Other Parts Discussed in Thread: CC1125

hi ,

i'am implementing tranceiver modules using CC1125 radio chip.

when the radio is idle bytes from uart has moved to a local buffer then when the previous transmission has completed then starts immediately.

this causes the radio packet sent ack  was not giving to micro controller hence it get locked in no  packet status received.

if i put interval 100ms after the tx success status it works.

how can i check the whether the RF was ready for transmission.

regards.

Rajesh

    Hi Rajesh,

    You can read the MARC_STATE field of the MARCSTATE register of cc1125 to find out the current state of the radio. Also, you can configure two of the GPIOx_CFG pins to output MARC_2PIN_STATUS signal to find out if the radio is in TX or SETTLING. Please see sections 3.4.1.1 and the register description of MARCSTATE register in section 11 of the User's Guide for more details.

    User's Guide.

    Best Regards,

    Vihang
