sl_status_t sl_zigbee_force_tx_after_failed_cca (uint8_t csmaAttempts)
Disable CCA after a number of consecutive CSMA failures due to CCA.
| N/A | csmaAttempts | The number of consecutive CSMA failures due to CCA prior to disabling CCA. The maximum allowed value is 3. A value of 0 disables the feature. |
For each packet to be transmitted by the MAC, disables CCA after a number of consecutive CSMA failures due to CCA. The packet is then transmitted using the standard number of mac retries, but with CCA off. Note that each CSMA failure consists of 5 failed and backed off CCA checks, which can take up to 35 milliseconds. The maximum allowed value for csmaAttempts is 3. A value of 0 disables the feature.
Returns
sl_status_t SL_STATUS_INVALID_PARAMETER, if csmaAttempts is out of range, SL_STATUS_OK otherwise.
