Hi,
I am using nrf_fstorage_sd which uses nrf_atfifo. I would like to know what it is max usage of m_fifo queue so I can set lowest NRF_FSTORAGE_SD_QUEUE_SIZE value. I figured...
I develop an program with BLE DFU support, but we hope to merge all hex as single hex file. Then we can burn this hex file by programer (such as jlink or NRF52DK), So we have...
Hello,
I'm trying to run the s132 (and s140) softdevice while running a proprietary mesh network stack. Naturally I'm requesting a hefty amount of radio slots. I need to...
