesn't seem like that from your build config window.

Best regards,

Simon

Hi,

I just tried and the print out result is:

*** Booting nRF Connect SDK v2.7.0-5cb85570ca43 ***

Pins have been configured as secure.

My buide setup is

I have to optimize the size as it will exceed the Flash.

RE: Cannot use nrf70-wifi-ble-image-transfer-demo in nRF7002 DK

Simonr — Thu, 22 May 2025 13:28:59 GMT

Try choosing the board target: nrf7002dk/nrf5340/cpuapp_ns instead to use a non-secure target for this application. Then make sure to first do "Build", check that the build log compiles and completes without any big errors before pressing erase/flash. Then upload the log of the device flashing here so we can see if everything went as expected.

Best regards,

Simon

是的，我正在使用 SDK 2.7：

Do I have to do the OTP memory programming? I am a new beginner on this field, I just want this sample running and take a look.

Could you show me how to get Wi-Fi® Radio test?

RE: Cannot use nrf70-wifi-ble-image-transfer-demo in nRF7002 DK

Simonr — Wed, 21 May 2025 13:43:32 GMT

Can you confirm you're using the supported SDK version (nRF Connect SDK v2.7.0)? How did you build and flash the board exactly. Additionally, if the nRF7002 is brand new (not used previously) you might need to do OTP memory programming. See the application note for reference: https://docs.nordicsemi.com/bundle/nan_043/page/APP/nan_043/otp_programming.html

Additionally, did you follow all the steps in the Wi-Fi BLE image transfer demo readme file when building and flashing this device?

Best regards,

Simon
