• @Gordon and @fanoush, thank you for your responses and suggestions. I tried your suggested tests and all returned 255.
    I searched and found this link that shows exactly same readings from Bangle.getAccel() or Bangle.accelRd(0x0F).
    I have checked the PCB closely and couldn't find any solder that might short any connections. My guess is when I replaced the battery, somehow the accelerometer got messed up internally. The link above says it was fixed after draining the battery, so I would try that.
    Thank you.
