The Nordic52832 chip supports not only BLE but also a proprietary 2.4G communication protocol. BLE, being a standardized protocol stack, allows relatively simple communication between devices. However, the proprietary 2.4G communication protocol poses challenges for interoperability due to variations in private configurations across different manufacturers.

This module is based on STMicroelectronics' STM32WLE5CCU6 chip solution and incorporates an Arm Cortex-M4 MCU and Semtech's SX1262 baseband. It does not require an external MCU for primary control.

Support for disabling a specific constellation is not available for modules that support RTK. However, for modules that do not support RTK, such as MS35SN1, disabling of constellations can be achieved through specific commands.

 The AT+CWLAPOPT command can be used to achieve this functionality.

 The AT+CWRECONNCFG command can be used to set the automatic reconnection attempts. A value of 0 means it will always attempt to reconnect, and the range can be set from 1 to 1000.

The default value for the AT firmware is 0, which means it will not reconnect to the AP after disconnection. 

To use special characters, they need to be escaped. For example, if the SSID of the target AP is "AAA,b" and the password is "123456789", the command would be: AT+CWJAP="AAA\,b","123456789"\"
