Replace Flora BLE on our current prototype with another BT device that can support 115200 baud

$750-1500 USD

$750-1500 USD

Paid on delivery
Current Scenario: Please review the simplified block diagram. The Flora BLE is connected to the Flora MCU. The Flora BLE transmits at the rate of 9600 baud but even at this baud rate it drops a lot of values. On the receiving side we have an nrf51 dongle that captured the data via COM port in to a file. Our windows application reads this file and processes the data further Ideally we want to transmit at 115200 without any data loss. Required solution: BT native component selection that can replace the Flora BLE and stream in UART mode at 115200 and USB dongle for the PC than can receive it via USB/COM. Simple connections as shown in the schematic for ease of soldering / connecting. Can be any native BT profile. Should work on 3.7V Li-ion battery.

There are several features for use with Arduino code. You really need to do 115200bps, or carry out a stable connection. I have a project with the same application, has recently been done, have also been observed similar problems. Basically, can solve the problem of optimizing the code. If you need traffic to 115200bps, I can also solve this. And design good PCB, after full check code.

CSR-based bluetooth > uart dongles are like $10/ea and have zero problems reliably transmitting at 115200 baud (within reasonable distance, of course). Not sure what the problem with Flora BT module is, have you actually tried setting baudrate on it higher? Also character loss could be anything from the transmitter end not properly sending to receiver dropping them, so I wouldn't be 100% sure the problem is due to one end or another without more information. Anyway, I'm not sure why the budget is so high, you just want a breakout module to replace flora BT, right? In that case its like a $10 thing. however if you're asking to develop a new PCB which contains these parts, then the bid will be higher. please clarify.

I have experience using Bluetooth with arduino, I have used the most common Bluetooth module HC-06 and HC-05 which works fine at that baud rate.

Hello! I'm a brazilian engineering student and in my final course work, i use the wirelles comunication. I'm working with two bluetooth modules and one of them was the flora BLE, so I needed replace this, if you whant I can help you and show you how I did and I can make the same for you. Thank you for you consideration, Cássia.
