Issue with SoftDevice 132

[ekawahyu]

I am having issue with SoftDevice 132, Sandeep Mistry fork. If I build the sketch without SoftDevice, the SoftwareSerial seems to work just fine. But I see some gibberish output for the same sketch with SoftDevice. Is this a known issue, or am I missing anything? Please let me know if you need further info, thanks.

Can you link it? I'm not familiar with it, so it's likely my SS code conflicts

Here is the link to my Arduino-nRF5 fork with added SoftwareSerial library, and WInterrupts.c patch:

I use port 0 (RX) and 1(TX) with constant data coming in from GPS. When I built SoftwareSerialExample sketch without SoftDevice, I can see all GPS data coming in just fine at 9600 bps. But once I added SoftDevice, then all GPS data become gibberish. What do you think causing it?

I still have no idea how to fix this thing. I don't see anything wrong with the code, unless there is issue with interrupt priority?

The only thing I can see is that your code seems to be missing the changes to attachInterrupt that i proposed here. sandeepmistry/arduino-nRF5#205

You mean the changes in WInterrupt.c and its header? I have it here: https://github.com/ekawahyu/arduino-nRF5/tree/micooke-pr205

Ah, yep. Sorry then I'm not sure. Have you tried other pins incase the Softdevice is using those for something else? I'm not much use at the moment, sorry, but I don't have access to my Arduino devices at the moment

yeah, I tried D0-D5 with no luck, I may have to use a breakout board and try it again, making sure that there is absolutely no peripheral attached to those pins. But the thing is, it works when I build the example without S132. But when the S132 is in, then all I can see is the gibberish output. Really weird.
