MBH7BLZ02 not working

[mbozic]

Hi,

I have PCA10028 dev board and Fujitsu MBH7BLZ02 BT module.

I have successfully modified some sample code and when I flash it to nRF module on the PCA board, the code works. I can scan and connect to nRF and use it normally.

Now I'm trying to flash that code to MBH7BLZ02. I've connected MBH to PCA board over debug out connector. I can see the module as nRF51822 in nRFgo Studio, I can flash SoftDevice and application successfully, but MBH module is not seen on scanning. I use S110 for SoftDevice. I've tried S130 too but with same results.

I've also tried to set: SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_SYNTH_250_PPM, false); in static void ble_stack_init(void) ...with no luck.

My MBH module is connected directly via wires to PCA board since I need to do some testing first, but it seems I just can't get it to work(or advertise).

Am I missing something?

Thank you!

Best regards, Mladen

Hi. Do you know what nRF51 revision is on the MBH? I seem to recall it is a 16k variant and the PCA10028 is a 32k? Maybe it is a memory issue.

Have you tried other clock sources? Like the internal RC oscillator, NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION?

What Softdevice and SDK version number are you using?

Are you able to run simple blinky examples on the MBH?
