esp_wifi_set_max_tx_power(2). What am I doing wrong? https://github.com/espressif/esp-idf/blob/ef98a363e35dbc6bfd1caadfab8706874930f278/components/esp_wifi/include/esp_wifi.h#L897-L915 Param power unit is 0.25dBm, range is [8, 84] corresponding to 2dBm - 20dBm. 2 is invalid. Check your return values.

I've been using pinMode( 12, INPUT_PULLUP); , but this always return 0 (false) pinMode is void: https://github.com/espressif/arduino-esp32/blob/399f4ecbb3a4cef21e2bffa37adb6190356dfb76/cores/esp32/esp32-hal-gpio.h#L88 Do you mean that reading the pin level (ie. with digitalRead(12)) afterwards alwa...

I think that IRAM is not added to free heap on old esp32, which is a bug i believe, and maybe D/IRAM too (just educated guessing) There's a good post here that explains why: https://blog.espressif.com/esp32-programmers-memory-model-259444d89387 The IRAM can also be used for data, but with two impor...

Again, your Intellisense configuration is separate from your CMake configuration. You will never fix a compilation error by tweaking your Intellisense paths.

Make sure the component REQUIRES/PRIV_REQUIRES lwip in its CMakeLists.txt and then

You can't forward the va_list to sprintf. Try vsprintf.

20uA sleep current is easily achievable, excluding poor component selection or design error. No problems there. 5mA average active current is too low, considering most of that time will be actively transmitting/receiving over WiFi and doing work (TLS handshake, JSON construction). Wakeups per hour ...

See the "defines" item in this example config: https://code.visualstudio.com/docs/cpp/ ... e#_example

example_espnow_init: esp_now_peer_info_t *peer = new esp_now_peer_info_t[sizeof(esp_now_peer_info_t)]; send_param = new example_espnow_send_param_t[sizeof(example_espnow_send_param_t)]; I don't think your intention is to allocate arrays of these objects. send_param->buffer = new uint8_t(13); I try t...

You can use i2c_param_config again with the updated config

Code: Select all

  ESP_LOGI(TAG, "MAC : %d", esp_now_send(send_param->dest_mac, send_param->buffer, send_param->len));

Likely culprit here
