The following section introduces how to modify the 112 ~ 114 byte parameters. Figure 6-3 shows the initial conguration. 6. Downloading the Firmware Figure 6-3. 112 114 Byte Parameters Modify the RF Initialization Parameters Byte 114 is used to control THE RF initialization when ESP8266 is powered on. Table 6-5 provides the parameter conguration. Note:
Supported by ESP8266_NONOS_SDK_V1.5.3 and ESP8266_RTOS_SDK_V1.3.0 and higher. Option byte 114 = 0 byte 114 = 1 Table 6-5. Modify RF Initialization Parameters Description Only a VDD33 calibration is performed during the RF initialization. It takes about 2 ms and the least initial current. The default value is 1. VDD33 and TX power calibrations are performed during the RF initialization. It takes about 18 ms and small initial current. byte 114 = 2 The same as when byte 114 = 0. byte 114 = 3 All calibrations are performed during the RF initialization. It takes about 200 ms and large initial current. Correct Frequency Offset Byte 112 and byte 113 relate to the frequency offset correction. Table 6-6 provides the parameter conguration. Note:
Supported by ESP8266_NONOS_SDK_V1.4.0 and ESP8266_RTOS_SDK_V1.3.0 and higher. Table 6-6. Options for Frequency Offset Correction Option bit 0 Description The default value of byte 112 is 0. This bit is of the highest priority. bit 0 = 0: frequency offset cannot be corrected. bit 0 = 1: frequency offset can be corrected. Espressif

Description The default value of byte 112 is 0. When value = 0, it means that the bbpll is 168 M. Both positive and negative frequency offsets can be corrected. However, this may effect the digital peripheral performance and, therefore, it is not recommended. When value = 1, it means that the bbpll is 160 M. Only the positive frequency offset can be corrected. When value = 0, it means that the chip will track and correct the frequency offset automatically. The initial correction value is 0. When value = 1, it means that the chip is manually programmed to change the frequency offset to that of byte 113, so the chip will not track and correct the frequency offset automatically. When value = 2, it means that the chip will track and correct the frequency offset automatically. The initial correction value is that of byte 113. The default value of byte 113 is 0. 113 byte It is the value when the frequency offset is corrected manually or the initial correction value in frequency tracking. The data type is sign int8, in multiples of 8 kHz. 6.3.3. Conguration Examples The conguration of bytes 112 and 113 depends depends on users' specic needs. We provide some examples below:
1. The module works at ambient temperature, and needs no correction of the frequency offset. Set byte 112 = 0, byte 113 = 0. 2. The module works at ambient temperature and needs no automatic tracking and correction of the frequency offset; yet the frequency offset is large. In this case, a manual correction of the frequency offset is recommended. If the frequency offset is +160 KHz (at ambient temperature), users can set byte 112
= 0x07, byte 113 = (256 - 160/8) = 236 = 0xEC. If the frequency offset is -160 KHz (at ambient temperature), users can set byte 112 =
0x05, byte 113 = 160/8 = 20 = 0x14. This may effect the digital peripheral performance, so we do not recommend it. 3. Applications, such as smart lights, work at a wide temperature range of -40 C to 125 C, and need to track and correct the frequency offset automatically. The frequency offset at ambient temperature is small, so the initial offset correction value is not needed. Set byte 112 = 0x03, byte 113 = 0. Espressif

6. Downloading the Firmware 4. Applications, such as smart lights, work at a wide temperature range of -40 C to 125 C, and need to track and correct the frequency offset automatically. The frequency offset at ambient temperature is large, so the initial offset correction value is needed. If the frequency offset is +160 kHz (at ambient temperature), users can set byte 112
= 0x0B, byte 113 = (256 - 160/8) = 236 = 0xEC. If the frequency offset is -160 kHz (at ambient temperature), users can set byte 112
= 0x09, byte 113 = 160/8 = 20 = 0x14. But this may effect the digital peripheral performance and needs substantive tests, so we do not recommend it. We recommend Example 3. When the conguration of RF initialization is done, click GenInitBin button to generate esp_init_data_setting.bin. In addition, users can click Default button to set the value of frequency offset to default, or click LoadInitBin button to import a binary le for conguration. Espressif

Radiated Emissions in the Restricted Band Ambient condition Temperature 23C ~25C Relative humidity 45%~50%
Pressure 101.5kPa Method of Measurement The test set-up was made in accordance to the general provisions of ANSI C63.10-2013 section 6.3.1 Tabletop devices shall be placed on a nonconducting platform with nominal top surface dimensions 1 m by1.5 m. For emissions testing at or below 1 GHz, the table height shall be 80 cm above the reference ground plane.For emission measurements above 1 GHz, the table height shall be 1.5 m. The test was performed at the distance of 3 m between the EUT and the receiving antenna. The turntable shall be rotated from 0 to 360 degrees for detecting the maximum of radiated spurious signal level. The measurements shall be repeated with orthogonal polarization of the test antenna. RBW is set to 100kHz.The data of cable loss and antenna factor has been calibrated in full testing frequency range before the testing. Sweep the whole frequency band through the range from 9kHz to the 10th harmonic of the carrier, and the emissions less than 20 dB below the permissible value are reported. Set the spectrum analyzer in the following:
(a) PEAK: RBW=1MHz /VBW=3MHz / Sweep=AUTO
(b) AVERAGE: RBW=1MHz /VBW=3MHz / Sweep=AUTO This setting method can refer to KDB 558074. The field strength of spurious emission was measured in the following position: EUT stand-up position (Z axis), lie-down position (X, Y axis). The worst emission was found in lie-down position (Y axis) and the antenna is vertical. The test is in transmitting mode. Test setup TA Technology (Shanghai) Co., Ltd.
