Hy world,
I can update my device with FOTA, but the first time i do:
1 I put: "ble_default_bootloader.hex" on board;
2 i open nrfMasterControlPanel app
3 i write characteristic...
I have a feeling I am missing something completely obvious here. That said, this problem has cost me enough time today that I'm willing to risk embarrassment to see if someone...
I'm trying to implement a simultaneous broadcaster observer by calling ble_gap_adv_start() and sd_ble_gap_scan_start() and waiting for respective events.
If I call advertising...
Hello,
I'm trying to use Eclipse with a Nordic SDK (managed build mode) but it seems Eclipse (latest Mars edition) fails to invoke the assembler. Here is what I found in...
We are looking to use the DCDC to reduce the maximum current during radio operations, but minimize the overall current by enabling it as late as possible before radio use...
