I am designing a custom board with an i.MX8M Mini and I might use the module 1MW for wi-fi with the following requirements:
Based on these requirements, I was wondering if I can connect the 1MW through SDIO (CLK, CMD, DATA[0-3]) only. The requirement to turn off the power on the interfaces is to avoid interference with other radio interfaces our product needs that operate in frequencies close to the 2.4GHz and 5GHz.
Can we meet the requirements listed on the bullet points above using only the SDIO or do we need to use any other connection to do so (LPO_IN, UART) for configuration or anything else?
I think UART is ok in free mode if no BT function is used. but strongly suggest to add LPO even no sleep needed, we can do more tests with the boards with no LPO part, but can't gurantee in current design and software release before a lot of verifications .
