Is it possible to read the state of the charging LED on RAK19007 by RAK4631?
The link to Figure 16 of the RAK19007 datasheet is broken.
As an alternative, I could read the battery voltage and the solar input. If the last is higher, the battery should be charged. But is this a satisfactory solution?
Hi Claus,
The charging LED is controlled by the charger chip. The MCU has no access to it.
The battery voltage can be read through WB_A0 analog input, but you cannot measure the solar input, it is only connected to the charger chip.
Thanks for the info about the missing schematic. I will inform the doc team to fix it. It has only the connectors on it.
