DA14531 SmartBond TINY Module
6 months agoPosted by pege 15 points 3 replies
I have been testing my own and also some of the default projects with DA14531MOD, and get some strange results.
1. On some of the DA14531MOD samples, I get a high initial current >15mA when connecting the battery for the first time. And since I'm using CR2032, the module sometimes fails to boot the CPU. Any suggestions? The only load I have connected is an I2C sensor on the PO8/PO9 pins. What can be wrong? That the buck/bost detector fails somehow?
2. I couldn't find a clear example code to setup for buck configuration, do you have a sugguestion, as it's not clear from the examples / SDK. Suggestion on that?
3. Had trouble to get the power-consumption down to correct levels, but I found in the EddyStone example that set the SPI_EN pin, and that fixed the issue at hand (from 0.2mA to <0.001 mA). Is that the "correct way of fixing that"?
