We use several Nordic chips in our BLE sensors. We bond to the devices from Android, connect to update configurations, then disconnect such that the device then advertises...
Hi all,
I'm having a error on my code, and wanted to understand it better. I'm using a custom board with a Rev.3 CTAA chip, 256k Flash and 16k Ram. I have BLE initialized...
I measured my Nrf51822 current:
when my VCC is 3.0v ~ 3.3v
my current is 0.16 mA.
when my VCC is 2.6v ~ 2.8v
my current is 1.5 mA (why?)
when my VCC is lower than 2...
