Hello zephyr community.
I have recently try to use the xG24-DK2601B board with the SMP server sample.
At the moment I'm stuck when trying to upload the signed firmware over BLE, I'm using NRFConnect on Android and you can see attached a log that illustrate the disconnection. Log_2024-05-08_13_48_01[1].txt
What's very hard to debug is I have no error on the NRF side and no error as well via UART on the dev kit. I can only see that I'm disconnecting systematically at the same time.
I'm using the latest version of zephyr, no change on the code but this flag
CONFIG_MCUMGR_GRP_OS_BOOTLOADER_INFO=y
that I have added because NRF logs were requesting this info and the not supported error popped up.There is a warning about controller host flow not supported but I have no idea if that's important or not.
On a side note, I did the exact same operation (firmware update via BLE using NRF connect) with an NRF52832 dk successfully.
I have also tried the firmware upload using serial communication with the xG24-DK2601B board successfully. I had to add
zephyr,uart-mcumgr = &usart0;
in the dts and makes me wonder why no silicons labs have this set already ?Any hint on how to investigate this problem would be very very helpful.
Thanks, Adrien M.
