IN100 nanobeacon issue with SHT40

Hello Team,

I am using custom adverising mode at BLE 1MPHY to configure sparkfun IN100 nanobeacon with latest nanobeacon tool (Ver 3.3.4) although this updated version does not have the capacity to activate LE 125 kbps speed transmission for long ranges.

My question is whether I can use BME280 (SEN 15440 Breakout board) also for interfacing with IN100 nanonbeacon? I have the sensor breakout board with me but I could not find the correct configuration file from the github repository? Can you please provide the correct configuration file to be burned on the nanobeacon while interfacing with BME280 temperature humidity sensor? Also I believe with i2c sensor only one timing burn is a limitation.

Is the above configuration file the correct one? If not can you provide a working configuration file?

Also if I want to interface SHT40 with IN100 nanobeacon using qwickk connector, should I use the same configurations provided in the github repository as in the link? And can I connect sht40 module directly to in100 nanobeacon without connecting to any other power source? The interesting thing I have seen is that when I connect only SHT40 breakout board with IN100 Nanobeacon, the LED in the breakout board doesn’t lit up. But if I connect SHT40 independently with ESP32 the LED turns ON. Also I see from the datasheet that SHT40 typically operates at 3V3 but the CR1220 battery in IN100 nanobeacon can only provide 3V? Is this a critical problem for I2C communication between nanobeacon and SHT40 board? I have observed similar issues also with BME280 breakout board from sparkfun.

Voltage is OK, I think current is not sufficient. Test with the 3.3V pin of an Arduino UNO and see if the on board LED lights up.
