I am developing AoA for nRF52833.
Please tell me about antenna switching.
Setting:
PSEL.DFEGPIO[0]=28
PSEL.DFEGPIO[1]=29
PSEL.DFEGPIO[2]=30
PSEL.DFEGPIO[3]=31
SWITCHPATTERN=0x0
SWITCHPATTERN=0x0
SWITCHPATTERN=0x1
SWITCHPATTERN=0x2
SWITCHPATTERN=0x4
SWITCHPATTERN=0x8
GPIO.DIRSET=0xF0000000
GPIO.OUT=0x00000000
Use CTE inline mode.
If Advertising with CTEInfo is received, the antenna switch will work as expected.
If Advertising without CTEInfo is received, PORT28/29 will change immediately after receiving the Advertising. (It outputs a pulse)
(There will be no change if no Advertising is received at all)
Is this normal operation?
