Sorry for not getting back to you sooner, have you had any progress on this issue ?

RE: BLE stumbles without RTT Viewer.

The SEGGER_RTT_CONFIG_DEFAULT_MODE setting you mentioned is already 0.

Let me explain the phenomenon in more detail.

Flashing Firmware from SES to Ctrl+T+L.
I've set up BLE Advertising after the LED lights when Firmware runs.
But the LED doesn't turn on.
In other words, Firmware does not run immediately after Flash.
Of course, I can't check BLE either.

However, LED and BLE turn on when F2 is pressed in RTTVviewer to start logging.
I'll call this "STATE1".

In "STATE1", when I press F3 to disconnect the RTTVviewer, it sends data very stumbly as shown in the video.

But in a state of "STATE1" physically disconnect the SWD and SWC, LED and BLE are still working fine.
I'll call this "STATE2".

When I physically disconnect power from "STATE2" and reconnect and reboot, the LED lights up, but the BLE is not responding.

in conclusion

SWDSWC plug-> Flashing -> LED:off , BLE:off

SWDSWC plug-> Flashing -> SWDSWC unplug -> nRF reset -> LED:on, BLE:stumble

SWDSWC plug-> Flashing -> connect RTT -> LED:on, BLE:on

SWDSWC plug-> Flashing -> connect RTT -> SWDSWC unplug-> LED:on, BLE:on

SWDSWC plug-> Flashing -> connect RTT -> disconnect RTT -> LED:on, BLE:stumble

It seems as if the Connect, Disconnect command in RTTVviewer has some effect on Softdevice.

Here I attach the sdk_config.h code of my clock and RTT.

RE: BLE stumbles without RTT Viewer.

JONATHAN LL — Mon, 31 May 2021 11:57:20 GMT

What is SEGGER_RTT_CONFIG_DEFAULT_MODE sett to ?qw

// <i> The following modes are supported:
// <i> - SKIP  - Do not block, output nothing.
// <i> - TRIM  - Do not block, output as much as fits.
// <i> - BLOCK - Wait until there is space in the buffer.
// <0=> SKIP 
// <1=> TRIM 
// <2=> BLOCK_IF_FIFO_FULL

If it is sett to 2 then that might be the issue, otherwise see if everything is initialized correctly, clocks and timers.

Jonathan

yes. only works right when RTT is on

JONATHAN LL — Fri, 28 May 2021 14:49:44 GMT

Hi,

Just to be on the same page, as the Software is now it only works as expected if RTT is on?

Jonathan
