Hello,

I want to connect QCA9377 with a LTE module.

But I didn't understand how to use the LTE coexistence pins with WLAN and BT.

Where and how do you connect the following 5 pins: LTE_UART_RXD, LTE_UART_TXD, WLAN_RFKILL_L, 3D_FRAME_SYNC and QOW?
Do you have an example of a reference design between the QCA9377 and an LTE module?
What is the scheme to implement to use this LTE coexistence?
 
Thank you very much for your help.
Best Regards

Hi Yann,

Have you checked the Device Spec. docs at https://developer.qualcomm.com/hardware/qca9377-x/tools ?
There are Pin-descriptions and there are Pin numbers for Coex as well.

We have the Reference Design and HW docs but they aren't available to be shared on open forums.
I'd suggest you to get help from the vendor from whom you bought QCA9377 modules.
Or else, to get access to Qualcomm internal documents and other proprietary resources, you may contact sales team at https://assets.qualcomm.com/contact-sales-iot.html  .

Thanks.
