no BMP280 found

[Frafly]

Hello group. I hope you can help me. I switched from SoftRF (1.7) to Moshe's version (SoftRF.mb166.esp32) with the TTGO T-Beam. Now the BMP280 is no longer recognized. It's connected to pins 21 and 22. I don't have an OLED installed. If I switch back to 1.7, it works again.

(1.7)
BMP180 barometric pressure sensor is detected.
Temperature = 24.80 *C
Pressure = 98776 Pa
Altitude = 214.25 meters

(mb166)
calling Baro_setup()...
baro setting up
BMP280 not found on pins 2, 13...
probing BMP280 on pins 21, 22...
Barometric pressure sensor was NOT detected.
... Baro_setup() returned

Does anyone have any idea what I'm doing wrong?
Thanks

Welcome Frank!  It seems from the captured SoftRF USB output that you have a BMP180 not a BMP280?  I have ran into a problem in my version of SoftRF a while back (when I switched to a newer version of the ESP32 library for the Arduino IDE) and the probe for the BMP180 would crash.  I found no solution to that problem, so I removed support for the BM180.  I.e., when my SoftRF boots it probes for a BMP280 but not for a BMP180.  It does work with the BMP280, which is a better sensor than the BMP180, and is cheap, so replacing the sensor board is probably the best solution for you?

Hi Moshe, Thank you very much for your quick and detailed response — and especially for your project.
I should have read the output more carefully; then I would have seen that it's a BMP180.
Unfortunately, the board is labeled BMP280 :-(
I'll replace it with a 280.

  Thanks again!
