It would be good to add a similar implementation for SoftDevice. It could probably look something like this completed untested bit of code: ```go func (c DeviceCharacteristic) GetMTU() (uint16, error)...

I think it is time to merge this. It may not have the MTU function in the place we would want it, but there is not much we can easily...

I downloaded that file: ``` $ md5sum ~/Desktop/flash.uf2 324c2f847d71fcd64a9afec68e036aa4 /home/ron/Desktop/flash.uf2 ``` Copied to my Circuit Playground Bluefruit. Appeared to flash as expected, but no data coming from USB CDC. BTW...

Yes, I have updated the bootloader. I previous tried with several different of the most recent versions (0.4, 0.5) actually just to be sure. Did not help.

This is where I obtained the updated bootloaders from: https://github.com/adafruit/Adafruit_nRF52_Bootloader/releases

Additional update: this package worked within last couple of months with v0.4.0 bootloader on my ItsyBitsy nRF 52840 board. So it is not just a question of bootloader version.

Any updates on this by any chance? Or ideas on how it could be debugged?

OK this is a bit weird. The file you sent worked as expected even with bootloader 0.5.0. Then I tested with the latest TinyGo release, and it also worked as...
