[Bug]: T-Beam Supreme - No environmental telemetry data (BMP-280) #2524

Hardware

T-Beam S3

Firmware Version

2.1.14.fbcd6743

Description

After solving the display issue (see #2519), which was - to my understanding - due to missing power up of the display, all I2C sensors of the T-Beam Supreme were properly detected (thanks for the quick support). For unknown reasons the connection to the BMP-280 failed: "Could not connect to detected BMP280 sensor" (see log). Thus no environmental data available. When using SoftRF the sensor works fine. One more remark: Even though a Micro-SD-Card is inserted (FAT formatted) it is not detected, log: "No SD_MMC card detected".

Meshtastic has no sd card support

Looks like the sensor is assumed on the wrong I2C Bus...

Tom9876 commented 1 year ago

The fix works for me. Thanks (according to the LilyGO product description it is a BME280 sensor and not a BMP280)

caveman99 commented 1 year ago

will be fixed in next firmware release. Thanks @lewisxhe
