for NCS SDK, the speed of SMP OTA by BLE is very slow ?

[FrankWang15]

Hi,

Developing by NCS SDK, We found it will take 20 minutes by using mcumgr(on MacBook-pro) to BLE OTA 178KB image to nRF52840 Product Board's external SPI FLASH. it success, but very slow.

is it normal for such a low speed ?  Or we make any mistake ?   

Best Regards
