can nRF52 connected with nRF51 and Mobile Bluetooth 4.x ?

[milav]

Hello,

This is Milav Soni from Teq Diligent,India.

I explore the nRF52 series Chip and nRF51 series chip.

I also explore some of your BLE video.

I have one question regrading the connection of two BLE enabled Chip.

My questions is..

1. Can nRF52 series chip connected with BLE to nRF51 series Chip? means nRF52 acts as a broadcaster and nRF51 acts as a Observer? or vice versa .. after making a connection data will be communicate with each other?

2. The same thing above is with Bluetooth mobile 4.x version.

   Can nRF52 series chip connected with BLE to Bluetooth mobile 4.x? means nRF52 acts as a broadcaster and Bluetooth mobile 4.x acts as a Observer? or vice versa. after making a connection data will be communicate with each other?

Please Give me a right solution.

Thank You Milav

Hello Milav,

The answers to both of your questions are YES. Purpose of Bluetooth Low Energy standard is exactly this: interoperability of different devices from different vendors in various architectures. So as long as both part of the link have Bluetooth LE compliant stack they should be able to talk to each other (actually there is one more condition: as BT LE link layer is asymmetric then both devices must implement complementary profile so one can be master and one can be slave). If both sides implement GAP&GATT layers (which is today basically >95% of applications) then one of them must be GAP Central (Master) and one GAP Peripheral (Slave), similarly one of them should play GATT Server role and second GATT Client. Before connection is established Central acts as Scanner (Observer if you want) and Peripheral as Broadcaster (Advertiser if you want).
