[jira] [Created] (MYNEWT-881) SensorAPI: LIS2DH12 set threshold
callback cannot get called multiple times
Vipul Rahane created MYNEWT-881:
-----------------------------------
Summary: SensorAPI: LIS2DH12 set threshold callback cannot get called multiple times
Key: MYNEWT-881
URL: https://issues.apache.org/jira/browse/MYNEWT-881
Project: Mynewt
Issue Type: Bug
Security Level: Public (Viewable by anyone)
Components: Sensor Framework
Affects Versions: v1_3_0_rel
Environment: ruuvitag-revb2
Reporter: Vipul Rahane
Assignee: Vipul Rahane
Fix For: v1_4_0_rel
There are two issues for calling the lis2dh12_sensor_set_trigger_thresh():
1. gpio irq was not being released before doing a re-initialization
2. srec was malloced and calling the function multiple times would have malloced additional memory without freeing it.
Solution:
1. Release the gpio irq
2. Remove the malloc and add a ptr for the sensor in each type trait so that a sensor read could be performed in the irq handler.
