Waleed's have more information shared in this thread.
There is another thread which asks you to check if both builds are built with the correct version.

I think it is the bt_enable(null) that is failing. I do not get the pass or failed message. it does not return. This is the exact call used in preipheral_uart and it enables the BLE just fine and returns the passed message.

err = bt_enable(NULL);

if (err) {

printk("Bluetooth enable failed (err %d)\r\n", err);

return 0;

}

printk("Bluetooth enabled\r\n");

Hi Timothy,

In recent day I've faced similar type of problem in which I was connecting xiao ble nrf52840 with nrf9151dk, and facing same timeout problem. It turned out it was the voltages issue, nrf9151dk operates on 1.8V normally(can be configured) and xiao board was operating on 3.3V due to which it can't receive data. When I replaced nrf9151dk with nrf52dk it worked. Maybe it worked in your case or maybe not but I thought it would be better to respond as it look similar to my case.
