BLE and I2C conflict on Nrf51822

Hi I am trying to run the BLE Heartrate example and also doing some I2C reading in parallel. The code runs for a few minutes and then hangs. In case I comment out all the code for ble the I2C keeps running good and vice versa.

I found this here: https://os.mbed.com/questions/5588/Problem-using-I2C-with-BLE/

The OP got it working by using the mbed src library. Just wanted to know if this has been fixed in the latest mbed build. Thanks.

Hi,

Unfortunately it is still known bug that I2C slave and BLE does not work at the same time in these boards.

Thanks for the reply. Any known work arounds or pointers in the right direction?
