The CHIPSEN BoT-nLE521 module is an OEM-style, cost-effective, low-power, true system-on-chip (SoC) for Bluetooth Smart (Bluetooth low energy) BLE applications. Integrating the BoT-nLE521 into your design enables robust BLE slave nodes to be built with very low total bill-of-material costs while greatly simplifying and streamlining the design and certification process.
BoT-nLE521 combines an excellent RF transceiver with an industry-standard enhanced Cortec-M4 CPU, in-system programmable flash memory, 24kB RAM, and many other powerful supporting features and peripherals.
The BoT-nLE521 is suitable for systems where very low power consumption is required. Very low-power sleep modes are available. Short transition times between operating modes further enable low power consumption.

RF Certification Fee Exemption
If you create a wireless product using an uncertified module, you must obtain your own wireless certification. The BoT-nLE521 already has multiple certifications (SIG, KC (including wireless EMC), FCC, CE and TELEC), reducing the cost and certification process of manufacturing your wireless products.
| Uncertified Bluetooth Module | BoT-nLE521 |
| Complex authorization process | KC+EMC, FCC, CE & TELEC certified |
| Wireless RF certification cost | Wireless certification exempt |
| Certification cost by country when exporting | Certified in the US, Europe & Japan |
| If authentication fails, replace the entire module | |
| Bluetooth logo not available | Bluetooth SIG certification completed |
| No technical support during the certification process | Certified samples and CHIPSEN technical support |
Low Power Consumption

Bluetooth Connection Methods
BoT-nLE521 Master and Slave Modules
A BoT-nLE521 slave module can communication with a BoT-nLE521M master module.
In this configuration the BoT-nLE521 Master will attempt to connect to the BoT-nLE521 Slave. If the Slave accepts the request, the connection is successful.
When communicating between modules there must be a Master and Slave pair. Modules of the same role cannot communicate with each other, i.e. two Slaves cannot communication with each other.
Smartphones and other Bluetooth Masters to BoT-nLE521 Slave Modules
The BoT-nLE521 Slaves will advertise their device information. They can be searched for by smartphones and other master devices, and and connection attempts are received.
