sd_ble_gatts_value_set in S130

[Anne van Rossum]

The new version of the S130, alpha 0.9 has a different signature for the sd_ble_gatts_value_set function.

sd_ble_gatts_value_set(_handles.value_handle, 0, &value.length, value.data);

becomes:

ble_gatts_value_t p_value;                                                                                           
p_value.len = value.length;                                                                                          
p_value.offset = 0;                                                                                                  
p_value.p_value= value.data;                                                                                         
sd_ble_gatts_value_set(_handles.value_handle, 0, &p_value); 

However, this leads to a 0007 error:

[cs_main_crownstone.cpp : 399 ] Running while ticking..
[cs_BluetoothLE.cpp : 204 ] ERR_CODE: 7 (0x7)

Or as a stack-trace:

In other words: NRF_ERROR_INVALID_PARAM.

Am I doing something weird here?

Oops... getting late in the day...

Following solves it:

sd_ble_gatts_value_set(_service->getStack()->getConnectionHandle(),                                                                
        _handles.value_handle, &p_value); 

I just skipped over the fact that you now need two handles as arguments in this setter.
