ROM 代码日志默认打印至 UART0 和 USB 串口/JTAG 控制器。当 EFUSE_UART_PRINT_CONTROL 和 EFUSE_USB_PRINT_CHANNEL 都为 0 且 USB 串口/JTAG 控制器已开启的情况下，ROM 代码日志可打印至 UART0 与 USB。

它们的控制是相互独立的。

Hi everyone,

Yes, you can choose an external antenna with a maximum gain smaller than 4.0 dBi.

We only measure the gain of PCB antennas and do not measure that of external antennas. Generally, we recommend the maximum gain of external antennas should be smaller than 2.33 dBi.

Hi, we have tested the current consumption of ESP32-S3 with flashing the example system/ulp/ulp_riscv/gpio. The measurement is also about 400 uA.

However, the current consumption is higher than expected. We will check the example later.

Hi, if you issue a read multiple request, you will receive only one ESP_GATTC_READ_MULTIPLE_EVT for all characteristics. The callback param contains the value of each characteristic (set of values, no longer than ATT_MTU-1) but doesn't contain the handle of each characteristic.

Hi, the params of the event ESP_GATTC_READ_MULTIPLE_EVT is struct gattc_read_char_evt_param (same as ESP_GATTC_READ_CHAR_EVT ). Related header file will be updated soon.
In addition, you can deal with this event by adding it to the function gattc_profile_event_handler . See the example https ...

Thank you for bringing this to our attention. The link has been fixed.

The first field (#1) indicates the total number of packets received in this period. In this case, the field value is e19.

The second field (#2) indicates the number of packets received at the corresponding rate in this period. In this case, the field value is 0.
