Cannot bind app key for one of the model with PYACI Script

Question

Hello 
 I am trying to bind app key for one of the models with the help of PYACI Python script. I am using latest version v5.0.0 for PYACI script and downloaded it here: https://github.com/NordicSemiconductor/nRF5-SDK-for-Mesh , also with same version of documentation for commands https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v2.1.1%2Fmd_scripts_interactive_pyaci_README.html . And I am using Raspberry pi where my py script is running and nRF52840 with Serial Script running connected to Raspberry Pi with Ports /dev/ttyACM0 (or) /dev/ttyACM1. I am trying to bind app key for Sensor_Server Example and i get like this where all the earlier commands works well. 
 NOTE: examples are connected to Laptop which is obvious where we can run with bluetooth 
 
 I also tried with Mesh Chat sample like above and get same problem 
 
 Another Question: we can identify the sample with last model ID where vendor Setup Model ID bound to "0059000a" which is 8 bit and where it should be 4 bit. Even in app i get the same ID 
 which is ok to setup in app but in this command - cc.model_app_bind(db.nodes[0].unicast_address, 0, mt.ModelId(0x1000)) it should have only 4 bit right? 
 Please help me as soon as possible. I really in need of help to continue my work further 
 Regards

Hi Sai, 
 My sincerest apology for the very long wait. I had some very busy weeks, and it took a while to recover. 
 I returned to this case today and regretted not keep trying for just 15-20 minutes the last time I did. The issue was exceedingly simple. 
 In my previous script, I setup publication with a TTL of 1. That is not a valid value. I changed TTL to 2, and it works just fine. 
 I went over your earlier script and can see that it has the same value and the same error. Thus I believe changing TTL to a value between 2 and 127 should also fix it. 
 Here is an update script: 
 db = MeshDB("database/example_database.json")

p = Provisioner(device, db)
p.scan_start()
p.scan_stop()
p.provision("b9ed5250206146188612adafdf9e29e7", 0, "Sensor", 0, 0)
p.provision("f1f09dbd97e649818e0f62426819e67e", 0, "Observer", 0, 0)

cc = ConfigurationClient(db)
device.model_add(cc)

cc.publish_set(8, 0)
cc.composition_data_get()
cc.appkey_add(0)

cc.model_app_bind(db.nodes[0].unicast_address, 0, mt.ModelId(0x1100))
cc.model_publication_set(db.nodes[0].unicast_address, mt.ModelId(0x1100), mt.Publish(db.nodes[1].unicast_address, index=0, ttl=2, period=3000))
cc.model_publication_get(db.nodes[0].unicast_address, mt.ModelId(0x1100))

cc.model_app_bind(db.nodes[0].unicast_address, 0, mt.ModelId(0x1101))
cc.model_subscription_add(db.nodes[0].unicast_address, db.groups[0].address, mt.ModelId(0x1101))
cc.model_subscription_get(db.nodes[0].unicast_address, mt.ModelId(0x1101))

cc.publish_set(9, 1)
cc.composition_data_get()
cc.appkey_add(0)

cc.model_app_bind(db.nodes[1].unicast_address, 0, mt.ModelId(0x1102))

cc.model_subscription_add(db.nodes[1].unicast_address, db.groups[0].address, mt.ModelId(0x1102))
cc.model_subscription_get(db.nodes[1].unicast_address, mt.ModelId(0x1102))
cc.model_publication_set(db.nodes[1].unicast_address, mt.ModelId(0x1102), mt.Publish(db.nodes[1].unicast_address, index=0, ttl=2))
cc.model_publication_get(db.nodes[1].unicast_address, mt.ModelId(0x1102)) 
 Again, I am very sorry for the long wait.

 Hieu
