BL600 HW reset (active low). Pull the nRESET pin low for
minimum 100mS in order for the BL600 to reset.
Note:
For BL600-Sx-02 or BL600-Sx-03: To ensure nReset functions properly, you MUST place a 12K
resistor to GND on BL600 pin 23 (NC/SWDCLK) on your host board.
For BL600-Sx-04 or higher: Do not fit a resistor to GND on BL600 pin 23 (NC/SWDCLK).

Miscellaneous (Hidden JTAG)
The BL600 SW consists of:
BL600
smart
BASIC runtime engine FW (loaded at production, may be upgraded customer).
BL600
smart
BASIC application script developed by customer (loaded through UART by customer).
To allow customer the capability to upgrade the BL600
smart
BASIC runtime engine FW, to the latest version
released from Laird), the current
smart
BASIC runtime engine firmware (v1.5.66.0 and since v1.2.54.0) allows
upgrading
smart
BASIC runtime engine FW over UART. Upgrade
smart
BASIC runtime engine FW via the hidden
2-wire (JTAG) interface has been supported since v1.1.50.0).

Connect 12 K resistor to GND (BL600-Sx-02 and
BL600-Sx-03 only).
Laird can supply JTAG J-link programmer for this.
Only requirement is that the customer should use the following JTAG connector on the host PCB.
The JTAG connector MPN is as follows:
