The following sections document RS9116 WiSeConnect commands, parameters, responses and availability. For error codes returned by commands, see https://docs.silabs.com/rs9116-wiseconnect/latest/wifibt-wc-sapi-reference/error-codes .

Index #

This section explains various Bluetooth Classic commands, their structures, parameters and their responses. For API prototypes of these commands, please refer to the API Library Section.

A command should not be issued by the Host before receiving the response of a previously issued command from the module.

Parameters #

oper_mode

• Sets the mode of operation. oper_mode contains two parts <wifi_oper_mode, coex_mode>. Lower two bytes represent wifi_oper_mode and higher two bytes represent coex_modes .

  oper_mode = ((wifi_oper_mode) | (coex_mode << 16))

• Option 1
  • External 32KHz clock connection pins : XTAL_32KHZ_P & XTAL_32KHZ_N
  • Power Save connection pins : HOST_BYP_ULP_WAKEUP & UULP_VBAT_GPIO_3

rsibt_updategaintableoffsetMaxpower :: Update Gain Table Offset and MaxPower #

Description #

This command is used to configure region based gain table the module from user. This method is used for overwriting default region based gain tables that are present in firmware.

There are two types of gain tables for BT and BLE protocols

• Gain table holding Max Tx power values
• Gain table with Max power vs offset values Customer must configure both gain tables mentioned above in the same order to apply the changes in the firmware properly.

Note!

• This command must be used immediately after the opermode request.
• This command is applicable for High performance(HP) mode only.
• Internally, the firmware maintains two tables.
  • Gain table holding the Max Tx power values for all supported regions.
  • Gain table holding the Max power vs offset values for each channel for all supported regions
• There are 5 regions supported and they are FCC, ETSI, TELEC, KCC and WORLDWIDE. These FCC/ETSI/TELEC/KCC gain table max power level and offset values should be loaded in end-to-end mode via BT/BLE User Gain table. This has to be called upon on every boot-up since this information is not saved inside the flash. SoC uses these tables in FCC/ETSI/TELEC/KCC regions to limit power and not to violate the allowed limits.
• In worldwide regions, firmware uses worldwide TX power values. In other regions, firmware uses minimum of worldwide and region-based TX values. Keep in mind that these values vary with different parts. Also, the offsets are estimated during manufacturing, which are then applied as a correction factor during normal mode of operation.
• This frame has to be used by customers who have done FCC/ETSI/TELEC/KCC certification with their own antenna. All other customers should not use this. Any other use of this frame may result in violation of FCC/ETSI/TELEC/KCC or any other certifications and Silicon labs is not liable for it.
• In the max power per region configurations, update all regions.
• Update all the regions that are not certified with max power as ZERO.
• Update the world-wide region with proper max power provided in Gain Tables with the release. This represents values of the initial chip certifications.
• In max power vs offset configuration, only the region that is certified can be updated. Other regions can be ignored.
