The Difference Between BLE Modules BLE5101 & BLE5201

By sdga:NiceRF Wireless Technology Co., Ltd

The BLE modules BLE5101 and BLE5201 are both bluetooth series products launched by NiceRF. Due to they share the same appearance and many similarities in functions, customers might be confused.

In order to help customers distinguish easily, here we listed the features of these two BLE Modules as below.

BLE module BLE5101 and BLE5201


The common features of BLE modules BLE5101 and BLE5201:

  1. Bluetooth MTU (the maximum number of bytes sent in a single packet): 247 bytes;
  2. Operating frequency range: 2400-2483.5MHz (2.4G);
  3. Support low-power sleep;
  4. Support over-the-air upgrade (OTA DFU);
  5. Host connection strategy: UUID filtering (you can view the host connection strategy of the specification);
  6. The maximum time for UART to read data at one time: 50ms;
  7. The maximum number of bound devices: 8;
  8. Support custom 16-bit UUID, including one Service uuid and two Characteristic uuid (Read & Write);
  9. Support manual scan connection and automatic connection (according to host connection strategy);
  10. Same size: 10.82*14.5*2.4 mm
