Dear all

For XC7107 and XC109L(with cc2640r2f), we have IOT B2B application . XC109L need to start with 500K Broadcast and XC7107 is always scan. Our system always need to cover 200M long distance. Please check if CC2640r2f can do it? Do we need back to 1M for broadcast mode?

Hi
XC7107 is our gateway. it is always to scan tags. XC109L is tag,and it is always broadcast with BT 5.0 500K data rate. they both use TI CC2640R2F. solution.

According to my field test, I cannot have two CC2640R2F running BT 5.0 500K data rate to have 200M line-of-sight RF distance.

Dear YK
You mean CC2640r2f can set 500K to broadcast for long distance application. Although the distance of 500K cannot cover 200M, it is longer than 1M , right?

Yes, it's longer than 1M.
