nrf5144 ANT+ two network can't work at same time

[Fema]

I am using the nrf51422 with softdevice 5144_2.0.1 , I set two network number using the "sd_ant_network_address_set" api , network number 0 for ANT+ cadence/heardrate.. network number 1 for shinamo di2 . I assign di2 channel to network number 1 then i can get the di2 broadcast message and if i assign cadence channel to network number 0 then i can get di2 and cadence message together .

But if i lost the cadence message (eg: uncheck the Bike cadence transmitting box in ANT+ sensor simulator tool) then i also lost the di2 message , if i close the cadence channel then di2 message back .

any comment . thanks

I post my code as below : If HRM channel not paired then i will not receive any ANT event from channel ANT_DI2RX_ANT_CHANNE.

It look like network 1 will NOT receive ANT event until all channels paired or close on network 0. Why ?? Thanks .

Sorry for not replying to you sooner. I'm not sure what is causing this. What SoftDevice and SDK version are you using? What hardware? What are the complete laser markings of the nRF51422 chip?
