Bug Fixes

• calibration
  • (B91/B92/TL721X/TL321X) Modified the logic of judging frequency_offset_value in user_calib_freq_offset interface to ensure that it is consistent with the logic of RF frequency calibration value written to flash by the chip fixture frequency calibration value, in order to solve the problem that the chip fixture frequency calibration value does not take effect. This issue affects all SDKs and applications that require RF frequency calibration.

Bug Fixes

• calibration
  • (B91/B92/TL721X/TL321X) 修改了user_calib_freq_offset接口中判断frequency_offset_value的逻辑，使其保证和芯片夹具频偏校准值写入flash中的RF频偏校准值逻辑一致，以解决芯片夹具频偏校准值不生效的问题。此问题影响所有需要进行RF频偏校准的SDK和应用。
