Device Information
- Module: FANSTEL BC832 Bluetooth Low Energy 5 Micro Module
- Chip: nRF52832
- Firmware version: Default AT firmware
- Current MAC Address: ef30:0a:cab132
Issue Description
I'm attempting to configure my BC832 module (which uses the nRF52832) to function as a central device using the default AT command firmware. However, I'm encountering consistent errors when trying to set or query the device role. The module responds successfully to basic commands but fails when attempting to change roles.

Response to AT+ROLE=1: FAIL
Response to AT+ROLE=0: FAIL
Response to AT+ROLE?: FAIL- Does the default AT firmware for BC832/nRF52832 support changing between central and peripheral roles? If yes, what is the correct command syntax?
- If AT+ROLE is not supported, what is the appropriate command to change the device role from peripheral to central mode?
- Is it possible that this particular firmware version is locked to a specific role? If so, how can I determine which role it's currently set to?
- Are there alternative commands (AT+MODE, AT+WORKMODE, AT+BLE_ROLE, etc.) supported by this firmware that would accomplish the same task?
- Is there a command to list all supported AT commands for this specific firmware implementation?
- If role switching is not supported in the default firmware, do you provide an alternative firmware version that includes this functionality?
- Are there any specific initialization or configuration steps required before changing the device role?
Additional Details
I've confirmed the module responds correctly to other AT commands including:
- AT+QUITREGISTER
- AT+RX?
- AT+DEFAULT
- AT_RFPW?
- AT+RFPW=
Thank you for your assistance with this technical issue.
