I2C and BLEPeripheral doesn't work #370

Closed kungfupizza closed 5 years ago

kungfupizza commented 5 years ago

Hi, I am using this core for nRF52832 and the BLEPeripheral and I2C doesn't work on it, the program gets stuck on blePeripheral.begin() or Wire.begin()

I am using S132 SoftDevice 6.1.0.

Any solutions?

EDIT: Also tried S132 2.0.1 as said in readme, but still failed.

I2C should work fine, which board are you using?

As for BLE issues, please post over on the BLEPeripheral issue tracker as that's a whole separate project and I have zero knowledge of it's inner workings.

I made a custom board with I2C pull ups of 4.7K on pin 15 and 16, which I changed in the variant.h file.

Sorry, my mistake. The I2C sensor wasn't getting proper 3.3V and doing some tweaks solved it.
