How can I change the I2C address? #2476

I'm trying to use ssd1306 and a BMP280 sensor now but if I want to use them together, it doen't work. I tried to use the founction: u8g2.setI2CAddress(0x76); bmp.begin(0x77,0x58);

and I got this: rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2)) waiting for download

I wonder why it's 'waiting for download' Anyone can help me? Please.

Maybe you need to slow down u8g2 by using the setBusClock command.

See note 2 in the manual: https://github.com/olikraus/u8g2/wiki/u8g2reference#setbusclock
