We have a Mesh app that should be updated via DFU.
The problem is that if a device (for whatever reason) restarts in the middle of DFU or it is powered up later (i.e. not working during DFU), it newer receives update.
Here is a app log (device started after DFU):
<t: 23>, ble_softdevice_support.c, 162, sd_ble_enable: app_ram_base should be adjusted to 0x20002DA0 <t: 489>, main.c, 68, Initializing and adding models <t: 496>, main.c, 111, rom_base 26201 <t: 498>, main.c, 112, rom_end 424D4 <t: 500>, main.c, 113, rom_length 1C2D3 <t: 502>, main.c, 114, bank_addr 43000 <t: 509>, bizlogic.c, 213, Bizlogic init <t: 511>, gap_listener.c, 85, GAP scanner started. <t: 514>, gap_advertiser.c, 74, GAP advertiser init <t: 5389>, nrf_mesh_dfu.c, 529, RADIO TX! SLOT 0, count 255, interval: periodic, handle: FFFE <t: 5398>, main.c, 141, Started. <t: 5510>, nrf_mesh_dfu.c, 391, New firmware! <t: 5512>, dfu.c, 48, NRF_MESH_EVT_DFU_FIRMWARE_OUTDATED_NO_AUTH <t: 5515>, nrf_mesh_dfu.c, 529, RADIO TX! SLOT 0, count 255, interval: periodic, handle: FFFD <t: 5519>, nrf_mesh_dfu.c, 535, Killing a TX slot prematurely (repeats done: 0). <t: 8167>, nrf_mesh_dfu.c, 529, RADIO TX! SLOT 0, count 255, interval: periodic, handle: FFFD <t: 8171>, nrf_mesh_dfu.c, 535, Killing a TX slot prematurely (repeats done: 0).,
Device obviously knows that is should be updated (NRF_MESH_EVT_DFU_FIRMWARE_OUTDATED_NO_AUTH) but it fails to transfer firmware (Killing a TX slot prematurely).
How to fix this?
And also when the update is transmission over the Mesh is stopped?
If we have Client with ID = 1 and Server with ID = 2, and if Server devices are now updated, they still broadcast this new firmware to all devices and if you want to update Client device, before you can start it is already receiving update from Server devices and this update is transmitted all the time.
How to stop firmware re-transmission over the Mesh, so that you can update Client without Server firmware being relayed, because if you send init packet via serial to Client you get *84 78 87*. ?
And how to update Server devices then to newer version after like a day or so if some device is still broadcasting older firmware?
