Re: ESP32 wifi couldn't connect to specific SSID

WiFive,
For my developing set up, I only have one AP, one esp32, one app to send the SSID and passkey, over and over again to test the system reliable.
Could you please suggest where/what I can insert the debug trace to get more information to provide to you?

Re: How to rewrite EFUSE

WiFive, I came across these code which indicate we can rewrite new value for efuse. Is that correct? void esp_efuse_burn_new_values(void) { REG_WRITE(EFUSE_CONF_REG, EFUSE_CONF_WRITE); REG_WRITE(EFUSE_CMD_REG, EFUSE_CMD_PGM); while (REG_READ(EFUSE_CMD_REG) != 0) { } REG_WRITE(EFUSE_CONF_REG, EFUSE_C...

Re: I2S DMA status

Since noone has any suggestion, I am continuing to dig in the source code. My goal is trying to find a way that either query status register method, or call back function is the refer method, to find out when each of the buffer is successfully DMA out, and when the entire data is DMA out. Below is m...

Re: How to rewrite EFUSE

WiFive, Thank you for your confirmation of efuse can't be erase. The reason I can't use the main nvs because the nvs space has the sticky data that will be read/write quite often, which can be full erase once it is full and erase will also erase my serial number. I need a small space about 10 bytes ...

Re: How to rewrite EFUSE

WiFive, Thank you for the link. I used the information in that link to execute esp_efuse_write_field_blob()- writes an array and read back the information using esp_efuse_read_field_blob()- returns an array of read eFuse bits. However, when I tried to write different value again, I got ESP_ERR_EFUSE...

I2S DMA status

Hi guys, Is there any register or any api function call or any call back function I can use to query for the status of the data transfer out from I2S DMA? I am currently using I2S DMA for the built-in DAC, I have the problem of cutting short the sound playing by stop too early. The problem will go a...
