stm32wb55: Zigbee - Touchlink Initiator as Sleepy End Device
Hello
I need to develop low power wireless device which is suitable of making target devices to join a network. After doing research I came to a conclusion Zigbee Touchlink(TL) Initiator Sleepy End Device(SED). But STM32CubeWB does not have any Touchlink examples so currently testing with existing coordinator and router examples with their .ioc configuration changed to Touchlink. I see no problem making connection between "RFD-TL-Initiator-ED" and "FFD-TL-Target-Router" but when ED is changed to SED the connection fails.
Only code difference between SED and ED is that SED does not set ZCL_TL_ZBINFO_RX_ON_IDLE flag on function APP_ZIGBEE_NwkForm().
So my question is
1. Is there another way to make SED-Initiator combination work? (maybe some example codes)
2. Is SED-Initiator combo not workable by Zigbee itself at the first place?
3. Maybe there's something else I am missing on?
Below is my current setup
- P-NUCLEO-WB55 with RFD stack x 1 (Initiator SED or ED)
- P-NUCLEO-WB55 with FFD stack x 1 (Target)
- Wireless Stack V1.18
- IDE - STM32CubeIDE
Target Project (TL router)
Imported Zigbee_OnOff_Server_Coord and Changed Zigbee Configuration as below
ED project (TL connections are OK)
Imported Zigbee_OnOff_Client_Router example and Changed Zigbee Configuration as below
SED Project (TL connection fails)
Imported Zigbee_OnOff_Client_Router example and Changed Zigbee Configuration as below (enabled CFG_FULL_LOW_POWER)
Results are Target - ED is OK, but Target - SED fails.
Code difference between ED and SED is the greeb line in below image does not exist in SED code generation.
Really appreciate your time for reading and any idea will be really helpful.
Thank you.
