Other Parts Discussed in Thread: TIMAC

I am working on MAC coP of TIMAC. MAC coP to the module and can send commands via RS232 and receive feedback.

4. Setting up a TIMAC Network

4.1 Starting a PAN Coordinator

To Start a PAN coordinator following sequence of commands can be used to the MAC-coP from the Host
via the MT interface

Reset the MAC using the API : MAC_RESET_REQ
Set the parameters using the API: MAC_SET_REQ
1. Set the Short Address attributeID: ZMAC_SHORT_ADDRESS
2. Set the Extended Address attributeID: ZMAC_EXTENDED_ADDRESS
Scan the area for pre-existing PAN ID’s. send a MAC_SCAN_REQ
After receiving MAC_SCAN_CNF (AREQ) determine the existing PANID’s and select a unique PAN ID to start the network.
Start the MAC network using MAC_START_REQ
Set the parameters: MAC_SET_REQ
1. Allow Association: ZMAC_ASSOCIATION_PERMIT
2. Device On All the time : ZMAC_RX_ON_IDLE, set true for coordinator

Can you help me with the commands for setting up coordinator?

example:

SREQ                        ->              SRSP
0x fe 00 21 01 20 (Ping)                                          -> 0x fe 02 61 01 43 00 21
0x fe 01 22 01 01 23 (mac reset)                                    -> 0x fe 01 62 01 00 62

You can refer to section 4.1 Starting a PAN Coordinator in MAC COP Interface Guide.pdf

Hi Hung,

Section 4.1 covers starting a PAN coordinator, section 4.2 details starting network devices. Are you having any difficulties in executing these instructions?

Regards,
Ryan

Can you attach your sniffer log instead of screenshot?

Everything is in MAC COP Interface Guide.pdf. After you follow steps in section 4.1 Starting a PAN Coordinator, you also need to do steps in section 4.2 Starting Network Devices to make device join coordinator.

1. Reset the MAC State Machine using the API: MAC_RESET_REQ

2. After the reset. Set the following parameters using the API : MAC_SET_REQ

a. Set the Extended Address : ZMAC_EXTENDED_ADDRESS

b. Set RX On when idle = true

3. Scan the area in the radio range for existing PAN’s using the API MAC_SCAN_REQ. Various beacons will be received via the indication from the MAC – MAC_BEACON_NOTIFY_IND. Select an appropriate PAN to join after MAC_SCAN_CNF is received from the MAC which indicates that the network discovery has completed.

4. Then send the association request to the selected PAN Coordinator using the API: ZMAC_ASSOCIATE_REQ, but I don't see on sniffer, am I missing any steps ??

One issue I see with the document is that it uses "ZMAC_ASSOCIATE_[REQ/IND]" when it should be "MAC_ASSOCIATE_[REQ/IND]". Nevertheless the sniffer log shows a beacon response from the coordinator, are you not receiving a MAC_BEACON_NOTIFY_IND on the network device CoP? Refer to 5.3.20 to understand what the incoming packet structure will look like. You would then send a MAC_ASSOCIATE_REQ with the same CoordAddressMode, CoordAddress, and CoordPanId
