Ok, so the CPU and UART works :-)
And, the 32KHz clock domain works, hence the blinks.
Now, CPU can run from internal High Frequency RC or External crystal.
If your 32MHz crystal on the board has dry solder (or what ever has happened), then most probably internal RC remains to clock the SoC.
But 2.4GHz radio will not be 2.4GHz.
Zephyr v1.9 has Radio Direct Test Mode implementation, hci_uart sample can be used with DTM HCI commands to test the radio. The DTM HCI commands will fail to respond if the HF clock cannot source from a stable crystal.
And, yes nitrogen_beacon.hex from http://builds.96boards.org/releases/nVery unlikely (and likely based on conditions), I use nRF51 dongles over 5 years now, carry it around in bare hands, worst I have done is to have my 32KHz crystal go out of its spec. but BLE operational using the 32KHz RC.
I think Seeed need to contact our support (I am just a software guy).
