question: How can i use two MAX30102 i2c sensors with an esp8266 that have the same address?
I haven't seen anyone use that particular library with the ESP8266 yet. I've personally tried the core Wire library, the Enjoyneering library, and the brzo_i2c library. The only issue I see offhand with that Multi_Bitbang library is at line 185 in the source: it's only waiting a half bit-time for the ACK, which will fail (NACK) with any part that does clock stretching; it won't see the ACK. The I2C spec allows for slave clock stretching on any of the bits, although I've only seen stretches on the ACK bit myself with the parts I've used.
