Is there any easy way to replace UART wired communication with Bluetooth Low Energy wireless communication?
Sample software is provided. LAPIS Technology offers a "Serial Communication Sample Application" to transmit data previously sent to UART to target devices using wireless Bluetooth Low Energy communication with easy command operation. Based on this sample application, devices previously controlled via wired communication (UART) can easily be allowed to be wireless ready. This sample software is available on the LAPIS Technology Wireless Support Site.* At the first login, user registration is required. http://www.lapis-semi.com/jp/semicon/telecom/#supportsite-login
If there is interference (when radio waves simultaneously transmitted from different transmitters collide), it may be impossible to receive data (SyncWord or addresses) in the first place. Is there a way to avoid missing data to be received due to collision?
If data is transmitted simultaneously on the same channel, it may become unable to receive the data due to the RF interference characteristics. However, ARIB STD T-108 requires CCA to be performed before transmission. For this reason, there is a mechanism to avoid interference due to simultaneous transmission from nearby transmitters.

Is there a way to prevent interference between the transmitted radio waves from two transmitters? If possible, how many sets can be done?
The following two methods can be considered. (1) Identifying by changing SyncWord(When transmitter-receiver is one-to-one) The setting can be up to 4Byte (2^32) of SyncWord setting. Except patterns with extremely large number of 1's or 0's, it is assumed that approximately 2^24 patterns can be used. (2) Managing addresses When one transmitter (master) and multiple receivers (slaves) exist, set the addresses of the slaves. The slave units receive only packets destined to themselves (addresses) (using field check function). Addresses can be assigned for up to 2^48-1 units (6 bytes).

想问一下Transmit buffer和Transmit /Receive FIFO有什么区别？使用Transmit buffer方式扩展性更好吗？
fifo一般都是有缓存器而已，应该是fifo的适配性更强吧
For BD37033FV-M,BD37034FV-M,BD37524FS,BD37534FV,BD37543FS, What is the level meter function?
The Level Meter is a circuit that outputs a DC voltage proportional to the magnitude of the signal and holds the peak level of the detected signal. Since the held peak level can be reset by resetting the Level Meter, the transition of the peak level can be monitored by periodically performing a reset. The reset interval should be at least one cycle of the frequency to be monitored.
In the FSK mode, when continuously transmitting the modulated wave using RF_TEST_MODE, the center frequency shifts by about 3 KHz.
As described in the data sheet, when using RF_TEST_MODE in FSK mode, the modulator reads unnecessary data before the generation of the expected test data just after TX_ON is started up. Therefore, the center frequency changes. To use RF_TEST_MODE correctly, check again through the following procedure. 1. Initialization register setting 2. Execute VCO_CAL 3. TX_ON 4. After starting up TX, MODEM reset * Note: Usually, this event does not occur when transmitting packets containing DIO control. So, it is not required to perform a MODEM reset after TX_ON. This is also an event specific to FSK mode. There is no problem in GFSK mode. Related Products: ML7344/ML7406 family, ML7345 family, ML7404, ML7414

For Analog Audio Processors, Do I also need to set the registers to its initial values?
When power is turned on, be sure to send data to all addresses as initial data. It is also recommended to mute the device until the initial data is transmitted.
Is LE Audio supported?
No, it is not supported. LE Audio is an optional feature of Bluetooth v5.2. Neither MK71511 nor MK71521 supports this function.
What happens if there are less through holes on GND for the back side GND pad of the chip?
GND may be shaken and various RF characteristics would be worse. Even if 12 through holes are used, the same situation would happen unless connected GND plane is strengthed. Related Products: ML7344/ML7406 family, ML7345 family, ML7396 family, ML7404, ML7414
Firmware or other program modification is executed by LAPIS?
We don't have program modification service.
After setting the register value of [PA_ADJ1 to 3] register (B1 0x04-0x06), [PA_REG_ADJ1 to 3] register (B1 0x33-0x35), [PA_REG_FINE_ADJ] register (B1 0x13) through adjusting PA of ML7396, how long does it take for them to be reflected in the wireless output?
After completion of register settings, the control signal is sent to the PA without time lags. Therefore, the time taken for them to be reflected is almost equivalent to the response time of PA. Since PA provides quick response, they are reflected within 100 us. Related Products: ML7396 family
