Android app issues for OTA DFU nRF

[nordicuser123]

Hi,

I am seeing a couple of issues in my Android mobile app while doing a DFU:

1. The DFU stops in the middle with this log on the debugger 

I/art: Starting a blocking GC JitCodeCache
I/art: After code cache collection, code=86KB, data=70KB

2. DFU stops because of disconnect

03-22 17:26:42.865 10283-10343/I/DfuImpl: Creating Data object (Op Code = 1, Type = 2, Size = 4096) (3/16)
03-22 17:26:42.926 10283-10343/I/DfuImpl: Uploading firmware...
03-22 17:26:43.855 10283-10296/E/DfuImpl: Characteristic write error: 1
03-22 17:26:43.856 10283-10343/E/DfuBaseService: Uploading Firmware Image failed (error 1) 

Any insights you can provide on these issues would be great.

Hi,

Have you tried to do DFU with our nRF connect / nRF toolbox app? This could indicate whether or not it is a problem in the app, or if it is in the bootloader.
