Re: Regulatory - Approved antennas list for ESP32-WROOM-32UE

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.

Re: ESP32-S3 ULP current consumption

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.

Re: No callback parameter documented for ESP_GATTC_READ_MULTIPLE_EVT

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.

Re: No callback parameter documented for ESP_GATTC_READ_MULTIPLE_EVT

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://githu...
