Can BL600 Firmware be upgrade over BLE?

Answer

I am using a BL600 Bluetooth module in my device and I was wondering if there is any way to upgrade the BL600 over BLE? Do you have open protocol to update firmware over BLE? Or maybe you have your own mobile application for upgrading?

Due to memory limitations the firmware (FW) updates cannot be loaded to the BL600 Over-the-Air (OTA) via BLE. Virtual Serial Port (vSP) only provides a serial connection, which streams the information one single bit at time. Additionally, the vSP buffers, located in the RAM only allocate 256 bytes for Rx buffer and 256 for the Tx buffer, which is not sufficient for transferring the firmware update, for subsequent processing of the upgrade on the module. Only smartBASIC applications can be loaded to the module OTA. Therefore, due to the memory limitations, it is not possible to load FW updates OTA. This would require having enough memory on the module for two copies of the FW, which the BL600 does not have. All firmware upgrades must be performed via a JTAG or UART connection as per the attached documents: BL600 Firmware Upgrade over JTAG
