Hello,
In a nut shell i am try to get a Model in PyACI to subscribe to a group address and display events. i have had limited success. and will try to explain as best i can. thankyou for your help.
i have successfully completed all steps in the Interactive mesh provisioning and configuration
we are using two PCA10040 / nrf52832 DK's. loaded with:
examples/serial/serial_nrf52832_xxAA_s132_6.0.0_merged.hex
examples/light_switch/client/light_switch_client_nrf52832_xxAA_s132_6.0.0_merged.hex
i have created a custom Generic On Off Server model in models/generic_on_off_server.py
from mesh.access import Model, Opcode
from models.common import TransitionTime
import struct
class GenericOnOffServer(Model):
GENERIC_ON_OFF_SET = Opcode(0x8202, None, "Generic OnOff Set")
GENERIC_ON_OFF_SET_UNACKNOWLEDGED = Opcode(0x8203, None, "Generic OnOff Set Unacknowledged")
GENERIC_ON_OFF_GET = Opcode(0x8201, None, "Generic OnOff Get")
GENERIC_ON_OFF_STATUS = Opcode(0x8204, None, "Generic OnOff Status")
MESH_MESSAGE_RECEIVED_SUBSCRIPTION = Opcode(0xD1)
def __init__(self):
self.opcodes = [
(self.GENERIC_ON_OFF_GET, self.__event_handler),
(self.GENERIC_ON_OFF_SET, self.__event_handler),
(self.GENERIC_ON_OFF_SET_UNACKNOWLEDGED, self.__event_handler),
(self.MESH_MESSAGE_RECEIVED_SUBSCRIPTION, self.__event_handler)]
self.__tid = 0
super(GenericOnOffServer, self).__init__(self.opcodes)
@property
def _tid(self):
tid = self.__tid
self.__tid += 1
if self.__tid >= 255:
self.__tid = 0
return tid
def __event_handler(self, opcode, message):
print("Server Event {} {}".format(opcode, message))
self.logger.info("Server EVent {} {}".format(opcode, message))
i can think configure this using interactive_pyaci.py with the following commands.
In [1]: db = MeshDB("database/example_database.json")
In [2]: p = Provisioner(device, db)
# SubnetAdd: {'subnet_handle': 0}
# AppkeyAdd: {'appkey_handle': 0}
# AppkeyAdd: {'appkey_handle': 1}
In [3]: p.scan_start()
# Received UUID 0059ccaa0000000076e52d5e787484ee with RSSI: -23 dB
In [4]: p.scan_stop()
In [5]: p.provision(name="switch")
# DevkeyAdd: {'devkey_handle': 8}
# AddrPublicationAdd: {'address_handle': 0}
In [6]: cc = ConfigurationClient(db)
In [7]: device.model_add(cc)
In [8]: cc.publish_set(8, 0)
In [9]: cc.composition_data_get()
#{ .... }
In [10]: cc.appkey_add(0)
In [11]: cc.model_app_bind(db.nodes[0].unicast_address+1, 0, mt.ModelId(0x1001))
# config database should now looks as follows

In [13]: device = d[0]
In [13]: device.event_filter_disable()
In [14]: device.send(cmd.AddrSubscriptionAdd(db.groups[0].address))
# AddrSubscriptionAdd: {'address_handle': 1}
# it should now be possible to see the events appear in the console when the buttons 1 and 2 are press on the light switch DK
# if they do not appear try changing logging levels to debug
# press
# DEBUG - ttyACM0: parsed_packet {event: MeshMessageReceivedSubscription, data: {'src': 17, 'dst': 1, 'appkey_handle': 0, 'subnet_handle': 0, 'ttl': 1, 'adv_addr_type': 1, 'adv_addr': bytearray(b'\xf4\xc0\x02\x12*\xdf'), 'rssi': -18, 'actual_length': 6, 'data': bytearray(b'\x82\x02\x01\x00\x01\n')}}
# however these event are not connected to the GenericOnOffServer Model because it has not been created yet
In [15]: gs = GenericOnOffServer()
In [16]: device.model_add(gs)
In [18]: gs.publish_set(8, 0) # not sure this is nessisary as this model never publishes events
this is where my confusion starts.
the GenericOnOffServer model was not required to get the events to appears in the log.
it was the AddrSubscriptionAdd serial command which caused the events to appear.
device.send(cmd.AddrSubscriptionAdd(db.groups[0].address))
and the events never make it to the GenericOnOffServer model.
now this somewhat makes sense because the model would have to have the group address in its subscriptions. which has never been set.
i considered / tried using Access Layer Model Subs Add serial command but this didnt not work because i did not know the Handle for the model.
this made me realize the models implemented in PyACI / serial API must work very differently to models embedded on a device.
they have no model ID, no subscriptions, and can not have any configuration commands run against them from a mesh configuration client.
so questions:
- is my configuration correct? have I missed any steps that would allow these events to be passed though to the Model? or is this the expected behavior?
if the is the expected behavior then:
