BLE FOTA example for Central device

[Miguel Ferreira]

Hi,

Is there any example of a Central device which is able to connect to a peripheral and update it ? Im guessing the bluetooth_central_dfu_smp sample is probably the closest one to what I want.

Thank you!

Yes, that is the closest official sample.

A colleague and me have created this unofficial one which is the bluetooth_central_dfu_smp with some addes features.

Dear Sigurd,

Since this is a relatively recent thread, I thought I quickly chime in to also write down my observations about your smp_client_ble example (which is really useful btw in light of no official examples...).

1. The image hashes don't match if checked with mcumgr-cli
2. Upload process errors at 97%, but the image seems to be transferred correctly. A reset must be done to the smp_client.
   
3. Pressing button 4 on the smp_client DK gives the following error:

I'm seeing similar issues with NCS 2.2.0 and NCS 2.3.0 as well.
Reading a bunch of threads in the forum, I think it will be really nice once your mentioned PR will be merged, and/or will be included in the NCS.
