The latter is also referred to as NB-IoT or Narrowband IoT. This cellular communications technology leverages existing 4G infrastructure but offers differently configured services in relation to data throughput and network reach.

BLUETOOTH Bluetooth is a short range communications protocol, ideal for wearables and other close range applications. PyGo will support Bluetooth Low Energy and classic Bluetooth specification Compliant with Bluetooth v4.2 BR/EDR and BLE specification Class-1, class-2 and class-3 transmitter without external power amplifier Enhanced power control +10 dbm transmitting power NZIF receiver with -98 dbm sensitivity Adaptive Frequency Hopping (AFH) Standard HCI based on SDIO/SPI/UART High speed UART HCI, up to 4 Mbps BT 4.2 controller and host stack Service Discover Protocol (SDP) General Access Profile (GAP) Security Manage Protocol (SMP) Bluetooth Low Energy (BLE) ATT/GATT HID All GATT-based profile supported SPP-Like GATT-based profile BLE Beacon A2DP/AVRCP/SPP, HSP/HFP, RFCOMM CVSD and SBC for audio codec Bluetooth Piconet and Scatternet Soon to be released BLE Mesh profile So, when you add all that up, you'll get to a point where you are probably thinking...mesh. I can mesh that too... and you can! Espressif will release their BLE MESH to the general public soon, we hear.
