Thank you for feedback. I'll double check. By the way, did you insrease response timeout to 350msec..500msec for GD3200B? `mp3.begin(mp3Serial, 350, DFPLAYER_HW_247A, false); //false=no feedback from module after the command`

I'll give it a try, but the success rate is low since I don't have a GD3800D. Another problem is that the GD3800D datasheet is a copy-paste of the GD3200D...

I will add GD3800 soon (next 1..3 months).

Hi VojtechBartoska, I haven't tried "esp_wifi_set_max_tx_power()". But transmit power more than 15dBm doesn't work in 3.0.2.

Hi TD-er This is exactly what I use 802.11n. I'm not complaining, there's just no information about this in the help. Is it possible to add a small note to...

OK. Thank you.

In this case, do you need to correct the [example](https://github.com/espressif/arduino-esp32/blob/master/libraries/SPI/examples/SPI_Multiple_Buses/SPI_Multiple_Buses.ino) for the library?

I think [ind03](https://github.com/ind03) is talking about tLOW (LOW period of the SCL), minimum 4.7usec. See UM10204 Table.10 for datails. After if-else should be SU;DAT (data set-up time), minimun 250nsec.

According to IDF help I2S_MCLK_MULTIPLE_256 is the correct value > The field [i2s_std_clk_config_t::mclk_multiple](https://docs.espressif.com/projects/esp-idf/en/stable/esp32s2/api-reference/peripherals/i2s.html#_CPPv4N20i2s_std_clk_config_t13mclk_multipleE) indicates the multiple of MCLK to the sample rate. In most cases, I2S_MCLK_MULTIPLE_256 should be enough. However,...

What is your XTAL frequency? Are you using ESP32 at 160MHz or 250MHz?
