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

[Ziyao Zhou]

Hi

I am using nrf70-wifi-ble-image-transfer-demo in the nRF7002 DK.

I change nothing on the code form the sample, after patching I have succesfully build the code and then flash to the borad.

However, after flashing, there is nothing happending on the nRF7002 DK,even no printing printk("Starting %s with CPU frequency: %d MHz\n", CONFIG_BOARD, SystemCoreClock / MHZ(1));

I checked RTT there is nothing, and the serial terminal will only shows:

I try to debug but when I enter the dubug it can not stop by the main function.

Could you please help me on this, thank you so much!

Hi

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). ncs270_wifi_ble_camera_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

Thank you so much for your detailed information!

[Simonr]

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

Best regards,

Simon

Could you please kindly check this ticket about a new problem?

[Simonr]

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

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:

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);

}
