7. AT+BTF=”<string>”
8. AT+BTN=”<string>”
9. AT+BTN? {Read Friendly Name from Non-volatile Memory}
10. AT+BTF<bd_addr> {Get Remote Friendly Name}
11. AT+BTP
12. AT+BTQ
13. AT+BTG
This sets the friendly name of this device as seen by other devices. The new name becomes immediately
visible. Any name set by this command will be lost on next power cycle.
Please refer to S register 593 (Table 4.1) too.
Response: <cr,lf>OK<cr,lf>
This sets the default friendly name of this device as seen by other devices. It will be stored in non-volatile
memory. The new name will become visible to other devices on next power cycle. Use AT+BTF to make
the name visible immediately. Use AT+BTN? to read it back. An empty string (“”) will delete the string
from non-volatile memory which will force the default name to be used which is “Laird BTM 789012”.
The digits in the default friendly name represent the last six digits of the local Bluetooth address.
Please refer to S register 593 (Table 4.1) too. If a new value of S593 needs to be retained permanently,
save it to non-volatile memory by “AT&W”.
Response: <cr,lf>OK<cr,lf>

subsequently). For permanent discoverable/connectable settings, please refer to S Register 512.
Response: <cr,lf>OK<cr,lf>
Make the device discoverable but not connectable. Being discoverable implies that this device will
respond to inquiries from other devices (inquiry scans enabled).
The setting remains valid until next reset or power cycle (unless not changed by any other AT command
subsequently). For permanent discoverable/connectable settings, please refer to S Register 512.
Use AT+BTX to make the device not discoverable.
Response: <cr,lf>OK<cr,lf>
