5.9 nRESET pin

Table 18: nRESET pin
Signal Name
nRESET
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).

5.11 Miscellaneous (Hidden JTAG)

The BL600 SW consists of:
smart
BL600 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
released from Laird), the current
smart
upgrading BASIC runtime engine FW over UART. Upgrade
2-wire (JTAG) interface has been supported since v1.1.50.0).

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:
