STM32WB5MMG short-range joining network

[ZChen.6]

Zigbee test using 1xZC and 1xZR.

For ZR to join network, the distance to ZC was limit to arround 2m.

After join network, the distance ZR message to ZC can be extended to about 20m.

Not understand why the join distance so short.

Here's my test setup:

• Hardware platform STM32WB5MMG development Kit (MB1292C)
• Stack/Version: stm32wb5x_Zigbee_FFD_fw / v1.14.1
• Application: Zigbee_OnOff_Server_Coord & Router

Thanks.

Update..

From FAE: Using the following code to let ZC ignore LQI constrain before forming network:

==

uint32_t val32;

val32 = ZB_BDB_FLAG_IGNORE_COST_DURING_JOIN;

status = ZbBdbSet(zigbee_app_info.zb, ZB_BDB_Flags, &val32, sizeof(val32));

==

The distance had extend from 3m to about 10(~12)m.
