Posted on February 19, 2018 at 12:32Hello everyone,
I try to build a notification of the temperature characteristic of the SensorDemo example from de BlueNRG GUI. Unfortonatelly, that doesn't work. I follow the same scheme of the Notification for Acceleration Characteristic but that doesn't work.
Anyone know how I can access to the function SENSORDEMO_GET_TEMPERATURE() ?
Here's the code I have add to the SensorDemo_Central python script :
♯ Enable Notification for Temperature Characteristic
&sharpThe handle of descriptor is equal to temp_attr_handle+2
status= ACI_GATT_WRITE_CHAR_VALUE(Connection_Handle=conn_handle, Attr_Handle=temp_attr_handle+2, Attribute_Val_Length=2, Attribute_Val=0x0001)
if (status != 0x00):
ERROR( 'ENABLE NOTIFICATION FOR TEMPERATURE CHARACTERISTIC FAILED')
e = WAIT_EVENT(HCI_VENDOR_EVENT, timeout=30, Ecode=ACI_GATT_PROC_COMPLETE_EVENT)
&sharpReceive Notifications
while(True):
e = WAIT_EVENT(HCI_VENDOR_EVENT)
eCode = e.get_param('Ecode').val
if (eCode == ACI_GATT_NOTIFICATION_EVENT):
if e.get_param('Attribute_Handle').val == freeFall_attr_handle+1:
PRINT('---FREE FALL---')
elif e.get_param('Attribute_Handle').val == temp_attr_handle+1:
PRINT ('Ok')
PRINT ( 'READ TEMPERATURE CHARAC -> ' + str(SENSORDEMO_GET_TEMPERATURE(e.get_param('Attribute_Value').val)))
The last line of this code give me an error.
Thanks in advance,
Sylvain.
