Hi all!
I want to use the BLE stack by Nordic. I figured out that S132 is the appropriate HEX image for nRF52832. I can burn the softdevice into flash with nrjftool.
An...
We have an application where certain executions hold more priority over BLE link. We are implementing a critical section(disable/enable interrupts). However, in some corner...
