All the advantages of theDA14585with greater flexibility!
The PAN1740A is an optimized version of the PAN1740, offering a reduced boot time and supporting up to 8 connections to allow greater flexibility to create more advanced applications. It can be used as a standalone application processor or as a data pump in hosted systems. The device is optimized for remote control units (RCU) requiring support for voice commands and motion/gesture recognition. The Bluetooth® Low Energy firmware includes the L2CAP service layer protocols, Security Manager (SM), Attribute Protocol (ATT), the Generic Attribute Profile (GATT) and the Generic Access Profile (GAP). All profiles published by the Bluetooth® SIG as well as custom profiles are supported. Panasonic cost engineering lowers component count and the application BOM. With a fully shielded case, integrated crystal oscillators and chip antenna, the 9.0 x 9.5 x 1.8 mm footprint of the PAN1740A makes it one of the smallest Bluetooth low energy modules available.

Multiple connection
Posted byBenjaminDu135 points 3 repliesHi dialog,
I modified DSPS(with reference to DA14531-DA14585-586_Multirole_Example) to be multiple connectable.
When multi-connected,I want the master to receive data from all the slaves inuser_sps_client_data_rx_ind_handler(for examplearch_printf("%s\t",(uint8_t *)param->data);), but I can only receive data from one slave.
Can you help to analyze the reason?
Thanks
Benjamin

Hi Benjamin,
Please check out this SW Example :
This example applies for DA14585/586 as well. The project works as a Central connecting to 2 peripherals, and once connected, it advertises so another central can connect to it.

Hi Benjamin,
Thanks for coming and posting on our new forum. The DSPS is supported "as is" and provided. Multiple BLE connections are not supported by the DSPS. If you check the DSPS webpage and the user guide (links is provided below), you will see that emulates a serial cable communication and so provides a simple substitute for RS-232 connections.

For multiple connections, theDA14585/DA14586 - DA14531 Multiperipheral Exampleshould be used. DA14531 is able to support up to 3 and the DA14585 up to 8 simultaneous connections.
Thanks, PM_Dialog
