[Susheel Nuguru]

On SDK 12.0.0, SDK 12.1.0 and SDK 12.2.0 only

Please Do not judge the quality of SDK based on number of entries here. This thread should be considered as part of Nordic effort to find issues and possibly give a workaround to maintain the quality of the release.

GENERAL RULE TO KEEP THIS PAGE READABLE

• This is ONLY for already confirmed bugs which are discussed in another threads. Please do not discuss here in the comments to try to figure out that the issue you are facing is a bug or not. Please create a separate question.

• Do not edit the answer. If I forgot an already discussed and confirmed bug, then please add the link to the issue in comment, I will then update the answer with your link.

• If it is a minor edit, then I will select "minor edit" option in my edits. But if i am adding new issue, then I will not select "minor edit" and hence will send notifications to one following. Click "Follow" the case to get notification.

Fixed in this SDK12.x.0 release.

1. APP_FIFO:app_fifo_write when trying to write zero bytes will actually write one byte

2. SPI slave, if TX and RX buffers are not same then the callback handler is called with correct data but swapped TX and RX length in the event

3. Peer Manager replaces Device Manager, all device manager issues are not tracked anymore

4. Bug in the advertising module when switching from whitelist mode to non-whitelist mode

5. IAR Warning[25] in iar_startup_nrf5x.s: IRQ handlers is defined pubweak in a section implicitly declared root

6. Issues in DTM negative power

7. High power consumption when using FPU (This is hardware issue and documented here and an example for workaround is given in FPU example in SDK12. If application enables FPU, it is application responsibility to apply this workaround)

8. FreeRTOS tick count invalid when using tickless idle (Patch has been applied, so it will stay here as fixed unless someone still sees missing ticks)

9. Unexpected indicated connection security with connectivity firmware(Serialization is removed in SDK12 because the underlying softdevice version does not support it yet. It will be added back when S132 softdevice supports it)

Inherited from older SDK(s)

1. nrf_svc.h cast missing for cpp compilers

2. QDEC example SAMPLEPER Register'Problem (fixed in nRF5 SDK 12.2.0)

3. bug in nRF52 in bootloader_dfu when disabling all interrupts

4. UART logging only one character

5. GCC RAM settings in softdevice//toolchain/armgcc/.ld does not match Softdevice

6. Peer Manager fail to save a bonding data

7. Peer manager types declaration incompatibility with non C99 compilers (This is not a bug as SDK for now officially does not support non C99 compilers, but this thread made it here to make other aware of it)

8. ble_db_discovery failed to initialize correctly when repeats the service discovery

9. Ble_radio_notification wont compile

Newly found issues

1. filename case changes causes missing file errors in non windows machine

2. SDK12 armgcc has warnings about missing include paths (fixed in nRF5 SDK 12.2.0)

3. ble_app_buttonless_dfu not working

4. ble_app_buttonless_dfu not resetting to bootloader

5. Peer manager LESC 'Just works' Pairing bug

6. nrf_drv_uart compile error (fixed in 12.1.0)

7. C++ related compile issues

7.1) ant_stack_handler_types.h compilation error in C++ and ANT_STACK_SUPPORT_REQD not defined

7.2) C++ compilation error in gzll header files

7.3) Missing C++ guard closing bracket in nrf_ble_ancs_c.h (Only SDK 12.2 and SDK 12.3)

8. ble_error_log.c has a reference to pstorage.h which has been removed. (internal ticket number NRFFOETT-1514)

9. sdk_resourcesh-does-not-build-with-gcc

10. Unecessary high RAM usage if NRF_LOG_BACKEND_SERIAL_USES_RTT is set (fixed in nRF5 SDK 12.2.0)

11. app_pwm high current consumption(fixed in nRF5 SDK 12.2.0)

12. ANCS array index bug

13. Bootloader erased after flashing buttonless example

14. Application Interrupt priority validation error (fixed in nRF5 SDK 12.2.0)

15. BLE_GAP_TIMEOUT_SRC_ADVERTISING event not forwarded to SDK modules

16. Error compiling nrf_esb.h

17. FDS issue with Garbage Collection

18. Bug in flashwrite example

19. RAM settings in softdevice//toolchain/armgcc/.ld do not match Softdevice (fixed in nRF5 SDK 12.2.0)

20. documentation error with nrf_crypto_shared_secret_compute

21. NFC on nRF52832 doesn't work if HAL_NFC_FIELD_TIMER_PERIOD is set to maximum value

22. MAC address randomly set to 00:00:00:00:00:00

23. BUG in nrf52_common.ld

24. armgcc Makefiles have wrong 'erase' commands for nRF51

25. ESB: mismatch between code and documentation

26. mismatch in the device check in nrf_peripherals.h (NRF52832) and the backwards compatibility redefine of NRF52 to NRF52832_XXAA

27. SAADC Sample Convert Bug

28. nrf_drv_adc_buffer_convert() limited to 255 samples

29. Eddystone EID slot's IK is not properly restored from flash on POR (fixed in SDk13.0.0)

30. Timer2 in PPI example not initialized correctly
