I'm having an issue with the I2C scanners both the multispeed and the regular one.
I am using the Nucleo L476RG (STM32L476RGT6U).
The results for both the I2C scanner and the multispeed end up comming with nothing.

Arduino I2C Scanner - 0.1.06
Scanmode:
s = single scan
c = continuous scan - 1 second delay
q = quit continuous scan
d = toggle latency delay between successful tests. 0 - 5 ms
Output:
p = toggle printAll - printFound.
h = toggle header - noHeader.
a = toggle address range, 0..127 - 8..120
Speeds:
0 = 50 - 800 Khz
1 = 100 KHz only
2 = 200 KHz only
4 = 400 KHz only
8 = 800 KHz only

However if I address the device (BME280 0x76) on its own with no scanner I can RW to it without issues.
Any Ideas?
