WL1807MOD: Tx/Rx Switch Control Pin

Hi Sam,

Can you take a look at our WL8 Vendor Specific HCI commands? Does the HCI_VS_Get_System_Status (0xFE1F) solve your issue?

Best regards,

Jacob

Jacob,

Unfortunately, no. This would only provide a method to keep the chip in one mode or another. I want an indication of when the internal ADC is running vs when the internal DAC is running so I know when there is RF output on the ANT pins vs. when the chip is sampling RF input. Also, this switching likely occurs frequently, so an interrupt driven pin would be preferred over a status register that requires poling. Does anything like that exist for the chip?

Hi Sam,

I'll need to look into this further, I'll follow up by the end of this week.

Thanks,
Jacob

Sam,

Please help me understand, what is the need for doing this? Why do you need to separate the RX/TX paths? 

Sabeeh,

We require different filters and amplifiers on the transmit side vs the receive side in our application and would like to avoid using a circulator to split the paths.

Let me look into this and I will update you before the end of this week.
