caco3 opened a new issue #15: URL: https://github.com/apache/mynewt-mcumgr-cli/issues/15
This is a redirect from https://github.com/zephyrproject-rtos/zephyr/issues/27331 Hi all I am trying to get the "SMP Server Sample" (https://docs.zephyrproject.org/latest/samples/subsys/mgmt/mcumgr/smp_svr/README.html) working. I have a nrf52840dongle_nrf52840 and successfully installed MCUboot (option #2) and the "SMP Server Sample" on it. I also have a laptop with a built-in BLE radio. I successfully can test the connection and even list the image: ``` > mcumgr --conntype ble --connstring ctlr_name= peer_name='Zephyr' echo hello hello ``` ``` > sudo mcumgr --conntype ble --connstring ctlr_name=peer_name='Zephyr' image list Images: image=0 slot=0 version: 0.0.0 bootable: true flags: active confirmed hash: 37a4a9403fbd0a0336152646947ccce5faf6674e3a29b4220eb2b97a2f613b9d Split status: N/A (0) ``` How ever when I try to upload a new image, I run into an error: ``` > sudo mcumgr --conntype ble --connstring peer_name='Zephyr' image upload smp_svr.signed.bin -t 100 0 B / 182.61 KiB [--------------------------------------------------------------------------------------------------] 0.00% panic: send on closed channel goroutine 493 [running]:
