Bluetooth don't work on Fujitsu BLE module

[raron]

Hello,

I have a nRF51822 Evaluation Kit, and a working ble_app_uart demo software. I would like use the Fujitsu MBH7BLZ02-109004 module. I can flash and verify the softdevice and the app, i can blink a led so the microcontroller are running. I flashed the same app to the Fujitsu module and nRF51 EK, but the BLE don't work on the Fujitsu.

The LED blinking is slow. Maybe the oscillator, or the osc. config are bad? (The Fujitsu module have an internal crystal.)

Thank you.

Hi Try change in static void ble_stack_init(void)

SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_SYNTH_250_PPM, false);

Probably Fujitsu not use external 32KHz xtal
